Risk Management and Strategy

The nature of Reddit’s business makes the company susceptible to cybersecurity attacks. To address this, we maintain a cybersecurity risk management program with policies and controls designed to protect our platform and data from cyber threats. Our cybersecurity risk management program is intended to protect the confidentiality, integrity, and availability of our critical systems and information. Our cybersecurity risk management program includes a cybersecurity incident response plan. We design and assess our cybersecurity risk management program based on applicable laws and regulations and remain informed by industry standards and industry-recognized practices.

Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels, and governance processes that apply across the enterprise risk management program.

Our cybersecurity risk management program includes:

•risk assessments designed to help identify material cybersecurity risks to our critical systems, information, products, services, and our broader enterprise IT environment;

•a dedicated security team principally responsible for managing (1) our cybersecurity risk assessment processes, (2) our security controls, and (3) our response to cybersecurity incidents;

•the use of external service providers, such as third-party penetration testing firms, bug bounty programs, or auditors, to assess, test, or otherwise assist with aspects of our security controls;

•cybersecurity awareness training of our employees, incident response personnel, and senior management, including onboarding sessions and annual refresher training to address evolving threats;

•a cybersecurity incident response plan that follows recognized frameworks (e.g., National Institute of Standards and Technology Cybersecurity Framework), outlines procedures for investigating and resolving incidents, and is supported by automated tools for threat triage and resolution; and

•a third-party risk management process for service providers, suppliers, and vendors incorporating evaluations like SOC 2 reports, annual reviews, and security questionnaires to ensure risks are understood and addressed.

We have not identified risks from known cybersecurity incidents, including as a result of any prior cybersecurity incidents, that have materially affected us, including our business, results of operations, and financial condition. We face risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our business, operations, results of operations, or financial condition. For additional information about these risks, see Part I, Item 1A, “Risk Factors” in this Annual Report on Form 10-K.

Cybersecurity Governance

Our Board of Directors considers cybersecurity risk as part of its risk oversight function and has delegated to the Audit Committee (the “Committee”) oversight of cybersecurity and other information technology risks. The Committee oversees management’s implementation of our cybersecurity risk management program.

The Committee receives regular reports from management on our cybersecurity risks. In addition, management updates the Committee, as necessary, regarding any material cybersecurity incidents, as well as any incidents with lesser impact potential.

The Committee reports to the full Board of Directors regarding its activities, including those related to cybersecurity. The full Board of Directors also receives briefings from management on our cyber risk management program. Board members receive presentations on cybersecurity topics from our Chief Information Security Officer (“CISO”), internal security staff, or external experts as part of the Board of Directors’ continuing education on topics that impact public companies.

Our CISO, Fredrick Lee, has over twenty years of experience in information security, engineering, and other technology-related roles. Mr. Lee currently oversees Reddit’s Security, Privacy, Assurance, Corporate Engineering (“SPACE”) team, which is responsible for assessing and managing our material risks from cybersecurity threats. Our SPACE team has primary responsibility for our overall cybersecurity risk management program and supervises both our internal cybersecurity personnel and our retained external cybersecurity consultants. Our SPACE team has a strong foundation of expertise, developed over years of experience in cybersecurity and engineering across diverse industries, including technology.

Our SPACE team supervises efforts to prevent, detect, mitigate, remediate, and appropriately report cybersecurity risks and incidents through various means, which may include briefings from internal security personnel; threat intelligence and other information obtained from governmental, public, or private sources, including external consultants engaged by us; and alerts and reports produced by security tools deployed in the IT environment.
