Investor Presentation September 2022 EXTERNAL CYBERSECURITY    

Safe Harbor Disclaimer and Forward-Looking Statements Statements in this presentation may constitute “forward-looking statements” under the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical fact, that address activities, events or developments that we expect, believe or anticipate will or may occur in the future, including statements related to plans, strategies and objectives of management, our business prospects, our systems and technology, product innovation, and our competitive position, are forward-looking statements. The words “will,” “may,” “believes,” “anticipates,” “thinks,” “expects,” “estimates,” “plans,” “intends,” and similar expressions are intended to identify forward-looking statements. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those anticipated by these forward-looking statements. The inclusion of any statement in this communication does not constitute an admission by ZeroFox or any other person that the events or circumstances described in such statement are material. In addition, new risks may emerge from time to time and it is not possible for management to predict such risks or to assess the impact of such risks on our business or financial results. Accordingly, future results may differ materially from historical results or from those discussed or implied by these forward-looking statements. Given these risks and uncertainties, the reader should not place undue reliance on these forward-looking statements. These risks and uncertainties include, but are not limited to, the following: our ability to recognize the anticipated benefits of the business combination; defects, errors, or vulnerabilities in ZeroFox’s platform, the failure of ZeroFox’s platform to help customers minimize cyber attacks on their assets, misuse of ZeroFox’s platform, or risks of product liability claims would harm ZeroFox’s reputation and adversely impact our business, operating results, and financial condition; if ZeroFox’s platform offerings do not interoperate with our customers’ network and security infrastructure, or with third-party products, websites or services, our results of operations may be harmed; we may not timely and cost-effectively scale and adapt our existing technology to meet our customers’ performance and other requirements; our ability to introduce new products and solutions and features is dependent on adequate research and development resources and our ability to successfully complete acquisitions; our success depends, in part, on the integrity and scalability of our systems and infrastructure; we rely on third-party cloud providers, such as Microsoft Azure, Amazon Web Services, and Cloudflare, to host and operate our platform, and any disruption of or interference with our use of these offerings may negatively affect our ability to maintain the performance and reliability of our platform which could cause our business to suffer; we rely on software and services from other parties; ZeroFox has a history of losses, and we may not be able to achieve or sustain profitability in the future; if organizations do not adopt cloud, and/or SaaS-delivered external cybersecurity solutions that may be based on new and untested security concepts, our ability to grow our business and our results of operations may be adversely affected; we have experienced rapid growth in recent periods, and if we do not manage our future growth, our business and results of operations will be adversely affected;

Safe Harbor Disclaimer and Forward Looking Statements we face intense competition and could lose market share to our competitors, which could adversely affect our business, financial condition, and results of operations; competitive pricing pressure may reduce revenue, gross profits, and adversely affect our financial results; adverse general and industry-specific economic and market conditions and reductions in customer spending, in either the private or public sector, including as a result of geopolitical uncertainty such as the ongoing conflict between Russia and Ukraine, may reduce demand for our platform or products and solutions, which could harm our business, financial condition and results of operations; the COVID-19 pandemic could adversely affect our business, operating results, and financial condition; if we fail to adapt to rapid technological change, evolving industry standards and changing customer needs, requirements or preferences, our ability to remain competitive could be impaired; if we are unable to maintain successful relationships with our channel partners, or if our channel partners fail to perform, our ability to market, sell and distribute our platform will be limited, and our business, financial position and results of operations will be harmed; we target enterprise customers and government organizations, and sales to these customers involve risks that may not be present or that are present to a lesser extent with sales to smaller entities; historically, one U.S. government customer has accounted for a substantial portion of IDX’s revenues and is expected to account for a substantial portion of our revenues following the business combination; we may need to raise additional capital to maintain and expand our operations and invest in new solutions, which capital may not be available on terms acceptable to us, or at all, and which could reduce our ability to compete and could harm our business; there may not be an active trading market for our common stock, which may make it difficult to sell shares of our common stock; our common stock price may be volatile due to factors outside of our control; the convertible notes issued in connection with the business combination may impact our financial results, result in the dilution of our stockholders, create downward pressure on the price of our common stock, and restrict our ability to raise additional capital or take advantage of future opportunities; we rely heavily on the services of our senior management team, and if we are not successful in attracting or retaining senior management personnel, we may not be able to successfully implement our business strategy; and our management has limited experience in operating a public company. Additional information concerning these, and other risks, is described under “Risk Factors” in the Amendment No. 1 to registration statement on Form S-1 filed on September 27, 2022. We expressly disclaim any obligation to update any of these forward-looking statements, except to the extent required by applicable law.    

Safe Harbor Disclaimer and Forward Looking Statements This presentation references non-GAAP financial measures, including non-GAAP gross profit, non-GAAP gross margin, non-GAAP subscription gross profit and non-GAAP subscription gross margin. Non-GAAP financial measures should be considered in addition to, and not as a substitute for, measures of financial performance prepared in accordance with GAAP. The use of these non-GAAP measures is limited as they include and/or do not include certain items not included and/or included in the most directly comparable GAAP measure. You should be aware that the Company’s presentation of these measures may not be comparable to similarly-titled measures used by other companies. Please refer to the Supplemental Financial Information section of this presentation for a reconciliation of the Non-GAAP financial measures included in this presentation to the most directly comparable GAAP measures. Market and Industry Data Information contained in this presentation concerning the market and the industry in which we compete, including general expectations of market opportunities and market sizes, are based on information from various third-party sources, publicly available information, various industry publications, internal data and estimates, and assumptions made by us based on such sources and our knowledge of the external cybersecurity market and data breach response market. Internal data and estimates are based upon information obtained from trade and business organizations and other contacts in the markets in which we operate and our management’s understanding of industry conditions. This information and any estimates provided herein involve numerous assumptions and limitations, and you are cautioned not to give undue weight to such information. Third-party sources generally state that the information contained in such sources have been obtained from sources believed to be reliable. Although we believe that such information is reliable, there can be no assurance as to the accuracy or completeness of such information. Industry and market data could be wrong because of the method by which sources obtained their data and because information cannot always be verified with complete certainty due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties. We have not independently verified any third-party information and each publication speaks as of its original publication date (and not as of the date of this presentation). In addition, we do not know all of the assumptions regarding general economic conditions or growth that were used in preparing the forecasts from the sources relied upon or cited herein. The industry in which we operate is subject to a high degree of uncertainty and risk. As a result, the estimates and market and industry information provided in this presentation are subject to change.

Financial Highlights

Revenue Growth Driven by Subscription 26% YoY Growth

Growth in Breach Response

ARR and Customer Growth Note: We define Annual Recurring Revenue (“ARR) as the annualized contractual value of all recurring revenue related to contracts in place at the end of the reporting date assuming any contract is renewed on its existing terms. We continue to include ARR from customers whose term has expired within 90 days of the applicable measurement date for which we are actively negotiating renewal. We define a customer as any entity that has entered into a distinct subscription agreement for access to the ZeroFox platform for which the term has not ended or with which we are continuing to provide service and negotiating a renewal contract that expired within 90 days of the applicable measurement date. We do not consider our channel partners as customers, and we treat managed service security providers, who may purchase our products on behalf of multiple companies, as a single customer.

Supplemental Financial Information

Non-GAAP Financial Measures In addition to our results determined in accordance with GAAP, we believe the following non-GAAP measures are useful in evaluating our operating performance. We use the following non-GAAP financial information to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance by excluding certain items that may not be indicative of our business, results of operations or outlook. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Other companies, including companies in our industry, may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. For example, free cash flow is not a substitute for cash used in operating activities. Additionally, the utility of free cash flow as a measure of our liquidity is limited as it does not represent the total increase or decrease in our cash balance for a given period. A reconciliation is provided below for each non-GAAP financial measure to the most directly comparable financial measure stated in accordance with GAAP. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures and not rely on any single financial measure to evaluate our business. Non-GAAP Gross Profit and Non-GAAP Gross Margin We define non-GAAP gross profit and non-GAAP gross margin as GAAP gross profit and GAAP gross margin, respectively, excluding stock-based compensation expense and amortization of acquired intangible assets. We believe non-GAAP gross profit and non-GAAP gross margin provide our management and investors consistency and comparability with our past financial performance and facilitate period-to-period comparisons of operations, as these measures eliminate the effects of certain variables unrelated to our overall operating performance. Non-GAAP Loss from Operations We define non-GAAP loss from operations as GAAP loss from operations, excluding stock-based compensation expense, amortization of acquired intangible assets, and public company offering costs. We believe non-GAAP loss from operations provide our management and investors consistency and comparability with our past financial performance and facilitates period-to-period comparisons of operations, as these measures eliminate the effects of certain variables unrelated to our overall operating performance.
