Dear Stockholder:

The attached Notice of Annual Meeting of Stockholders and Proxy Statement contain details of the business to be conducted at the Annual Meeting.

Whether or not you attend the virtual Annual Meeting, it is important that your shares be represented and voted at the meeting. Therefore, I urge you to promptly vote and submit your proxy via the internet, by phone or by mail.

On behalf of the Board of Directors, I would like to express our appreciation for your support of and interest in Zscaler.

Sincerely,

Our pay practices align with our pay-for-performance philosophy and underscore our commitment to sound compensation and governance practices. We believe that organizations are still in the early stages of embracing cloud-based business solutions and adopting the security and networking solutions, including our products,platform, that are necessary to secure and manage cloud-based operations. To be successful in this emerging market, we believe that delivering growth and capturing market share are paramount. To that end, we have focused our compensation program on performance metrics that are key to achieving growth in each fiscal year. Since we strongly believe that establishing and meeting aggressive growth targets in both the short term and the long term is the best way to deliver sustained stockholder value in a highly competitive and emerging market, we are continuing to focus our performance metrics for our annual executive cash bonuses on achieving growth in each fiscal year but, for our long-term incentive equity compensation, we are shifting tofocus our performance metrics focused on multi-year annual recurring revenue ("ARR") growth targets.

Fiscal 20222023 was a strong year for us marked by significant achievement and growth across all of our key metrics. Fiscal 20222023 highlights were as follows:

From Zscaler’s inception, we have recognized the importance of values, ethics, and doing the right thing. Our ESG program, with oversight provided by the nominating and corporate governance committee, works to help strengthen practices across the companyCompany so that we can better meet the needs of our customers, investors, employees and communities. We believe a thoughtful, robust and deliberate ESG program will drive sustained value creation for these stakeholders. While our program continues to evolve and grow, our current priorities include:

The information provided in the “question and answer” format below addresses certain frequently asked questions but is not intended to be a summary of all matters contained in this Proxy Statement. Please read the entire Proxy Statement carefully before voting your shares.

Our board of directors is providing these proxy materials to you in connection with our board of directors’ solicitation of proxies for use at Zscaler’s virtual Annual Meeting, which will take place on January 13, 2023.5, 2024. Stockholders are invited to attend the virtual Annual Meeting and are requested to vote on the proposals described in this Proxy Statement.

There are three proposals scheduled to be voted on at the Annual Meeting:

At the time this Proxy Statement was mailed, our management and board of directors were not aware of any other matters to be presented at the Annual Meeting.

Our board of directors recommends that you vote:

Holders of our common stock at the close of business on November 14, 2022,13, 2023, the record dateRecord Date for the Annual Meeting (the “Record Date”), are entitled to notice of and to vote at the Annual Meeting. Each stockholder is entitled to one vote for each share of our common stock held as of the Record Date. As of the Record Date, there were 144,211,307148,323,448 shares of common stock outstanding and entitled to vote. Stockholders are not permitted to cumulate votes with respect to the election of directors. The shares you are entitled to vote include shares that are (1) held of record directly in your name and (2) held for you as the beneficial owner through a stockbroker, bank or other nominee.

The Annual Meeting will be a completely virtual meeting, which will be conducted via live audio webcast. You are entitled to participate in the annual meetingAnnual Meeting only if you were a holder of our common stock as of the close of business on November 14, 202213, 2023 or if you hold a valid proxy for the Annual Meeting.

To participate in the Annual Meeting, you will need the control number included on your Notice or proxy card. The live audio webcast will begin promptly at 1:00 p.m. Pacific Time on January 13, 2023.5, 2024. We encourage you to access the meeting prior to the start time. Online check-in will begin at 12:45 p.m. Pacific Time, and you should allow ample time for the check-in procedures.

If you encounter any difficulties accessing the Annual Meeting during the check-in or meeting time, please call the technical support number that will be posted on the Annual Meeting log-in page.

Proxies are solicited by and on behalf of our board of directors. The persons named in the proxy have been designated as proxy holders by our board of directors. When a proxy is properly dated, executed and returned, the shares represented by the proxy will

An abstention represents a stockholder’s affirmative choice to decline to vote on a proposal. If a stockholder indicates on its proxy card that it wishes to abstain from voting its shares, or if a broker, bank or other nominee holding its customers’ shares of record causes abstentions to be recorded for shares, these shares will be considered present and entitled to vote at the Annual Meeting. As a result, abstentions will be counted for purposes of determining the presence or absence of a quorum and will also count as votes against a proposal in cases where approval of the proposal requires the affirmative vote of a majority of the voting power of the issued and outstanding shares of common stock present in person or represented by proxy and entitled to vote at the Annual Meeting (e.g., Proposal No. 2). Abstentions will have no impact on the outcome of Proposal No. 1 as long as a quorum exists.

A broker non-vote occurs when a broker, bank or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the broker, bank or other nominee does not have discretionary voting power with respect to such proposal and has not received voting instructions from the beneficial owner of the shares. Broker non-votes will be counted for purposes of calculating whether a quorum is present at the Annual Meeting but will not be counted for purposes of determining the number of votes cast. Therefore, a broker non-vote will make a quorum more readily attainable but will not otherwise affect the outcome of the vote on any proposal.

A quorum is the minimum number of shares required to be present at the Annual Meeting for the meeting to be properly held under our bylaws and Delaware law. The presence (including by proxy) of a majority of the voting power of our common stock issued and outstanding and entitled to vote at the Annual Meeting will constitute a quorum at the Annual Meeting. As noted above, as of the Record Date, there were a total of 144,211,307148,323,448 shares of common stock outstanding, which means that 72,105,65474,161,725 shares of common stock must be represented at the Annual Meeting to have a quorum. If there is no quorum, the chairperson of the meeting or a majority of the voting power of our common stock present at the Annual Meeting may adjourn the meeting to a later date.

Our board of directors is soliciting proxies for use at the Annual Meeting by means of the proxy materials. We will bear the entire cost of proxy solicitation, including the preparation, assembly, printing, mailing and distribution of the proxy materials. Copies of solicitation materials will also be made available upon request to brokers, banks and other nominees to forward to the beneficial owners of the shares held of record by such brokers, banks or other nominees. The original solicitation of proxies may be supplemented by solicitation by telephone, electronic communication, or other means by our directors, officers, employees or agents. No additional compensation will be paid to these individuals for any such services, although we may reimburse such individuals for their reasonable out-of-pocket expenses in connection with such solicitation. We do not plan to retain a proxy solicitor to assist in the solicitation of proxies.

If you choose to access the proxy materials and/or vote over the internet, you are responsible for internet access charges you may incur. If you choose to vote by telephone, you are responsible for telephone charges you may incur.

If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each Notice to ensure that all of your shares are voted.

Proxy instructions, ballots and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within Zscaler or to third parties, except as necessary to meet applicable legal and administrative requirements, to allow for the tabulation of votes and certification of the vote, or to facilitate a successful proxy solicitation.

We have adopted an SEC-approved procedure called “householding.” Under this procedure, we will deliver only one copy of our Notice of Internet Availability of Proxy Materials (and for those stockholders that received a paper copy of proxy materials in the mail, one copy of our Annual Report to stockholders and this Proxy Statement) to multiple stockholders who share the same address (if they appear to be members of the same family), unless we have received contrary instructions from an affected stockholder. Stockholders who participate in householding will continue to receive separate proxy cards if they received a paper copy of proxy materials in the mail. This procedure reduces our printing and mailing costs. Upon written or oral request, we will promptly deliver a separate copy of the proxy materials and Annual Report to any stockholder at a shared address to which we delivered a single copy of any of these documents.

Stockholders who hold shares in street name may contact their broker, bank or other nominee to request information about householding.

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us at that time, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an amendment to the Form 8-K to publish the final results.

Our bylaws also establish an advance notice procedure for stockholders who wish to present a proposal before an annual meetingAnnual Meeting of stockholders but do not intend for the proposal to be included in our Proxy Statement. Our bylaws provide that the only business that may be conducted at an annual meetingAnnual Meeting is business that is (i) specified in our proxy materials with respect to such meeting, (ii) otherwise properly brought before the annual meetingAnnual Meeting by or at the direction of our board of directors, or (iii) properly brought

before the annual meetingAnnual Meeting by a stockholder of record entitled to vote at the annual meeting who has delivered timely written notice to our Secretary, which notice must contain the information specified in our bylaws. To be timely for our fiscal 20232024 Annual Meeting, our Secretary must receive the written notice at our principal executive offices:

In the event thatthe date we hold our fiscal 20232024 Annual Meeting has been changed by more than 30 days before or more than 60 days afterfrom the first anniversary of the date of the fiscal 20222023 Annual Meeting, then notice of a stockholder proposal that is not intended to be included in our Proxy Statement must be received no earlier than the close of business on the 120th day before the fiscal 20232024 Annual Meeting and no later than the close of business on the later of the following two dates:

If a stockholder who has notified us of his, her or its intention to present a proposal at an annual meeting does not appear to present his, her or its proposal at such annual meeting, we are not required to present the proposal for a vote at such annual meeting.

Our business affairs are managed under the direction of our board of directors, which is currently comprised of eight members. Six of our eight directors are independent within the meaning of the independent director requirements of the Nasdaq Stock Market LLC (“Nasdaq”). Our board of directors is divided into three classes with staggered three-year terms. At each annual meeting of stockholders, a class of directors will be elected for a three-year term to succeed the same class whose term is then expiring.

Upon the recommendation of our nominating and corporate governance committee, we are nominating Andrew Brown, Scott Darling, and David SchneiderJay Chaudhry as the sole Class II directorsIII director at the Annual Meeting. If elected, Messrs. Brown, Darling, and SchneiderMr. Chaudhry will each hold office for a three-year term until the 20252026 annual meeting of stockholders or until their successors arehis successor is elected and qualified. Amit Sinha, who is currently serving as one of our Class III directors, is not standing for re-election at the Annual Meeting, and his term will end upon the commencement of the Annual Meeting. We thank Mr. Sinha for his many years of service to the Company and our board of directors. The size of our board of directors will be automatically reduced to seven directors effective immediately upon the convening of the Annual Meeting.

The following table sets forth the names, ages as of November 1, 20222023 and certain other information for each of the directors with terms expiring at the Annual Meeting (who are also nominees for election as a director at the Annual Meeting) and for each of the continuing directors:

Our common stock is listed on the Nasdaq Global Select Market. Under the rules of Nasdaq, independent directors must comprise a majority of a listed company’s board of directors within a specified period after the completion of our initial public offering. In addition, the rules of Nasdaq require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and governance committees be independent. Audit committee members and compensation committee members must also satisfy the independence criteria set forth in Rule 10A-3 and Rule 10C-1, respectively, under the Exchange Act. Under the rules of Nasdaq, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

To be considered independent for purposes of Rule 10A-3 and under the rules of Nasdaq, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of our audit committee, our board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries; or (2) be an affiliated person of the listed company or any of its subsidiaries.

To be considered independent for purposes of Rule 10C-1 and under the rules of Nasdaq, the board of directors must affirmatively determine that the member of the compensation committee is independent, including a consideration of all factors specifically relevant to determining whether the director has a relationship to the company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: (i) the source of compensation of such director, including any consulting, advisory or other compensatory fee paid by the company to such director; and (ii) whether such director is affiliated with the company, a subsidiary of the company or an affiliate of a subsidiary of the company.

Our board of directors has undertaken a review of its composition, the composition of its committees and the independence of our directors and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our board of directors has determined that (i) none of Mses. Blasing and Naughton and Messrs. Brown, Darling, Giancarlo and Schneider, representing six of our eight directors has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and (ii) that each of these directors is “independent” as that term is defined under the rules of Nasdaq. Mr. Chaudhry and Dr. Sinha are not independent under Nasdaq’s independence standards. Our board of directors also determined that Ms. Blasing (chair) and Messrs. Brown and Darling, who comprise our audit committee, and Messrs. Brown (chair) and Giancarlo and Mses. Blasing and Naughton, who comprise our compensation committee, satisfy the independence standards for committee members established by applicable SEC rules and the listing standards of Nasdaq. Following the Annual Meeting, six of the seven directors will be independent.

There are no family relationships among any of our directors or executive officers.

Mr. Chaudhry currently serves as our Chief Executive Officer and Chairman of the Board. Our board of directors believes that the current board leadership structure, coupled with a strong emphasis on board independence, provides effective independent oversight of management while allowing the board and management to benefit from Mr. Chaudhry’s leadership, Company-specific experience and years of experience as an executive in the network security industry. Serving on our board of directors and as Chief Executive Officer since our founding in 2007, Mr. Chaudhry is best positioned to identify strategic priorities, lead critical discussion and execute our growth strategy and business plans. Mr. Chaudhry possesses detailed in-depth knowledge of the issues, opportunities and challenges facing us. The board of directors believes that Mr. Chaudhry’s combined role enables strong leadership, creates clear accountability and enhances our ability to communicate our message and strategy clearly and consistently to stockholders. The board of directors has not appointed a “lead independent director.” We believe that our board leadership structure is appropriate for our company,Company, particularly where we have a majority of independent directors who are all actively involved in board meetings.

In order to encourage and enhance communication among independent directors, and as required under the applicable rules of Nasdaq, our corporate governance guidelines provide that the independent directors of our board of directors will meet in executive sessions without management directors or Company management present on a periodic basis, but no less than twice a year.

During the fiscal year ended July 31, 2022,2023, our board of directors held four meetings (including regularly scheduled and special meetings), and each director attended at least 75% of the aggregate of (i) the total number of meetings of our board of directors held during the period for which he or she served as a director and (ii) the total number of meetings held by all committees of our board of directors on which he or she served during the periods that he or she served.

Although we do not have a formal policy regarding attendance by members of our board of directors at annual meetings of stockholders, we encourage, but do not require, our directors to attend. All of our then current serving directors attended our last year's annual meeting of stockholders.

None of the members of our compensation committee is or has been an officer or employee of the Company. None of our executive officers currently serves, or in the past year has served, as a member of the compensation committee or director (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of any entity that has one or more executive officers serving on our compensation committee or our board of directors.

It is the policy of the nominating and corporate governance committee of our board of directors to consider recommendations for candidates to our board of directors from stockholders holding no less than one percent (1%) of the outstanding shares of the Company’s common stock continuously for at least 12 months prior to the date of the submission of the recommendation or nomination.

The nominating and corporate governance committee will use the following procedures to identify and evaluate any individual recommended or offered for nomination to our board of directors:

If the nominating and corporate governance committee determines that an additional or replacement director is required, the nominating and corporate governance committee may take such measures that it considers appropriate in connection with its evaluation of a director candidate, including candidate interviews, inquiry of the person or persons making the recommendation or nomination, engagement of an outside search firm to gather additional information, or reliance on the knowledge of the members of the nominating and corporate governance committee, our board directors or management.

The nominating and corporate governance committee may propose to our board of directors a candidate recommended or offered for nomination by a stockholder as a nominee for election to our board of directors. The nominating and corporate governance committee has in the past and may in the future pay fees to third parties to assist in identifying or evaluating director candidates.

A stockholder that wants to recommend a candidate for election to our board of directors should direct the recommendation in writing by letter to the Company, attention of the Secretary, at Zscaler, Inc., 120 Holger Way, San Jose, California 95134. The recommendation must include the candidate’s name, home and business contact information, detailed biographical data, relevant qualifications, a signed letter from the candidate confirming willingness to serve, information regarding any relationships between the candidate and the Company and evidence of the recommending stockholder’s ownership of Company stock. Such recommendations must also include a statement from the recommending stockholder in support of the candidate, particularly within the context of the criteria for board membership, including issues of character, integrity, judgment, diversity of experience, independence, area of expertise, corporate experience, length of service, potential conflicts of interest, other commitments and the like and personal references.

A stockholder that instead desires to nominate a person directly for election to our board of directors at an annual meeting of the stockholders must meet the deadlines and other requirements set forth in Section 2.4 of the Company’s bylaws and the rules and regulations of the Securities and Exchange Commission. Section 2.4 of the Company’s bylaws requires that a stockholder who seeks to nominate a candidate for director must provide a written notice to the Secretary of the Company not later than the 45th day nor earlier than the 75th day before the one-year anniversary of the date on which the corporation first mailed its proxy materials or a notice of availability of proxy materials (whichever is earlier) for the preceding year’s annual meeting; provided, however, that in the event that no annual meeting was held in the previous year or if the date of the annual meeting is advancedchanged by more than 30 days prior to or delayed by more than 60 days afterfrom the one-year anniversary of the date of the previous year’s annual meeting, then, for notice by the stockholder to be timely, it must be so received by the secretary not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of (i) the 90th day prior to such annual meeting, or (ii) the 10th day following the day on which Public Announcement (as defined below) of the date of such annual meeting is first made. In no event shall any adjournment or postponement of an annual meeting or the announcement thereof commence a new time period for the giving of a stockholder’s notice. “Public Announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or a comparable national news service or in a document publicly filed by the corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act, or any successor thereto.by such other means as is reasonably designed to inform the public or stockholders of the corporation general of such information, including, without limitation, posting on the Company's investor relations website. In addition to satisfying the foregoing requirements under our bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must also comply with the additional requirements of Rule 14a-19 under the Exchange Act.

Our board of directors believes that management speaks for Zscaler, Inc. IndividualHowever, individual board members may, from time to time, communicate with various constituencies that are involved with the Company, but it is expected that board members would do this with knowledge of management and, in most instances, only at the request of management.

In cases where stockholders and other interested parties wish to communicate directly with our non-management directors, messages can be sent to our Secretary, at Zscaler, Inc., 120 Holger Way, San Jose, California 95134. Our Secretary monitors these communications and will provide a summary of all received messages to the board of directors, or an appropriate committee of the board of directors, at each regularly scheduled quarterly meeting of the board of directors. Our board of directors generally meets on a quarterly basis.board. Where the nature of a communication warrants, our Secretary may determine, in his or her judgment, to obtain the more immediate attention of the board of directors, independent directors, appropriate committeecommittees, or members of committees of the board, of directors or non-management director, of independent advisors to the Company or of Company management, as our Secretary considers appropriate.

Our Secretary may decide in the exercise of his or her judgment whether a response to any stockholder or interested party communication is necessary.

This procedure for stockholder and other interested party communications with the non-management directors is administeredoverseen by the Company’s nominating and corporate governance committee. This procedure does not apply to (a) communications to non-management directors from officers or directors of the Company who are stockholders, (b) stockholder proposals submitted pursuant to Rule 14a-8 under the Exchange Act or (c) communications to the audit committee pursuant to the Complaint Procedures for Accounting and Auditing Matters.

One of the key functions of our board of directors is informed oversight of our risk management process which risks include, among others, strategic, financial, business and operational, cybersecurity, legal and regulatory compliance, and reputational risks. Our board of directors does not have a standing risk management committee, but rather administers this oversight function directly through the board of directors as a whole, as well as through its standing committees that address risks inherent in their respective areas of oversight. In particular, our board of directors is responsible for monitoring and assessing strategic risk exposure. Our audit committee is responsible for reviewing and discussing our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies with respect to risk assessment and risk management, including oversight of the performance of our internal audit function. In addition to oversight of the performance of our external and internal audit functions, our audit committee also monitors compliance with legal and regulatory requirements and reviews related party transactions. Our audit committee responsibilities also include oversight of cybersecurity risk management, and, to that end, members of the audit committee meet frequently with management and companyCompany leadership responsible for cybersecurity risk management and receives periodic reports from management, as well as incremental reports as matters arise. Our nominating and corporate governance committee monitors the effectiveness of our corporate governance guidelines and oversees our ESG programs. Our compensation committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

Each non-employee director is eligible to receive compensation for his or her service consisting of annual cash retainers and equity awards under our outside director compensation policy. Our outside director compensation policy was crafted in consultation with Compensia, Inc. ("Compensia"), an independent compensation consulting firm engaged by our compensation committee. Compensia provided us with competitive data, analysis and recommendations regarding non-employee director compensation, which includes a mix of cash and equity-based compensation. After careful consideration of this information and the scope of the duties and responsibilities of our non-employee directors, our board of directors approved our outside director compensation policy. We believe this policy provides reasonable compensation to our non-employee directors that is commensurate with their contributions and appropriately aligned with our peers. We also reimburse our directors for expenses associated with attending meetings of our board of directors and board committees.

For fiscal 2022,2023, there were no changes in the director compensation policy, and non-employee directors were entitled to receive the following cash compensation for service in the following positions:

In addition, non-employee directors were eligible to receive the following equity awards for board service:

The number of RSU awards for each of the initial and annual RSU grant will be determined by dividing the annual equity value by the average closing price of Zscaler common stock on the Nasdaq Global Select Market for the 30 trading days ending on the date that is five days prior to the grant date, rounded up to the nearest share.

All cash payments to non-employee directors who served in the relevant capacity at any point during the immediately preceding prior fiscal quarter will be paid quarterly in arrears on a prorated basis. A non-employee director who served in the relevant capacity during only a portion of the prior fiscal quarter will receive a pro-rated payment of the quarterly payment of the applicable cash retainer.

Dr. Sinha, who resigned as an officer of the Company effective October 21, 2022, was eligible to receive compensation as a non-employee director commencing with the fiscal quarter beginning November 1, 2022.

We believe that our directors should hold a significant amount of Company equity to link their long-term economic interests directly to those of our stockholders. Accordingly, effective January 1, 2022, we have established requirements that our directors own at minimum equity of the Company valued at four times their annual retainer for service on our board of directors (not including committee service). We believe that this multiple constitutes significant amounts for our directors and provides a substantial link between the interests of our directors and those of our stockholders. Compliance with these guidelines for non-employee directors is required within five years of becoming subject to them. For purposes of meeting the ownership requirements, unvested RSU

awards are counted, but unearned performance awards and unexercised stock options are not. At the end of fiscal 2022,2023, each of our non-employee directors exceeded or was on track to meet these guidelines based on their current rate of stock accumulations in the time frames set out in the guidelines.

The following table sets forth information regarding compensation earned by or paid to our non-employee directors during the fiscal year ended July 31, 2022:2023:

The following table lists all outstanding equity awards held by our non-employee directors as of July 31, 2022.2023.

We believe a thoughtful, robust and deliberate ESG program will drive sustained value creation for our stakeholders. FocusedWe focus on transparency, our ESG program was launched in 2021 as a natural extension of our well-established company culture. This program includes a range of initiatives centered around sustainability, corporate responsibility, diversity, protection of customers and their data, and building trust through good corporate governance. From ourZscaler's inception, we have relied upon our strong cultural values to guide ethical business practices, in effortsand to always do what is right for our customers and our business. We established a Code of Conduct, reflecting strong ethical principles, to communicate our expectations to employees. We striveIn addition, in fiscal 2023, we implemented a supplier code of conduct to always comply with applicable lawscommunicate our ethical expectation to our vendors and regulations, and to fully address all compliance requirements. And, because there is always room for growth, wesuppliers. We continuously assess our operations to seek opportunities for improvement, all while evaluating and addressing risks as they arise.

As part of this ongoing process, our board maintains oversight over ESG matters through our nominating and corporate governance committee, while our executive management team manages and monitors such matters on a day-to-day basis throughout the year. Our nominating and corporate governance committee reviews our ESG program at least annually to ensure that the strategies, initiatives, and policies are effectively addressing our ESG priorities and driving long-term value for our stakeholders. In addition, our audit committee oversees privacy and cybersecurity risks.

Each director’s term continues until the election and qualification of such director’s successor, or such director’s earlier death, resignation, or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of our directors. This classification of our board of directors may have the effect of delaying or preventing changes in control of the Company.

If you are a stockholder of record and you sign your proxy card or vote over the internet or by telephone but do not give instructions with respect to the voting of directors, your shares will be voted FOR the election of Mr. Brown, Mr. Darling and Mr. Schneider.Chaudhry. We expect that Mr. Brown, Mr. Darling and Mr. SchneiderChaudhry will accept such nomination; however, in the event that athe director nominee is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee who shall be designated by our board of directors to fill such vacancy. If you are a beneficial owner of shares of our common stock and you do not give voting instructions to your broker, bank or other nominee, then your broker, bank or other nominee will leave your shares unvoted on this matter.

Our audit committee has appointed PwC, as our independent registered public accounting firm to audit our consolidated financial statements for our fiscal year ending July 31, 2023.2024. PwC has served as our independent registered public accounting firm since May 2015.

At the Annual Meeting, stockholders are being asked to ratify the appointment of PwC as our independent registered public accounting firm for our fiscal year ending July 31, 2023.2024. Stockholder ratification of the appointment of PwC is not required by our bylaws or other applicable legal requirements. However, our board of directors is submitting the appointment of PwC to our stockholders for ratification as a matter of good corporate governance. In the event that this appointment is not ratified by the affirmative vote of a majority of the voting power of the shares of our common stock present in person or represented by proxy at the Annual Meeting and entitled to vote, such appointment will be reconsidered by our audit committee. Even if the appointment is ratified, our audit committee, in its sole discretion, may appoint another independent registered public accounting firm at any time during our fiscal year ending July 31, 20232024 if our audit committee believes that such a change would be in the best interests of Zscaler and its stockholders. If the appointment is not ratified by our stockholders, the audit committee may reconsider whether it should appoint another independent registered public accounting firm. A representative of PwC is expected to be present at the Annual Meeting, will have an opportunity to make a statement if he or she wishes to do so, and is expected to be available to respond to appropriate questions from stockholders.

In the fiscal year ended July 31, 2022,2023, there were no other professional services provided by PwC that would have required our audit committee to consider their compatibility with maintaining the independence of PwC.

Our audit committee has established a policy governing our use of the services of our independent registered public accounting firm. Under the policy, our audit committee is required to pre-approve all audit and permissible non-audit services performed by our independent registered public accounting firm in order to ensure that the provision of such services does not impair such accounting firm’s independence. All fees paid to PwC for our fiscal years ended July 31, 20222023 and 20212022 were pre-approved by our audit committee.

The audit committee serves as the representative of our board of directors with respect to its oversight of:

The audit committee also reviews the performance of our independent registered public accounting firm, PwC, in the annual audit of our financial statements and in assignments unrelated to the audit, and reviews the independent registered public accounting firm’s fees.

The audit committee is currently composed of three non-employee directors. Our board of directors has determined that each current member of the audit committee is independent, and that Ms. Blasing qualifies as an “audit committee financial expert” under the SEC rules.

The audit committee provides our board of directors such information and materials as it may deem necessary to make our board of directors aware of financial matters requiring the attention of our board of directors. The audit committee reviews our financial disclosures and meets privately, outside the presence of our management, with our independent registered public accounting firm. In fulfilling its oversight responsibilities, the audit committee reviewed and discussed the audited financial statements in our fiscal year ended July 31, 20222023 Annual Report with management, including a discussion of the quality and substance of the accounting principles, the reasonableness of significant judgments made in connection with the audited financial statements, and the clarity of disclosures in the financial statements. The audit committee reports on these meetings to our board of directors.

The audit committee has reviewed and discussed with Zscaler’s management and PwC the audited consolidated financial statements of Zscaler contained in Zscaler’s Annual Report on Form 10-K for fiscal year 2022.2023. The audit committee has also discussed with PwC the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC.

The audit committee has received and reviewed the written disclosures and the letter from PwC required by applicable requirements of the PCAOB regarding PwC’s communications with the audit committee concerning independence, and has discussed with PwC its independence from Zscaler.

Based on the review and discussions referred to above, the audit committee recommended to the board of directors that the audited consolidated financial statements be included in Zscaler’s Annual Report on Form 10-K for its fiscal year 20222023 for filing with the SEC. The audit committee also has selected PwC as the independent registered public accounting firm for fiscal year 2023.2024. Our board of directors recommends that stockholders ratify this selection at the Annual Meeting.

Respectfully submitted by the members of the audit committee of the board of directors:

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and Section 14A of the Exchange Act enables stockholders to approve, on an advisory or non-binding basis, the compensation of our Named Executive Officers as disclosed in this Proxy Statement in accordance with the rules of the SEC. This proposal, commonly known as a “Say-on-Pay” proposal, 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 or any specific Named Executive Officer, but rather the overall compensation of all of our Named Executive Officers and the philosophy, policies and practices described in this Proxy Statement.

The Say-on-Pay vote is advisory, and therefore is not binding on us, our compensation committee or our board of directors. The Say-on-Pay vote will, however, provide information to us regarding investor sentiment about our executive compensation philosophy, policies and practices, which our compensation committee will be able to consider when determining executive compensation for the remainder of the current fiscal year and beyond. Our board of directors and our compensation committee value the opinions of our stockholders. To the extent there is any significant vote against the compensation of our Named Executive Officer as disclosed in this Proxy Statement, we will endeavor to communicate with stockholders to better understand the concerns that influenced the vote and consider our stockholders’ concerns. Our compensation committee will evaluate whether any actions are necessary to address those concerns.

“RESOLVED, that the stockholders approve, on an advisory basis, the compensation paid to the Named Executive Officers, as disclosed in the Proxy Statement for the Annual Meeting pursuant to the compensation disclosure rules of the SEC, including the compensation discussion and analysis, compensation tables and narrative discussion, and other related disclosure.”

The following table sets forth certain information about our executive officers and their respective ages as of November 1, 2022.2023. Officers are electeddesignated by the board of directors to hold office until their successors are elected and qualified.

This Compensation Discussion and Analysis provides information regarding the fiscal 20222023 compensation program for our principal executive officer, our principal financial officer, and our three other executive officers at fiscal year-end who were our most highly-compensated executive officers (our “Named Executive Officers”). This section provides details about our executive compensation philosophy, objectives and design; how and why our compensation committee arrived at the specific compensation policies and decisions relating to fiscal 2023, which resulted in the compensation as set forth in the Summary Compensation Table and other compensation tables contained in this proxy statement.

As has historically been the case when designing our compensation programs, in fiscal 2023, our compensation committee aimed to tie our Named Executive Officers’ compensation to key performance measures focusing on growth and capturing additional market share. Specifically, in addition to a base salary, our Named Executive Officers’ target total direct compensation included annual short-term and long-term incentives that are based on our attainment of key business objectives focused on growth. For fiscal 2022,2023, achievement of cash bonuses was determined based on revenue and calculated billings performance metrics, as well as corporate and individual executive performance metrics and goals, and attainment of our newly issued performance-based equity awards will be determined based on long term, multi-year ARR growth targets.

For fiscal 2023, our Named Executive Officers were:

On October 6, 2022,During fiscal 2023, Dr. Sinha informed us of his intention to resign as our President effective as of October 21, 2022. Dr. Sinha continuesis expected to continue to serve as a member of the Board.Board through the commencement of the Annual Meeting. Dr. Sinha did not receive any severance payments or benefits and forfeited all unvested equity awards in connection with his resignation. During fiscal 2023, Syam Nair joined us as our new CTO assuming many of Dr. Sinha's previous responsibilities. In July 2023, our board of directors designated Syam Nair as an officer under Rule 16a-1(f) of the Exchange Act and as an executive officer under Rule 3b-7 of the Exchange Act. Mr. Nair's compensation is described throughout this section, including compensation decisions made prior to his designation as an executive officer.

This Compensation Discussion and Analysis describes the material elements ofWe design our executive compensation program during fiscal 2022. It also provides an overviewto achieve the following objectives, consistent with our “pay for performance” philosophy:

We believe that our executive compensation philosophy, including our principalprograms should include short-term and long-term elements which reward consistent performance that meets or exceeds expectations. We evaluate both performance and compensation policies and practices. Finally, it analyzes how and why the compensation committee of our board of directors (the “compensation committee”) arrived at the specific compensation decisions for our Named Executive Officers in fiscal 2022 and discusses the key factorsto ensure that the compensation committee considered in determining their compensation.

We believe that organizations are still in the early stages of embracing cloud-based business solutions and adopting the security and networking solutions, including our products, that are necessary to secure and manage cloud-based operations. To be successful in this emerging market, we believe that delivering growth and capturing market share are paramount.paramount, while prudently managing expenses as we invest in our business. We want all our employees and executives, particularly our CEO and COO, who have the most influence over sales activities, to be highly focused on maximizing growth. To that end, we focus our compensation programs on aggressive growth targets that we believe will deliver long-term stockholder value in a highly competitive and emerging market. We have historically focusedIn addition, beginning in fiscal 2024, the compensation committee introduced and expects to continue to incorporate performance metrics for all offocused on operating profitability into our incentive compensation programs on driving aggressive growth in each fiscal year. Since we strongly believe that establishing and meeting aggressive growth targets in both the short term and the long term is the best way to deliver sustainedprograms.

Our focus on growth in compensating and incentivizing our employees, including our executives, has succeeded in delivering both robust financial performance and also long-term value to our stockholders.

Fiscal 20222023 was a strong year for us marked by significant achievement and growth across all of our key metrics. Fiscal 20222023 highlights were as follows:

Pay-for-Performance

We believe our executive compensation program is reasonable, competitive, and appropriately balances the goals of attracting, motivating, rewarding, and, most importantly, retaining our Named Executive Officers with the goal of aligning their interests with those of our stockholders. To ensure this alignment and to motivate and reward individual initiative and effort, a substantial portion of our Named Executive Officers’ target annual compensation opportunity is both variable in nature and “at-risk.”

We emphasize variable compensation that appropriately rewards our Named Executive Officers through two separate compensation elements:

These variable pay elements ensure that, each year, a substantial portion of our Named Executive Officers’ target total direct compensation is contingent (rather than fixed) in nature, with the amounts ultimately payable subject to variability above or below target levels commensurate with our actual performance.

We endeavor to maintain sound governance standards consistent with our executive compensation policies and practices. The compensation committee evaluates our executive compensation program on a regular basis to ensure that it is consistent with our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent.
