PROXY STATEMENT FOR THE 2016 ANNUAL MEETING OF STOCKHOLDERS
_______________________________________________________________________________


April 15, 2016

Information About Solicitation and Voting

The accompanying proxy is solicited on behalf of Proofpoint, Inc.'s ("Proofpoint") board of directors for use at Proofpoint's 2016 Annual Meeting of Stockholders (the "meeting") to be held as a virtual meeting on May 26, 2016, at 9:00 a.m. (Pacific Time) via live interactive webcast on the Internet at www.virtualshareholdermeeting.com/PFPT, and any adjournment or postponement thereof. This Proxy Statement and the accompanying form of proxy were first mailed to stockholders on or about April 15, 2016. An annual report for the year ended December 31, 2015 is enclosed with this Proxy Statement. An electronic copy of this proxy statement and annual report are available at http://investors.proofpoint.com.

General Information About the Meeting

Purpose of the Meeting

At the meeting, stockholders will act upon the proposals described in this proxy statement. In addition, following the meeting, management will respond to questions from stockholders.

Record Date; Quorum

Only holders of record of common stock at the close of business on April 5, 2016, the record date, will be entitled to vote at the meeting. At the close of business on April 5, 2016, we had 41,439,288 shares of common stock outstanding and entitled to vote.

The holders of a majority of the voting power of the shares of stock entitled to vote at the meeting as of the record date must be present at the meeting in order to hold the meeting and conduct business. This presence is called a quorum. Your shares are counted as present at the meeting if you are present and vote in person at the meeting or if you have properly submitted a proxy.

Voting Rights; Required Vote

Each holder of shares of common stock is entitled to one vote for each share of common stock held as of the close of business on April 5, 2016, the record date. You may vote all shares owned by you as of April 5, 2016, including (1) shares held directly in your name as the stockholder of record, and (2) shares held for you as the beneficial owner in street name through a broker, bank, trustee, or other nominee. On April 5, 2016, we had 41,439,288 shares of common stock issued and outstanding.

Stockholder of Record: Shares Registered in Your Name.    If on April 5, 2016 your shares were registered directly in your name with our transfer agent, Computershare, then you are considered the stockholder of record with respect to those shares. As a stockholder of record, you may vote at the meeting or vote by telephone, or if you request or receive paper proxy materials by mail, by filling out and returning the proxy card on a timely basis as described below.

Beneficial Owner: Shares Registered in the Name of a Broker or Nominee.    If on April 5, 2016 your shares were held in an account with a brokerage firm, bank or other nominee, then you are the beneficial owner of the shares held in street name. As a beneficial owner, you have the right to direct your nominee on how to vote the shares held in your account, and it has enclosed or provided voting instructions for you to use in directing it on how to vote your shares. However, the organization that holds your shares is considered the stockholder of record for purposes of voting at the meeting. Because you are not the stockholder of record, you may not vote your shares at the meeting unless you request and obtain a valid proxy from the organization that holds your shares giving you the right to vote the shares at the meeting.

Table of Contents

The election of directors requires a plurality vote of the shares of our common stock present in person or by proxy at the Annual Meeting and entitled to vote thereon. “Plurality” means that the nominees who receive the largest number of votes cast “for” are elected as directors. As a result, any shares not voted “for” a particular nominee (whether as a result of stockholder abstention or a broker non-vote) will not be counted in such nominee’s favor and will have no effect on the outcome of the election. You may vote “for” or “withhold” on each of the nominees for election as a director.

The ratification of the appointment of PricewaterhouseCoopers LLP will be obtained if the number of votes cast “for” such proposal at the meeting exceeds the number of votes “against” such proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

The advisory vote on the compensation of our named executive officers, commonly referred to as a "Say-on-pay" vote, will not be binding on us, our board of directors or the compensation committee of the board. In addition, the "Say-on-pay" vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this Proxy Statement. Approval of the "Say-on-pay" vote, will be obtained if the number of votes cast “for” such proposal at the meeting exceeds the number of votes “against” such proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

Abstentions (shares present at the meeting and voted “abstain”) are not counted as votes "for" or "against" a particular proposal and, therefore, are counted for purposes of determining whether a quorum is present, and have no effect on the outcome of the matters voted upon. Broker non-votes occur when shares held by a broker for a beneficial owner are not voted either because (i) the broker did not receive voting instructions from the beneficial owner, or (ii) the broker lacked discretionary authority to vote the shares. Broker non-votes are counted for purposes of determining whether a quorum is present, but have no effect on the outcome of the matters voted upon. If your broker holds your shares in its name and you do not instruct your broker how to vote, your broker will only have discretion to vote your shares on “routine” matters. Where a proposal is not “routine,” a broker who has not received instructions from its clients does not have discretion to vote its clients’ uninstructed shares on that proposal. At our Annual Meeting, only the proposal regarding the ratification of the appointment of PricewaterhouseCoopers LLP is considered a routine matter. Absent direction from you, your broker will therefore not have discretion to vote on the election of directors and the “Say-on-pay” vote. Accordingly, we encourage you to provide voting instructions to your broker, whether or not you plan to attend the Annual Meeting.

Recommendations of the Board of Directors on Each of the Proposals Scheduled to be Voted on at the Meeting

The board of directors recommends that you vote FOR the Class I director named in this proxy statement (Proposal 1), FOR the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2016 (Proposal 2) and FOR the "Say-on-pay" vote (Proposal 3).

Voting Instructions; Voting of Proxies

If you are a stockholder of record, you may:

vote at the meeting—follow the instructions at www.virtualshareholdermeeting.com/PFPT (have your proxy in hand when you visit the website);

vote via telephone—in order to do so, please follow the instructions shown on your proxy card; or

vote by mail—if you request or receive a paper proxy card and voting instructions by mail, simply complete, sign and date the enclosed proxy card and return it before the meeting in the envelope provided.

Votes submitted by telephone or mail must be received by 11:59 p.m., Eastern Time, on May 25, 2016. Submitting your proxy, whether by telephone, or by mail if you request or received a paper proxy card, will not affect your right to vote in person should you decide to attend the meeting. If you are not the stockholder of record, please refer to the voting instructions provided by your nominee to direct it how to vote your shares. You may either vote "FOR" the nominee to the board of directors, or you may withhold your vote from such nominee. For any other matter to be voted on, you may vote "FOR" or "AGAINST" or "ABSTAIN" from voting. Your vote is important. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure that your vote is counted.

If a stockholder attends the meeting and votes his, her or its shares during the meeting via the voting instructions described at www.virtualshareholdermeeting.com/PFPT, then any previous votes that were submitted by such stockholder, whether by telephone or mail, will be superseded by the vote that such stockholder casts during the meeting. Further, if the

2

Table of Contents

shares are held of record by a broker and a stockholder wishes to vote at the meeting, he, she or it must obtain a proxy issued in his, her or its name from the record holder in accordance with the materials and instructions for voting provided by his, her or its broker.

All proxies will be voted in accordance with the instructions specified on the proxy card. If you sign a physical proxy card and return it without instructions as to how your shares should be voted on a particular proposal at the meeting, your shares will be voted in accordance with the recommendations of our board of directors stated above.

If you do not vote and you hold your shares in street name, and your broker does not have discretionary power to vote your shares, your shares may constitute "broker non-votes" (as described above) and will not be counted in determining the number of shares necessary for approval of the proposals. However, shares that constitute broker non-votes will be counted for the purpose of establishing a quorum for the meeting.

If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. To make certain all of your shares are voted, please follow the instructions included on each proxy card and vote each proxy card by telephone or at the meeting. If you requested or received paper proxy materials by mail, please complete, sign and return each proxy card on a timely basis as described above to ensure that all of your shares are voted.

Expenses of Soliciting Proxies

The expenses of soliciting proxies will be paid by Proofpoint. Following the original mailing of the soliciting materials, Proofpoint and its agents may solicit proxies by mail, electronic mail, telephone, facsimile, by other similar means, or in person. Our directors, officers, and other employees, without additional compensation, may solicit proxies personally or in writing, by telephone, email, or otherwise. Following the original mailing of the soliciting materials, Proofpoint will request brokers, custodians, nominees and other record holders to forward copies of the soliciting materials to persons for whom they hold shares and to request authority for the exercise of proxies. In such cases, Proofpoint, upon the request of the record holders, will reimburse such holders for their reasonable expenses. If you choose to access the proxy materials through the Internet, you are responsible for any Internet access charges you may incur.

Revocability of Proxies

A stockholder who has given a proxy may revoke it at any time before it is exercised at the meeting by:

delivering to the Corporate Secretary of Proofpoint (by any means, including facsimile) a written notice stating that the proxy is revoked;

signing and delivering a proxy bearing a later date;

voting again by telephone; or

attending and voting at the meeting (following the instructions at www.virtualshareholdermeeting.com/PFPT) (note that attendance at the meeting will not, by itself, revoke a proxy).

Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to revoke a proxy, you must contact that firm to revoke any prior voting instructions.

Attending the Meeting

You will be able to attend the Annual Meeting online, submit your questions during the meeting and vote your shares electronically at the meeting by visiting www.virtualshareholdermeeting.com/PFPT. To participate in the Annual Meeting online, you will need the control number included on your proxy card. The Annual Meeting webcast will begin promptly at 9:00 a.m. Pacific Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 8:55 a.m. Pacific Time.

Voting Results

Voting results will be tabulated and certified by the inspector of elections appointed for the meeting. The preliminary voting results will be announced at the meeting. The final results will be tallied by the inspector of elections and filed with the SEC in a current report on Form 8-K within four business days of the meeting.

BOARD OF DIRECTORS AND COMMITTEES OF THE BOARD; CORPORATE GOVERNANCE STANDARDS AND DIRECTOR INDEPENDENCE

Proofpoint is strongly committed to good corporate governance practices. These practices provide an important framework within which our board of directors and management can pursue our strategic objectives for the benefit of our stockholders.

Corporate Governance Guidelines

Our board of directors has adopted Corporate Governance Guidelines that set forth expectations for directors, director independence standards, board committee structure and functions, and other policies for the governance of the company. Our Corporate Governance Guidelines are available on the Investor section of our website, which is located at http://investors.proofpoint.com, by clicking on "Corporate Governance Guidelines," under "Corporate Governance." The Corporate Governance Guidelines are reviewed periodically by our nominating and corporate governance committee, and changes are recommended to our board of directors with respect to changes as warranted.

Board Leadership Structure

Our Corporate Governance Guidelines provide that our board of directors shall be free to choose its chairman in any way that it considers in the best interests of our company, and that the nominating and corporate governance committee shall periodically consider the leadership structure of our board of directors and make such recommendations related thereto to the board of directors with respect thereto as the nominating and corporate governance committee deems appropriate. Our Corporate Governance Guidelines also provide that, when the positions of chairman and chief executive officer are held by the same person, the independent directors shall designate a "lead independent director." In cases in which the chairman and chief executive officer are the same person, the chairman schedules and sets the agenda for meetings of the board of directors, and the chairman, or if the chairman is not present, the lead independent director chairs such meetings. The responsibilities of the chairman or, if the chairman and the chief executive officer are the same person, the lead independent director, include: presiding at executive sessions; serving as a liaison between the chairman and the independent directors, being available, under appropriate circumstances, for consultation and direct communication with stockholders; and facilitating communication between the independent directors and management.

Our board of directors believes that we and our stockholders currently are best served by having Eric Hahn, an independent director, serve as chairman. Separating the positions of chief executive officer and chairman allows our president and chief executive officer to focus on our day-to-day business, while allowing the chairman to lead our board of directors in its fundamental role of providing independent advice to and oversight of management. Our board of directors believes that its independence and oversight of management is maintained effectively through this leadership structure, the composition of the board of directors and sound corporate governance policies and practices.

Our Board of Directors' Role in Risk Oversight

Our board of directors, as a whole, has responsibility for risk oversight, although the committees of our board of directors oversee and review risk areas which are particularly relevant to them. The risk oversight responsibility of our board of directors and its committees is supported by our management reporting processes, which are designed to provide visibility to the board of directors and to our personnel that are responsible for risk assessment and information about the identification, assessment and management of critical risks and management's risk mitigation strategies. These areas of focus include, but are not limited to, competitive, economic, operational, financial (accounting, credit, liquidity, and tax), legal, regulatory, compliance and reputational risks.

Each committee of the board of directors meets in executive session with key management personnel and representatives of outside advisors to oversee risks associated with their respective principal areas of focus. The audit committee reviews our major financial risk exposures and the steps management has taken to monitor and control such exposures, including our risk assessment and risk management policies and guidelines. The compensation committee reviews risks and exposures associated with compensation programs and arrangements, including incentive plans. The nominating and corporate governance committee, together with the audit committee, reviews our major legal compliance risk exposures and monitors the steps management has taken to mitigate these exposures, including our legal risk assessment and legal risk management policies and guidelines.

Independence of Directors

4

Table of Contents


Our board of directors determines the independence of our directors by applying the independence principles and standards established by the NASDAQ Global Market. These provide that a director is independent only if the board affirmatively determines that the director has no direct or indirect material relationship with our company. They also specify various relationships that preclude a determination of director independence. Material relationships may include commercial, industrial, consulting, legal, accounting, charitable, family and other business, professional and personal relationships.

Applying these standards, the board annually reviews the independence of the company's directors, taking into account all relevant facts and circumstances. In its most recent review, the board considered, among other things, the relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.

Based upon this review, our board of directors has determined that the following members of our board of directors are currently independent as determined under the rules of the NASDAQ Global Market:

Eric Hahn
 
Jonathan Feiber
Anthony Bettencourt
 
Douglas Garn
Dana Evan
 
Kevin Harvey


All members of our audit committee, compensation committee, and nominating and corporate governance committee must be independent directors as defined by our Corporate Governance Guidelines. Members of the audit committee must also satisfy a separate SEC independence requirement, which provides that they may not accept directly or indirectly any consulting, advisory or other compensatory fee from Proofpoint or any of its subsidiaries other than their directors' compensation. No member of the audit committee may be a partner, member or principal of a law firm, accounting firm or investment banking firm that accepts consulting or advisory fees from Proofpoint or any of its subsidiaries. Our board of directors has determined that all members of our audit committee, compensation committee and nominating and corporate governance committee are independent and all members of our audit committee satisfy the relevant SEC additional independence requirements for the members of such committee.

Committees of Our Board of Directors

Our board of directors has established an audit committee, a compensation committee, mergers and acquisitions committee and a nominating and corporate governance committee. The composition and responsibilities of each committee are described below. Copies of the charters for the audit committee, the compensation committee, and the nominating and corporate governance committee are available, without charge, upon request in writing to Proofpoint, Inc., 892 Ross Drive, Sunnyvale, California 94089, Attn: General Counsel or by clicking on "Corporate Governance" in the Investor section of our website, http://investors.proofpoint.com. Members serve on these committees until their resignations or until otherwise determined by our board of directors.

Audit Committee

Mr. Bettencourt was appointed to our audit committee in April 2015 after Ms. Carey resigned as a member of our board of directors and our audit committee. The composition of our audit committee meets the requirements for independence under current NASDAQ Global Market and SEC rules and regulations. Each member of our audit committee is financially literate as required by current NASDAQ Global Market listing standards. In addition, our board of directors has determined that Ms. Evan is an audit committee financial expert within the meaning of Item 407(d) of Regulation S-K under the Securities Act of 1933, as amended. Our audit committee, among other things:

selects a qualified firm to serve as the independent registered public accounting firm to audit our financial statements;

Compensation Committee

Our compensation committee is comprised of Mr. Feiber, who is the chair of the compensation committee, Ms. Evan and Mr. Garn.

Each member of this committee is also a non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, and an outside director, as defined pursuant to Section 162(m) of the Code. The purpose of our compensation committee is to discharge the responsibilities of our board of directors relating to compensation of our executive officers. Our compensation committee, among other things:

administers our stock and equity incentive plans;

reviews and approves and makes recommendations to our board of directors regarding incentive compensation and equity plans; and

The compensation committee has the exclusive authority and responsibility to determine all aspects of executive compensation packages for executive officers and makes recommendations to our board of directors regarding the compensation of non-employee directors and the chief executive officer. The compensation committee may take into account the recommendations of the chief executive officer with respect to compensation of the other executive officers.

Nominating and Corporate Governance Committee

Our nominating and governance committee is comprised of Mr. Hahn, who is the chair of the nominating and governance committee, and Mr. Bettencourt and Mr. Harvey.

authorizes and approves the negotiation by the Company of proposed acquisitions by the Company of pre-approved threshold values; and

Compensation Committee Interlocks and Insider Participation

The members of our compensation committee during 2015 were Mr. Feiber, Ms. Evan and Mr. Garn. None of the members of our compensation committee in 2015 was at any time during 2015 or at any other time an officer or employee of Proofpoint or any of its subsidiaries, and none had or have any relationships with Proofpoint that are required to be disclosed under Item 404 of Regulation S-K. None of our executive officers has served as a member of our board of directors, or as a member of the compensation or similar committee, of any entity that has one or more executive officers who served on our board of directors or compensation committee during 2015.

Board and Committee Meetings and Attendance

The board of directors and its committees meet throughout the year on a set schedule, and also hold special meetings and act by written consent from time to time. During 2015, the board of directors met six (6) times, including telephonic meetings, the audit committee held meetings seven (7) times, the compensation committee met four (4) times, and the nominating and corporate governance committee held one (1) meeting. None of the directors attended fewer than 75% of the aggregate of the total number of meetings held by the board of directors and the total number of meetings held by all committees of the board of directors on which such director served (during the period which such director served).
 
Board Attendance at Annual Stockholders' Meeting

Our policy is to invite and encourage each member of our board of directors to be present at our annual meetings of stockholders. At our 2015 Annual Meeting of Stockholders, our chairman, Mr. Hahn, and Mr. Steele, attended the meeting.

Presiding Director of Non-Employee Director Meetings

The non-employee directors meet in regularly scheduled executive sessions without management to promote open and honest discussion. Our chairman, currently Mr. Hahn, is the presiding director at these meetings.

NOMINATIONS PROCESS AND DIRECTOR QUALIFICATIONS

Nomination to the Board of Directors

Candidates for nomination to our board of directors are selected by our board of directors based on the recommendation of the nominating and corporate governance committee in accordance with the committee's charter, our certificate of incorporation and bylaws, our Corporate Governance Guidelines, and the criteria adopted by the board of directors regarding director candidate qualifications. In recommending candidates for nomination, the nominating and corporate governance committee considers candidates recommended by directors, officers, employees, stockholders and others, using the same criteria to evaluate all candidates. Evaluations of candidates generally involve a review of background materials, internal discussions and interviews with selected candidates as appropriate and, in addition, the committee may engage consultants or third-party search firms to assist in identifying and evaluating potential nominees.

Additional information regarding the process for properly submitting stockholder nominations for candidates for membership on our board of directors is set forth below under "Stockholder Proposals to Be Presented at Next Annual Meeting."

Director Qualifications

With the goal of developing a diverse, experienced and highly-qualified board of directors, the nominating and corporate governance committee is responsible for developing and recommending to the board of directors the desired qualifications, expertise and characteristics of members of our board of directors, including the specific minimum qualifications that the committee believes must be met by a committee-recommended nominee for membership on the board of directors and any specific qualities or skills that the committee believes are necessary for one or more of the members of the board of directors to possess.

Since the identification, evaluation and selection of qualified directors is a complex and subjective process that requires consideration of many intangible factors, and will be significantly influenced by the particular needs of the board of directors from time to time, our board of directors has not adopted a specific set of minimum qualifications, qualities or skills that are necessary for a nominee to possess, other than those that are necessary to meet U.S. legal, regulatory and NASDAQ listing requirements and the provisions of our certificate of incorporation, bylaws, Corporate Governance Guidelines, and charters of the board committees. In addition, neither the board of directors nor the nominating and corporate governance committee has a formal policy with regard to the consideration of diversity in identifying nominees. When considering nominees, the nominating and corporate governance committee may take into consideration many factors including, among other things, a candidate's independence, integrity, skills, financial and other expertise, breadth of experience, and knowledge about our business or industry and ability to devote adequate time and effort to responsibilities of the board of directors in the context of its existing composition. Through the nomination process, the nominating and corporate governance committee seeks to promote board membership that reflects a diversity of business experience, expertise, viewpoints, personal backgrounds and other characteristics that are expected to contribute to the board of directors' overall effectiveness. The brief biographical description of each director set forth in Proposal 1 below includes the primary individual experience, qualifications, attributes and skills of each of our directors that led to the conclusion that each director should serve as a member of our board of directors at this time.

Equity Awards.    Our non-employee director equity compensation policy provides that each newly-elected or appointed non-employee director will be granted an initial stock option to purchase 25,000 shares of our common stock and, immediately following each annual meeting of our stockholders, each non-employee director will automatically be granted an additional equity grant of RSUs equivalent to $175,000 if the non-employee director has served continuously as a member of our board of directors for at least six months. Each initial stock option award will vest in equal annual installments over three years from the date of grant while each annual RSU award will vest in full on the earlier of the one-year anniversary of the date of grant or immediately prior to the first annual meeting of our stockholders to occur after the date of grant. Our non-employee director equity compensation policy also provides that a director can elect annually to receive the aforementioned initial stock award in the forms of RSUs, the annual RSU award in the form of stock options, and the annual board service fees in the form of stock options or RSUs. One-quarter of each stock option or RSU award provided in lieu of annual board service fees will vest upon the completion of each calendar quarter of board service, commencing with the second calendar quarter of the year or with the grant immediately after the annual meeting of our stockholders. Each of these stock option awards will be immediately exercisable in full; however, any unvested shares issued upon exercise will be subject to a right of repurchase by us upon termination of service, which right will lapse in accordance with the vesting schedule described above. Options granted to non-

PROPOSAL NO. 2
RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM


Our audit committee has selected PricewaterhouseCoopers LLP as Proofpoint's principal independent registered public accounting firm to perform the audit of Proofpoint's consolidated financial statements for fiscal year ending December 31, 2016. As a matter of good corporate governance, our audit committee has decided to submit its selection of principal independent registered public accounting firm to stockholders for ratification. In the event that PricewaterhouseCoopers LLP is not ratified by our stockholders, the audit committee will review its future selection of PricewaterhouseCoopers LLP as Proofpoint's principal independent registered public accounting firm.

PricewaterhouseCoopers LLP audited Proofpoint's financial statements for Proofpoint's 2015 fiscal year. Representatives of PricewaterhouseCoopers LLP are expected to be present at the meeting, in which case they will be given an opportunity to make a statement at the meeting if they desire to do so, and will be available to respond to appropriate questions.

Principal Accountant Fees and Services

We regularly review the services and fees from its independent registered public accounting firm. These services and fees are also reviewed with our audit committee annually. In accordance with standard policy, PricewaterhouseCoopers LLP periodically rotates the individuals who are responsible for Proofpoint's audit.

In addition to performing the audit of Proofpoint's consolidated financial statements, PricewaterhouseCoopers LLP provided various other services during fiscal 2014 and 2015. Our audit committee has determined that PricewaterhouseCoopers LLP's provisioning of these services, which are described below, does not impair PricewaterhouseCoopers LLP's independence from Proofpoint. The aggregate fees billed for fiscal 2014 and 2015 for each of the following categories of services are as follows:

PROPOSAL NO. 3
ADVISORY VOTE ON EXECUTIVE COMPENSATION

In accordance with the rules of the SEC, we are providing stockholders with a non-binding advisory vote on the compensation of our named executive officers as described below under the heading “Executive Compensation.” This non-binding advisory vote, commonly referred to as a “Say-on-pay” vote, gives our stockholders the opportunity to express their views on our named executive officers’ compensation as a whole. This vote is not intended to address any specific item of compensation, but rather the overall compensation of the named executive officers and the philosophy, policies and procedures described in this Proxy Statement.

Stockholders are urged to read the “Executive Compensation” section of this proxy statement, which discusses how our executive compensation policies and procedures implement our compensation philosophy and contains tabular information and narrative discussion about the compensation of our named executive officers. The compensation committee and the board of directors believe that these policies and procedures are effective in implementing our compensation philosophy and in achieving our goals. Accordingly, we are asking you to vote, on an advisory basis, which is non-binding, “FOR” the following resolution at the Annual Meeting:

"RESOLVED, that the compensation paid to Proofpoint, Inc.’s named executive officers, as disclosed pursuant to the Securities and Exchange Commission’s compensation disclosure rules, including the Compensation Discussion and Analysis, compensation tables and narrative discussion set forth in the Proxy Statement relating to its 2016 Annual Meeting of Stockholders, is hereby APPROVED."

As an advisory vote, this proposal is not binding. However, our board of directors and compensation committee, which is responsible for designing and administering our executive compensation program, value the opinions expressed by stockholders in their vote on this proposal, and will consider the outcome of the vote when making future compensation decisions.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DESCRIBED IN THE “EXECUTIVE COMPENSATION” SECTION OF THIS PROXY STATEMENT.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table presents the beneficial ownership of our common stock by one holder of more than 5% of our common stock, each of our directors or director nominees; each of our named executive officers; and all of our directors and executive officers as a group. Except for the information about the greater than 5% stockholder, the following table sets forth certain information with respect to the beneficial ownership of our common stock as of March 31, 2016, by each of our directors or director nominees; each of our named executive officers; and all of our directors, director nominees and executive officers as a group.

Percentage ownership of our common stock is based on 41,412,654 shares of our common stock outstanding on March 31, 2016. We have determined beneficial ownership in accordance with the rules of the SEC, and thus it represents sole or shared voting or investment power with respect to our securities. Unless otherwise indicated below, to our knowledge, the persons and entities named in the table have sole voting and sole investment power with respect to all shares that they beneficially owned, subject to community property laws where applicable. We have deemed shares of our common stock subject to options that are currently exercisable or exercisable within 60 days of March 31, 2016 to be outstanding and to be beneficially owned by the person holding the option for the purpose of computing the percentage ownership of that person but have not treated them as outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each of the individuals and entities named below that owns 5% or more of our common stock is c/o Proofpoint, Inc., 892 Ross Drive, Sunnyvale, California 94089.

In addition, we explain how and why the Compensation Committee of our Board of Directors arrived at the specific compensation policies and decisions involving the Named Executive Officers during 2015.

2015 Performance

Excellent Financial Performance

In 2015, we successfully executed our growth strategy and extended our leadership position in next-generation cybersecurity. Financial highlights for the year include:

Revenue:  Total revenue for 2015 was $265.4 million, an increase of 36%, compared to $195.6 million for 2014.

Billings:  Billings were $324.3 million for 2015, an increase of 39% compared to $233.7 million for 2014.

Gross Profit:  GAAP gross profit for 2015 was $181.3 million compared to $129.9 million for 2014.

Cash Flow:  We generated $45.5 million in net cash from operations during 2015 compared to generating $21.3 million during 2014. We generated $19.7 million in free cash flow during 2015 compared to $6.3 million during 2014.

Our total stockholder return ("TSR") continued to significantly outperform both the NASDAQ Composite Index and the NASDAQ Computer Index. Further, from our initial public offering in 2012 to the end of December 2015, our stock price has increased over 362%, significantly above the NASDAQ Composite Index (IXIC) returns over the same period.

Achievement of Significant Operational Milestones

Completed two strategic acquisitions: Emerging Threats, a leading provider of advanced threat intelligence, enhancing our current threat detection intelligence and responsiveness, and Socialware, a leader in social media compliance solutions, expanding our Nexgate product family. Both of these acquisitions extend and enhance our existing product capabilities and create additional value for our customers.

Grew our penetration in the Fortune 1000 by roughly 22% (from 231 customers at the close of 2014, to 282 at the close of 2015).

Grew international revenue by 24%.

CEO Pay-for-Performance

Objectives

Our steady and consistent growth since inception, is a direct correlation to the exceptional leadership of our CEO. His focus, creativity and ability to continually motivate our workforce have been instrumental in our success. Most significantly, his recognized status as a leader in next-generation cyber security has allowed us to attract and develop a high-caliber executive team, capable of achieving our long-term growth initiatives.

We believe it is critical to our continued success to offer our CEO a total compensation package that will, among other things:

1.     motivate and reward the achievement of our annual and long-term financial and strategic initiatives;

2.     ensure he remains with Proofpoint to guide our business so that we emerge as one of the leaders in the next-generation security and compliance market sector; and

3.     align his total compensation with stockholder performance.

Compensation

To achieve these objectives, in 2015 the Compensation Committee approved a target total direct compensation mix for our CEO which included base and variable compensation in the form of cash bonus and equity awards. The equity mix consisted of stock options, Restricted Stock Units (RSUs) and Performance Stock Units (PSUs). All elements of compensation were reviewed independently to warrant merit on their own, and as a whole to ensure a balanced total direct compensation package.

The Compensation Committee believes our CEO's total direct compensation opportunity is aligned with our performance. Over time, as the size, complexity and performance of Proofpoint has grown, the Compensation Committee has adjusted the target total direct compensation opportunity of our CEO to reflect his enhanced role and performance; and his tenure with the organization. The Compensation Committee views bonus compensation and equity awards as strong performance-based compensation vehicles. We recognize the creation of stockholder value and Company growth provide important context for

22

Table of Contents

understanding and evaluating the overall appropriateness of our CEO's total direct compensation. Further, our Board of Directors uses key financial measures to evaluate the continued growth and long-term market success of our business.


Executive Compensation Best Practices

In discharging its responsibilities relating to executive compensation, the Compensation Committee looks to enhance the effectiveness of our executive compensation program on an ongoing basis. As a result, our executive compensation program reflects the following policies and practices:

Independence—The Compensation Committee is composed solely of independent directors and has engaged its own independent compensation consultant.

Compensation-Related Risk Assessment—We evaluate our compensation programs, policies and practices to ensure that they reflect an appropriate level of risk-taking to further the growth of the business; but do not encourage our employees to take excessive or unnecessary risks that could have an adverse impact on the company.

Limited Change in Control Benefits—We do not provide for cash payments to our executive officers in the event of a change in control and provide for acceleration of unvested equity awards only in the event of (i) an involuntary termination of employment (ii) following a change in control (a so-called "double trigger" arrangement).

Limited Executive Perquisites—We do not provide any significant perquisites or other personal benefits to our executive officers; our executive officers participate in our health and welfare benefit programs on the same basis as all of our employees.

Retirement Programs—Other than our 401(k) retirement plan generally available to all employees, we do not provide defined benefit or contribution retirement plans or arrangements or nonqualified deferred compensation plans or arrangements for our executive officers.

Prohibition on Hedging—Under our insider trading policy, all employees (including our CEO and our named executive officers) and the non-employee members of our Board of Directors are prohibited from speculating in our equity securities, including the use of short sales, "sales against the box" or any equivalent transaction involving our equity securities. In addition, they may not engage in any other hedging transactions, such as "cashless" collars, forward sales, equity swaps and other similar or related arrangements, with respect to the securities that they hold. Additionally, under our insider trading policy, no employee or member of our Board of Directors may acquire, sell or trade in any interest or position relating to the future price of our equity securities.

No Tax "Gross-Ups" or Payments—We do not provide any "gross-ups" or tax payments in connection with any compensation element or any excise tax "gross-up" or tax reimbursement in connection with any change in control payments or benefits.

Performance Based Stock Program—We introduced a Performance Based Stock Program designed to incent our executive officers to drive long term financial and operational performance over a four year measurement period. The PSUs are earned based on our achievement of target levels linked to our financial and operational performance. Milestones have been established and are achieved when we have five consecutive quarters of year over year revenue growth and have achieved our pre-established profitability target level.

Executive Compensation Philosophy and Objectives

The cyber security and compliance industry is a dynamic and highly competitive business environment, which is characterized by frequent technological advances, rapidly changing market requirements, and the emergence of new market entrants. To successfully grow our business in this dynamic environment, we must continually develop and refine our solutions to stay ahead of customer needs and challenges. To achieve these objectives, we require a talented, accomplished and progressive team of technical, sales, marketing, operations, and other business professionals.

We compete with many other companies in seeking to attract and retain a skilled management team. To meet this challenge, we have embraced a compensation philosophy of offering our executive officers competitive total direct compensation opportunities that recognize and reward individual performance and contributions to our success. This allows us to attract, retain, and motivate talented executive officers with the skills and abilities needed to drive our desired business results through short-term and long-term compensation vehicles.

The specific objectives of our executive compensation program are to:

reward the successful achievement of our financial and strategic objectives;

drive the development of a successful and profitable business;

support the alignment of executive officer and stockholder interests by rewarding the achievement of company goals and the building of stockholder value;

attract, motivate, reward, and retain highly-qualified executive officers who are important to our success; and

recognize strong performers by offering compensation that rewards individual achievement as well as contributions to our overall success.

Compensation Program Design

Our executive compensation consists of base salary, an annual cash bonus opportunity and equity awards in the form of stock options, RSUs and PSUs.

The key component of our executive compensation program continues to be equity awards. As a public company, we emphasize the use of equity to provide incentives for our executive officers to focus on the growth of our overall enterprise value and, correspondingly, to create value for our stockholders. This equity compensation reflects a balanced mix of stock options, RSUs and PSUs (one-third stock options, one-third RSUs and one-third PSUs) based on value. The guidelines for each equity award were developed based on a blend of grant value and value as a percentage of market capitalization. The Compensation Committee continues to believe the combination of the three vehicles aligns our executive officers' total direct compensation opportunity to company performance. In 2015, we introduced PSUs as a component of the equity mix for our executive officers, including the Named Executive Officers. Going forward, we may introduce other forms of stock-based awards into our executive compensation program to offer our executive officers additional types of long-term equity incentives that align their interests with the long-term interests of our stockholders.

The PSU awards are designed to incent our executive officers to drive long term financial and operational performance over a four year measurement period. The PSUs are earned based on our achievement of target levels linked to our financial and operational performance. Milestones have been established and are achieved when we have five consecutive quarters of year over year revenue growth and have achieved our pre-established profitability target level.

We also provide cash compensation in the form of base salaries and annual cash bonus opportunities. Typically, we have structured our annual cash bonus opportunities to focus on the achievement of specific short-term financial and strategic objectives that will further our longer-term growth objectives.

24

Table of Contents


On an annual basis, the Compensation Committee reviews our compensation philosophy and programs and in general, we review executive compensation annually. As part of this review process, they consider the levels of compensation we would be willing to pay to ensure compensation remains competitive and that we are meeting our retention objectives, while also evaluating the cost to us if we were required to find a replacement for a key executive or employee.

We have used industry surveys, including data from the Radford Global Technology Compensation Survey, particularly for public companies with annual revenue of $75 million to $300 million, to assist the Compensation Committee in establishing cash compensation levels for our executive officers with an emphasis on technology companies of similar size, stage of development, and growth potential. We also use information from a compensation peer group as approved annually by the Compensation Committee. Using this information as a reference, the Compensation Committee has emphasized remaining competitive in our market and differentiating total cash compensation levels through the use of an annual cash bonus plan.

We have not adopted any formal policies or guidelines for allocating compensation between current and long-term compensation, between cash and non-cash compensation, or among different forms of non-cash compensation. Instead, the Compensation Committee reviews each component of executive compensation separately and also takes into consideration the value of each executive officer's compensation package as a whole and its relative size in comparison to our other executive officers.

Compensation-Setting Process

Role of the Compensation Committee

The Compensation Committee is responsible for evaluating, approving, and reviewing the compensation arrangements, plans, policies, and practices for our executive officers, including the Named Executive Officers (other than our CEO), and overseeing our cash and equity-based compensation plans. In the case of our CEO's cash compensation and equity awards, decisions are made by the independent members of our Board of Directors.

At the beginning of each year, the Compensation Committee, after consulting with management, establishes the applicable corporate performance objectives for our incentive compensation plans and makes decisions with respect to any base salary adjustment, approves certain individual performance objectives and target annual cash bonus opportunities. Recommendations for equity awards to our CEO continue to be developed by the Compensation Committee and submitted to the independent members of our Board of Directors for their consideration and approval. After the end of the fiscal year, the Compensation Committee reviews the performance of our executive officers, including the Named Executive Officers, to determine the payouts for the annual cash bonus opportunities for the previous year.

Role of Management

In carrying out its responsibilities, the Compensation Committee works with members of our management, including our CEO. Typically, our management assists the Compensation Committee by providing information on corporate and individual performance, competitive market data, and management's perspective and recommendations on compensation matters. Typically this information includes an analysis of our executive officers' compensation mix and levels compared to the competitive market (as determined using compensation survey data) prepared by our Human Resources Department or the compensation consultant to the Compensation Committee. The Compensation Committee then uses this information as one factor in its deliberations on specific compensation actions and decisions.

While the Compensation Committee solicits and reviews our CEO's recommendations and proposals with respect to compensation-related matters, the Compensation Committee only uses these recommendations and proposals as one factor in making compensation decisions.

Role of Compensation Consultant

The Compensation Committee is authorized to retain advisors from time to time, as it sees fit, in connection with carrying out its duties. Pursuant to that authority, the Compensation Committee engaged an independent compensation consultant, Compensia, Inc. ("Compensia"), to provide advice and ongoing recommendations on executive compensation matters for 2015.

Compensia representatives meet with our Compensation Committee during its regular meetings without any members of management present. Compensia with the acknowledgment and consent of the Compensation Committee also works with our management from time to time to assist it in the preparation of its recommendations for the Compensation Committee.

25

Table of Contents


Based on the consideration of the various factors as set forth in the listing standards of the NASDAQ Stock Market, the Compensation Committee does not believe that its relationship with Compensia and the work of Compensia on behalf of the Compensation Committee has raised any conflict of interest.

Use of Competitive Data

To assess the competitiveness of our executive compensation program and to assist it in setting compensation levels, the Compensation Committee refers to standard industry surveys, including the custom Radford Global Technology Compensation Survey and relevant peer company data. While the Compensation Committee reviews this compensation data to inform its decision-making process, it did not set compensation components to meet specific benchmarks. Instead, the Compensation Committee used this data as a point of reference so that it could set total compensation levels that it believed were reasonably competitive. While compensation levels differed among our executive officers based on competitive factors, and the role, responsibilities, and performance of each specific executive officer, there were no material differences in the compensation policies and practices for our executive officers, including the Named Executive Officers.

In August 2014, the Compensation Committee reviewed the peer group of companies it had used and removed certain companies because they had been acquired, or because they were no longer regarded as a peer due to poor revenue or market performance, and included additional companies that the Compensation Committee believed to more comparable to our current business.

This peer group was developed based on using the following criteria:

Revenue: ~0.5x to ~2.0x our then trailing four-quarter revenues of $150M
Preference of companies with strong revenue growth
Market Capitalization: ~0.33x to ~3.0x our market capitalization
Industry: SaaS security software and networking companies (primary); broad software (secondary)

This peer group was comprised of the following companies:

Barracuda Networks, Inc.
 
Jive Software, Inc.
Bazaarvoice, Inc.
 
LogMeIn, Inc.
Bottomline Technologies, Inc.
 
Marketo, Inc.
BroadSoft, Inc.
 
MobileIron, Inc.
Constant Contact, Inc.
 
Qualys, Inc.
Cornerstone OnDemand, Inc.
 
The Ultimate Software Group, Inc.

VASCO Data Security International, Inc.
Ellie Mae, Inc.
 
Zendesk, Inc.
FireEye, Inc.
 
 
Gigamon, Inc.
 
 
Imperva, Inc.
 
 
Infoblox, Inc.
 
 

Executive Compensation Program Components

The following describes each component of our executive compensation program, the rationale for each, and how compensation amounts and awards are determined.

Base Salary

Base salary is the primary fixed component of our executive compensation program. We use base salary to compensate our executive officers, including the Named Executive Officers for services rendered during the year, and to ensure that we remain competitive in attracting and retaining executive talent. The Compensation Committee conducts an annual review of each executive officer's base salary and makes adjustments as it determines to be reasonable and necessary to reflect the scope

26

Table of Contents

of an executive officer's performance, contributions, responsibilities, experience, prior salary level and position (in the case of a promotion), and market conditions.

In January 2015, the Compensation Committee reviewed the base salaries of our executive officers, including the Named Executive Officers, taking into consideration a compensation analysis performed by Compensia and the base salary recommendations of our CEO (except with respect to his own base salary), as well as the other factors described above. The Compensation Committee determined to increase Mr. Knight's annual base salary of 12% to strengthen alignment with the peer group market practices and our compensation philosophy of 50th to 75th percentile, and to recognize the Information Security Product Group's performance and contribution to our overall business success, and decided to not adjust the annual base salaries of the other Named Executive Officers.

The base salaries of the Named Executive Officers for 2015 were as follows:

Annual Cash Bonuses
    
We use cash bonuses to motivate our executive officers, including the Named Executive Officers, to achieve our annual financial and operational objectives directly linked to our longer-term growth and success. At the beginning of each year, the Compensation Committee

Approves target annual cash bonus opportunities for our executive officers

Selects one or more corporate financial and operational measures and related target levels based on our annual operating plan

Establishes the target bonus pool based on the pre-established measures


2015 Executive Bonus Plan

In January 2015, the Compensation Committee approved the corporate performance measures and related target levels for our 2015 Executive Bonus Plan for purposes of providing annual cash bonus opportunities to our executive officers, including the Named Executive Officers.

Target Annual Cash Bonus Opportunities

Under our Executive Bonus Plan, the target annual cash bonus opportunities are designed to reward our executive officers based on our overall company performance and each individual executive officer's contribution to performance. They are also aligned to market to ensure a competitive and retentive total cash compensation package. As in prior years, the Compensation Committee determined that the target annual cash bonus opportunities for each executive officer should be determined as a percentage of such executive officer's base salary. In January 2015, the Compensation Committee determined to make no adjustments to target annual cash bonus opportunities for the Named Executive Officers. The Compensation Committee believed the current target annual cash bonus opportunities were aligned with competitive market practices and peer group target opportunities and continue to deliver total cash compensation opportunities that were market competitive. The target

annual cash bonus opportunities for the Named Executive Officers for 2015 were:

Under the Executive Bonus Plan, our executive officers were permitted to elect to receive their 2015 bonus payout in the form of restricted stock awards. In the event of such an election, an executive officer would receive an award equal to 115% of his or her bonus amount. Any such awards vest on the first anniversary of the date of grant.

Corporate Performance Measures

Under the Executive Bonus Plan, the Compensation Committee selected revenue and Adjusted EBITDA as the two corporate performance measures to be used to fund the 2015 bonus pool. "Adjusted EBITDA" is defined in our periodic reports filed with the SEC. The Compensation Committee believed that the target levels for these two performance measures for 2015 would require a focused effort by management to achieve both levels of performance. For 2015, we achieved $265.4 million in revenue, which is approximately 105% of our annual revenue target for the Executive Bonus Plan. Our Adjusted EBITDA for the year 2015 was $4.6 million, which was approximately 271% of our Adjusted EBITDA target for the year.

Individual Performance Measures

To achieve our compensation objective of rewarding individual performance, our CEO developed a series of performance objectives for our Named Executive Officers (other than himself), which he deemed to be integral to the achievement of the corporate performance objectives and strengthen our internal operations. In addition, the Compensation Committee determined the individual performance objectives for our CEO.

For purposes of 2015 the Executive Bonus Plan, these performance objectives for the Named Executive Officers were as follows:

Mr. Steele - his performance objectives related to achieving externally-communicated revenue and billings, free cash flow, and gross margin targets, staffing recruitment and development, sales team productivity, inorganic growth and geographic revenue mix;

Mr. Auvil - his performance objectives related to the public reporting process and associated statutory filings, investor relations, continued cost reductions, and continued forecasting and reporting process improvements;

Mr. Knight - his performance objectives related to product positioning, sales enablement, service delivery and revenue delivery;

Mr. Lee - his performance objectives related to product enhancement, revenue delivery, and gross margin;

Ms. Newell - her performance objectives related to sales team productivity, quota-carrying sales capacity, sales leadership recruitment and hiring and international revenue.

At the end of the year, each executive officer's individual performance was evaluated by our CEO, who then made recommendations to the Compensation Committee with respect to the individual performance attainment percentage. In the case of our CEO, the independent members of the Board of Directors evaluated his individual contributions towards the achievement of his performance objectives.

Award Decisions and Analysis

In January 2016, the Compensation Committee evaluated our performance for 2015 and determined the attainment of the target bonus opportunity and resulting target payment to be paid to the Named Executive Officers for 2015. In making these

28

Table of Contents

awards, the Compensation Committee consulted with our CEO with respect to the Named Executive Officers (except with respect to his own bonus) and evaluated our financial and operational performance and the level of achievement of the corporate performance objectives for the year. The Compensation Committee determined that performance against target (Revenue and Adjusted EBITDA) for 2015 would result in a bonus pool of 107.5%.

Our CEO evaluated the achievement of each executive officer against his individual performance objectives and formulated a recommendation for each such executive officer's annual bonus for consideration by the Compensation Committee. These recommendations were based on his subjective assessment of each individual's contributions against their personal performance objectives during the year. In the case of our CEO, the independent members of the Board of Directors evaluated his performance against his individual performance objectives and determined the amount of his annual bonus. Mr. Steele was determined to have satisfied his performance objectives at a level of 94%. Mr. Auvil was determined to have satisfied his personal performance objectives at a level of 98%. Ms. Newell was determined to have satisfied her personal performance objectives at a level of 95%. Mr. Knight was determined to have satisfied his personal performance objectives at a level of 94%. Mr. Lee was determined to have satisfied his personal performance objectives at a level of 96%.

Based on these determinations, the Compensation Committee approved cash bonuses based on pro-rated base salaries to account for salary increases for the Named Executive Officers as follows:

We use equity awards to incent and reward our Named Executive Officers, for long-term corporate performance based on the value of our common stock and, thereby, to align the interests of our executive officers with those of our stockholders. These equity awards have been granted in the form of options to purchase shares of our common stock and in the form of both time-based and performance based restricted stock units. We believe that an appropriate mix of stock options, when granted with exercise prices equal to the fair market value of our common stock on the date of grant, and RSU and PSU awards allow us to compete effectively in the current market and provide an appropriate long-term incentive for our executive officers, since the stock options reward them only to the extent that our stock price grows and stockholders realize value following their grant date of the awards.

2015 Equity Awards

On January 28, 2015, the Compensation Committee approved equity awards for our Named Executive Officers. These 2015 equity awards consisted of a mix of stock options, RSUs and PSUs. The target award for each equity vehicle was established based on a combination of grant value and value as a percentage of market capitalization. The combined value of the target award was then divided into thirds (1/3 stock options, 1/3 RSU awards and 1/3 PSU awards) to establish share guidelines for each executive position. The individual equity awards delivered were based on the executives' performance against their contributions, including each executive officer's individual performance for 2014, and an overall assessment of our financial performance in areas such as revenue, bookings, gross margin and cash flow. Additionally, on January 28, 2015, the Compensation Committee recommended the approval of our CEO's cash compensation and equity awards to the independent members of our Board of Directors. The Board of Directors approved the Compensation Committee’s recommendations, including the grant of equity awards for our CEO.

Table of Contents

On April 16, 2015, the Compensation Committee approved an additional grant of RSUs for Mr. Knight. This award was recommended by our CEO as the result of the overall performance of the Information Security Product Group in 2014 and the addition of an even broader product suite and responsibilities as the result of the strategic acquisition of Emerging Threats.

The size of the 2015 equity awards (excluding the additional equity award to Mr. Knight) was determined by the Compensation Committee (or independent members of our Board of Directors in the case of the CEO) and based on its evaluation of the annual competitive analysis prepared by Compensia, the Committee’s subjective assessment of the performance of our executive officers, their objectives to motivate and retain our executive officers and the relevant peer company market practices. Additionally, the Compensation Committee reviews equity award amounts from two perspectives; grant-date fair value and grant-date value as a percentage of market capitalization. We believe this approach allows for a more stable methodology on a year-over-year basis and ensures a more qualitative method to evaluate market values for equity and helps ensure we are granting equity awards in amounts that are market balanced and in line with our overall compensation philosophy.

The Compensation Committee then exercised its subjective judgment to set the value of the equity awards for each executive officer, taking into consideration its assessment of each individual's performance, the current equity holdings of each executive officer (with an emphasis on the remaining vesting requirements of any unvested holdings), the relative roles and responsibilities of each executive officer, and its desire to maintain parity in the awards granted to executive officers performing substantially similar responsibilities. In particular, in the case of the award for Mr. Auvil, the Compensation Committee considered his performance of his responsibilities as our principal financial executive with respect to his performance of this role in 2014, overall company financial performance in 2014, and his current total and future equity position. The Compensation Committee also noted that a new award would provide him with additional incentive to remain with the company for the next several years as we aim to expand our business as a public company. In the case of Ms. Newell, the Compensation Committee considered her performance of her responsibilities as our principal sales executive and with respect to her performance of this role in 2014, overall sales performance and productivity, company growth in 2014 and her current total and future equity position. Further, the Compensation Committee addressed the need to be competitive in the current market, and its expectations with respect to her performance of this role in 2015 and for the next several years as we aim to expand our business as a public company.

In the case of the award for Mr. Steele, the independent members of the Board of Directors considered his performance in all prior years and specifically in 2014. They considered the performance and growth of the business in 2014 and his efforts to develop our senior management team. The independent members of the Board of Directors also noted that, as the chief executive officer of a public company with a recent history of steady revenue growth and strong overall performance, his ability in moving us toward profitability, and his proven leadership in a growing industry sector, a meaningful equity award was appropriate to set his overall total direct compensation opportunity at approximately 75% of the median total direct compensation of chief executive officers of the companies in the compensation peer group.

Welfare and Other Benefits

We have established a 401(k) retirement plan for all employees who satisfy certain eligibility requirements, including requirements relating to age and length of service. We currently do not match any contributions made to the plan by our employees, including executive officers. We intend for the plan to qualify under Section 401(a) of the Internal Revenue Code so

30

Table of Contents

that eligible contributions by employees to the plan, and income earned on plan contributions, are not taxable to employees until withdrawn from the plan.

In addition, we provide other benefits to our executive officers, including the Named Executive Officers, on the same basis as all of our full-time employees in the country in which they are resident. These benefits include medical, dental, and vision benefits, medical and dependent care flexible spending accounts, short-term and long-term disability insurance, accidental death and dismemberment insurance, and basic life insurance coverage.

We design our employee benefits programs to be affordable and competitive in relation to the market, as well as compliant with applicable laws and practices. We adjust our employee benefits programs as needed based upon regular monitoring of applicable laws and practices and the competitive market.

Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide perquisites to our executive officers, except in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make our executive officers more efficient and effective, and for recruitment and retention purposes. During 2015, none of the Named Executive Officers received perquisites or other personal benefits that were, in the aggregate, $10,000 or more for each Named Executive Officer.

In the future, we may provide perquisites or other personal benefits in limited circumstances, such as where we believe it is appropriate to assist an individual executive officer in the performance of his or her duties, to make our executive officers more efficient and effective, and for recruitment, motivation, or retention purposes. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by the Compensation Committee or the independent members of the Board of Directors, as applicable.

Employment Agreements

We have entered into employment agreements with each of our executive officers, except as described below, which are comprised of an offer letter, an inventions assignment and confidentiality agreement, and an Arbitration Agreement. Our employment agreement with Mr. Steele is comprised solely of an offer letter and the Employee Confidentiality Agreement. Each of these arrangements was approved on our behalf by our Board of Directors or, in certain instances, the Compensation Committee. We believe that these employment offer letters were necessary to induce these individuals to forego other employment opportunities or leave their current employer for the uncertainty of a demanding position in a new and unfamiliar organization.

In filling these executive positions, our Board of Directors and the Compensation Committee, as applicable, was aware that it would be necessary to recruit candidates with the requisite experience and skills to manage a growing business in a unique market niche. Accordingly, it recognized that it would need to develop competitive compensation packages to attract qualified candidates in a dynamic labor market. At the same time, our Board of Directors and the Compensation Committee was sensitive to the need to integrate new executive officers into the executive compensation structure that it was seeking to develop, balancing both competitive and internal equity considerations.

Each of these employment offer letters provided for "at will" employment and sets forth the initial compensation arrangements for the executive officer, including an initial base salary, an annual cash bonus opportunity and/or a commissions plan, and an equity award in the form of a stock option to purchase shares of our common stock. The actual compensation of the executive officers may no longer be accurately reflected in the letters. Except for Ms. Newell, who has a severance arrangement (described below), these letters do not provide for any arrangements for payments or benefits upon termination of their employment in specified circumstances, including following a change in control (except the programmatic benefits inherent in any stock option award for the executives). These arrangements (including potential payments and terms) are discussed in more detail in the "—Potential Payments upon Termination or Change in Control" section below.

Outstanding Stock Options and Restricted Stock Units

For executive officers who have worked for our company one year or more prior to involuntary termination of employment, in the event that the employment of the executive officer is involuntarily terminated within 18 months following a change in control of our company, the unvested shares of our common stock subject to all of the outstanding stock options or restricted stock units previously granted to such executive officer will become immediately vested and exercisable in full, as described in "—Potential Payments Upon Termination or Change in Control." For executive officers who have worked for our company less than one year prior to involuntary termination, in the event that the employment of the executive officer is involuntarily terminated within 18 months following a change in control of our company, the shares of our common stock

31

Table of Contents

subject to the outstanding stock options or restricted stock units that are scheduled to be vested through the 12 month anniversary of the change of control event will become immediately vested and exercisable in full, as described in "—Potential Payments Upon Termination or Change in Control."

Objectives of Protections

We believe that these protections assisted us in attracting these individuals to join our company. We also believe that these protections serve our executive retention objectives by helping the Named Executive Officers maintain continued focus and dedication to their responsibilities to maximize stockholder value, including in the event that there is a potential transaction that could involve a change in control of our company. The terms of these agreements were determined after review by our Board of Directors or the Compensation Committee, as applicable, of our retention goals for each executive officer and an analysis of relevant market data.

For a summary of the material terms and conditions of these severance and change in control arrangements, see "Potential Payments Upon Termination or Change in Control" below.

Other Compensation Policies

Stock Ownership Guidelines

Currently, we have not implemented a policy regarding minimum stock ownership requirements for our executive officers, including the Named Executive Officers.

Compensation Recovery Policy

Currently, we have not implemented a policy regarding retroactive adjustments to any cash or equity-based incentive compensation paid to our executive officers and other employees where the payments were predicated upon the achievement of financial results that were subsequently the subject of a financial restatement. We intend to adopt a general compensation recovery (clawback) policy covering our annual and long-term incentive award plans and arrangements after the SEC adopts final rules implementing the requirement of Section 954 of the Dodd-Frank Act.

Derivatives Trading Policy

Our Insider Trading Policy prohibits the trading of derivatives or the hedging of our equity securities by our employees, including the Named Executive Officers, and directors.

Tax and Accounting Considerations

Deductibility of Executive Compensation

Section 162(m) of the Internal Revenue Code generally disallows public companies a tax deduction for federal income tax purposes of remuneration in excess of $1.0 million paid to the chief executive officer and each of the three other most highly-compensated executive officers (other than the chief financial officer) in any taxable year. Generally, remuneration in excess of $1.0 million may only be deducted if it is "performance-based compensation" within the meaning of the Code. In this regard, the compensation income realized upon the exercise of stock options granted under a stockholder-approved stock option plan generally will be deductible so long as the options are granted by a committee whose members are non-employee directors and certain other conditions are satisfied.

Where reasonably practicable, the Compensation Committee seeks to qualify the variable compensation paid to our executive officers for the "performance-based compensation" exemption from the deductibility limit. As such, in approving the amount and form of compensation for our executive officers in the future, we will consider all elements of the cost to our company of providing such compensation, including the potential impact of Section 162(m). In the future, the Compensation Committee may, in its judgment, authorize compensation payments that do not comply with an exemption from the deductibility limit when it believes that such payments are appropriate to attract and retain executive talent.

Taxation of Nonqualified Deferred Compensation

Section 409A of the Code requires that amounts that qualify as “nonqualified deferred compensation” satisfy requirements with respect to the timing of deferral elections, timing of payments, and certain other matters. Generally, the

32

Table of Contents

Compensation Committee intends to administer our executive compensation program and design individual compensation components, as well as the compensation plans and arrangements for our employees generally, so that they are either exempt from, or satisfy the requirements of, Section 409A. From time to time, we may be required to amend some of our compensation plans and arrangements to ensure that they are either exempt from, or compliant with, Section 409A.

Taxation of "Parachute" Payments

Sections 280G and 4999 of the Internal Revenue Code provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of our company that exceeds certain prescribed limits, and that our company (or a successor) may forfeit a deduction on the amounts subject to this additional tax. We did not provide any executive officer, including any Named Executive Officer, with a "gross-up" or other reimbursement payment for any tax liability that the executive officer might owe as a result of the application of Sections 280G or 4999 during 2015, and we have not agreed and are not otherwise obligated to provide any executive officer with such a "gross-up" or other reimbursement.

Accounting for Stock-Based Compensation

We follow ASC 718 for our stock-based compensation awards. ASC 718 requires companies to measure the compensation expense for all share-based payment awards made to employees and directors, including stock options, based on the grant date "fair value" of these awards. This calculation is performed for accounting purposes and reported in the compensation tables below, even though our executive officers may never realize any value from their awards. ASC 718 also requires companies to recognize the compensation cost of their stock-based compensation awards in their income statements over the period that an executive officer is required to render service in exchange for the option or other award.

Risk Assessment of Compensation Programs

We have determined that our compensation policies, plans and practices are appropriately balanced and do not create risks that are reasonably likely to have a material adverse effect on our company. To make this determination, our management reviewed the compensation policies, plans and practices for our executive officers, as well as for all other employees. We assessed the following features of our compensation, plans and practices: design, payment methodology, potential payment volatility, relationship to our financial results, length of performance period, risk-mitigating features, performance measures and goals, oversight and controls, and plan features and values compared to market practices. Based on this review, we believe that our compensation policies, plans and practices do not create risks that are reasonably likely to have a material adverse effect on our company.

Executive Compensation Tables

The following table provides information regarding all plan and non-plan compensation awarded to, earned by or paid to, our Chief Executive Officer, our Chief Financial Officer, and each of our three other most highly compensated executive officers serving as such at December 31, 2015 for all services rendered in all capacities to us during 2015.

(1)
The amounts in this column represent the aggregate grant date fair values of the stock options, RSUs and PSUs granted during the year indicated in the row, computed in accordance with FASB Accounting Standards Codification Topic 718.

(2)
The amounts in this row reflect, in dollar amounts, the threshold, target and maximum potential RSA awards for the 2015 Bonus Payout. Mr. Steele and Mr. Auvil, each has elected to receive their 2015 Bonus Payout in the form of equity (Restricted Stock Awards with a 100% vest date 12 months from date of grant) and as the result of their election, each received an additional 15% of their 2015 payout value in RSAs. Pursuant to the existing RSA agreements, in the event of a change in control of our company, if the Named Executive Officer has been employed by our company continuously for at least one year at the time of the change of control, then 100% of the then-unvested portion of each Named Executive Officer's RSAs will accelerate in full in the event of an involuntary termination of employment, as defined in the Named Executive Officer's RSA agreement, in connection with or within 18 months following a change in control of our company.

(3)
The amounts in this row reflect, in share amounts, the target and maximum potential PSUs for the performance period from January 1, 2015 through December 31, 2018. The 2015 PSU program did not contain any threshold value. These PSU awards vest over a four-year period as follows: 50% of the unvested PSUs will become eligible for vesting if, during the four-year period following the grant (the "Performance Period"), the Company (a) has had five consecutive quarters of year over year revenue growth exceeding the pre-defined target percentage and (b) has achieved certain profitability metrics per the Board-approved operating plan in each quarter over the same five quarter period. 100% of the unvested PSUs will become eligible for vesting if, during the Performance Period, the Company (a) has had five consecutive quarters of year over year revenue growth exceeding the pre-defined stretch target percentage and (b) has achieved certain profitability metrics per the Board-approved operating plan in each quarter over the same five quarter

period. Once PSUs are eligible for vesting, a pro rata portion (as measured against the Performance Period) of the amount eligible will vest subject to certification of the Compensation Committee, with the remainder to vest in pro rata portions annually over the Performance Period.

Unless otherwise noted in these footnotes, all stock options referenced in this table vest as to 25% of the shares of our common stock subject to the option on the first anniversary of the vesting commencement date, with the remainder of the shares vesting monthly in equal installments over the next three years.

(2)
Each of the options granted under the 2002 stock option/stock issuance plan was exercisable immediately upon grant, subject to our right to repurchase the unvested shares at the exercise price upon termination of the optionee's employment. The heading "unexercisable" with respect to grants that are marked with an asterisk refers to unvested shares that would still be subject to our right to repurchase upon termination of the optionee's employment if exercised.

Represents the fair market value of a share of our common stock, as determined by our Board of Directors or as determined by the closing market price, on the option's grant date. Please see "Management's Discussion and Analysis of Financial Condition and Results of Operation—Critical Accounting Policies—Stock-Based Compensation" of our annual report on Form 10-K for a discussion of how we have valued our common stock.

(4)
Pursuant to the existing option agreements, in the event of a change in control of our company, if the Named Executive Officer has been employed by our company continuously for at least one year at the time of the change of control, then 100% of the then-unvested portion of each Named Executive Officer's options will accelerate in full in the event of an involuntary termination of employment, as defined in the Named Executive Officer's option agreement, in connection with or within 18 months following a change in control of our company.

2015 Options Exercised and Stock Vested

The following table provides information regarding stock option exercises by our Named Executive Officers as of December 31, 2015, and the number of shares of restricted stock units held by each Named Executive Officer that vested during the 2015 fiscal year. Value realized on option exercise is calculated by subtracting the aggregate exercise price of the options exercised from the aggregate market value of the shares of common stock acquired on the date of exercise. Value realized on vesting of restricted stock unit awards is based on the fair market value of our common stock on the vesting date multiplied by the number of shares vested and does not necessarily reflect proceeds received by the Named Executive Officer.

Potential Payments upon Termination or Change of Control

We have entered into employment, termination of employment and change-in-control arrangements with our Named Executive Officers as summarized below:

Gary Steele.    Mr. Steele's initial offer letter no longer provides for any compensation in the event that he is terminated with or without cause. However, all of his equity compensation grants provide that if within 12 months following a change of control of Proofpoint we terminate his employment without cause or if Mr. Steele terminates his employment for good reason (including an adverse change in title, responsibility or authority, a relocation of employment location more than 50 miles from our current headquarters or a material reduction in base salary, provided that, Mr. Steele gives 90 days written notice of such occurrence and the Company has 30 days opportunity to cure), all then-unvested shares of equity (options, RSUs and performance-based RSUs) granted to Mr. Steele will fully vest on his termination date.

For purposes of Mr. Steele's equity compensation grants, a change of control includes (1) an acquisition of 50% or more of our outstanding voting stock by any person or entity; (2) a merger or consolidation of Proofpoint after which our then-current stockholders own less than a majority of the voting power of the surviving entity; (3) a sale of all or substantially all of our assets; or (4) similar change in control transaction.

The following table summarizes the potential payments and benefits payable to Mr. Steele upon termination of employment or a change in our control under each situation listed below, modeling, in each situation, that Mr. Steele was terminated on December 31, 2015.

For purposes of Mr. Auvil's equity compensation grants, a change of control includes (1) an acquisition of 50% or more of our outstanding voting stock by any person or entity; (2) a merger or consolidation of Proofpoint after which our then-current stockholders own less than a majority of the voting power of the surviving entity; (3) a sale of all or substantially all of our assets; or (4) similar change in control transaction.

Tracey Newell.    Ms. Newell's offer letter provide that if within 12 months following a change of control of Proofpoint we terminate her employment without cause or if Ms. Newell terminates her employment for good reason (including an adverse change in title, responsibility or authority, a relocation of employment location more than 50 miles from our current headquarters or a material reduction in base salary, provided that, Ms. Newell gives 90 days written notice of such occurrence and the Company has 30 days opportunity to cure), Ms. Newell will receive severance equal to 6 months of salary plus an amount equal to 6 months of Cobra premiums and all then-unvested shares of equity (options, RSUs and performance-based RSUs) granted to Ms. Newell will fully vest on her termination date.

We have also agreed that in the event we terminate Ms. Newell's employment without cause, or if Ms. Newell terminates her employment for good reason, Ms. Newell will receive 6 months' salary and equal to 6 months of Cobra premiums. Our obligation to make any severance payments is expressly conditioned upon Ms. Newell's execution and delivery of a general release and waiver of all claims.

In the event that a portion of the severance and other benefits provided to Ms. Newell under the offer letter or any other agreement, benefit, plan or policy of Proofpoint are subject to a specified federal excise tax in connection with a change of control, such severance and other benefits will be reduced on a pre-tax basis if such reduction would provide Ms. Newell with a greater amount of severance and other benefits on an after-tax basis.

For purposes of Ms. Newell's employment offer letter, a change of control includes (1) an acquisition of 50% or more of our outstanding voting stock by any person or entity; (2) a merger or consolidation of Proofpoint after which our then-current stockholders own less than a majority of the voting power of the surviving entity; (3) a sale of all or substantially all of our assets; or (4) similar change in control transaction.

The following table summarizes the potential payments and benefits payable to Ms. Newell upon termination of employment or a change in our control under each situation listed below, modeling, in each situation, that Ms. Newell was terminated on December 31, 2015. Ms. Newell's employment contract requires that the severance payment be paid in a lump sum.

RELATED PARTY TRANSACTIONS

Other than compensation arrangements, including employment, termination of employment and change of control arrangements and indemnification arrangements, discussed above in the section entitled "Executive Compensation," there are no transactions since January 1, 2015 or currently proposed transactions in which:

we have been or are to be a participant;

the amount involved exceeded or exceeds $120,000; and

any of our directors, executive officers or holders of more than 5% of our capital stock, or any immediate family member of or person sharing the household with any of these individuals, had or will have a direct or indirect material interest.

Review, Approval or Ratification of Transactions with Related Parties

Our board of directors has adopted a written related person transactions policy. Under this policy, the audit committee reviews transactions that may be "related-person transactions," which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. For purposes of the policy, a related person is a director, executive officer, nominee for director, or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed fiscal year, and their immediate family members.

This policy provides that, barring special facts or circumstances, a related person does not have a direct or indirect material interest in the following categories of transactions:

employment-related compensation to executive officers that is approved by the compensation committee;

compensation to non-employee directors that is approved by our board of directors and is required to be reported in our proxy statement;

transactions with another company at which (i) the related person's only relationship is as a beneficial owner of less than 10% of that company's shares or as a limited partner holding interests of less than 10% in that partnership; or (ii) the related person is a director (and his or her interest in the transaction arises solely from his or her position as a director of that company);

charitable contributions, grants or endowments by us to a charitable organization, foundation or university at which the related person's only relationship is as an employee (or at which the related person is a trustee, director or executive officer if the aggregate amount involved in our fiscal year does not exceed $300,000), or any non-discretionary matching contribution, grant or endowment made pursuant to a matching gift program;

transactions where the related person's interest arises solely from the ownership of publicly traded securities issued by us and all holders of those securities receive proportional benefits;

ordinary course business travel and expenses, advances and reimbursements; and

payments made pursuant to (i) directors and officers insurance policies, (ii) our certificate of incorporation or bylaws, and/or (iii) any policy, agreement or instrument previously approved by our board of directors, such as indemnification agreements.

When transactions involving related persons do not fall into one of the above categories, they will be reviewed by our disclosure committee. The disclosure committee determines whether a related person could have a significant interest in such a transaction, and any such transaction is referred to the audit committee. Transactions may also be identified through our code of business conduct and ethics or other policies and procedures and reported to the audit committee. The audit committee will review the material facts of all related person transactions and either approve, disapprove, ratify, rescind, or take other appropriate action (in its discretion) with respect to the transaction.

The Audit Committee has reviewed and discussed with Proofpoint's management and PricewaterhouseCoopers, LLP the audited consolidated financial statements of Proofpoint for the year ended December 31, 2015. The Audit Committee has also discussed with PricewaterhouseCoopers, LLP the matters required to be discussed by SAS No. 61, as amended (AICPA, Professional Standards, Vol. 1.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16 of the Exchange Act requires Proofpoint's directors, executive officers and any persons who own more than 10% of Proofpoint's common stock, to file initial reports of ownership and reports of changes in ownership with the SEC. Such persons are required by SEC regulation to furnish Proofpoint with copies of all Section 16(a) forms that they file.

"Householding"—Stockholders Sharing the Same Last Name and Address

The SEC has adopted rules that permit companies and intermediaries (such as brokers) to implement a delivery procedure called "householding." Under this procedure, multiple stockholders who reside at the same address may receive a single copy of our annual report and proxy materials unless the affected stockholder has provided contrary instructions. This procedure reduces printing costs and postage fees, and helps protect the environment as well.
This year, a number of brokers with account holders who are Proofpoint stockholders will be "householding" our annual report and proxy materials. A single set of annual report and other proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by contacting

To receive a separate copy of the proxy statement, proxy card, annual report and other proxy materials, you may write Proofpoint's Investor Relations department at 892 Ross Drive, Sunnyvale, California 94089, Attn: Investor Relations, or at http://investors.proofpoint.com/contactus.cfm.

Any stockholders who share the same address and currently receive multiple copies of Proofpoint's annual report and other proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record to request information about householding or Proofpoint's Investor Relations department at the address or telephone number listed above.
