Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Commitment to Security Security is a foundation on which ZoomInfo builds and maintains customers’ trust. We are committed to protecting our information and our customers’ information from both intentional and unintentional misuse and have implemented a robust Information Security Management System (“ISMS”) that meets the ISO 27001 Standard requirements as well as the ISO 27701 (Privacy) and ISO 27017 (Cloud Security) standards. We have also earned AICPA’s SOC 2 attestation regarding the security, availability, and confidentiality controls around our services and meet the security requirements of the Cloud Security Alliance STAR program. Risk Management Framework Our security program is risk-driven and integrated into our overall enterprise risk management process. We emphasize risk detection, which serves as the foundation for risk management-related business decisions. Our ISMS provides the structure for our overall security program and serves to assess, manage, monitor, and minimize our cybersecurity risks. The program includes: •Context of the organization •Leadership •Planning •Support •Operation •Performance evaluation •Improvement The ISMS consists of a set of policies and procedures that serve as a foundation for risk identification and remediation across all company assets. ZoomInfo’s ISMS implementation allows for the appropriate integration of security controls into existing or newly created business processes. ZoomInfo’s risk management platform is loosely based on the ISO 31000 Risk Management Standard, and continuous risk assessment activities are conducted in partnership and coordination with risk owners in various functions. Cybersecurity Team and Internal Operations Our cybersecurity team is comprised of a diverse group of security veterans with experience managing all facets of information risk including, but not limited to, Application Security, Data Governance, Security Engineering, Security Processes and Services, Secure Software Development, Governance Risk and Compliance, Risk Management, Cyber Threat Intelligence, Breach Readiness, Cyber Defense Center for monitoring, Offensive Security, and Security Awareness. We also consult with outside experts to identify and implement best practices, help gauge the security climate, and identify effective methods for related skill development and information sharing. Our information security policies outline the roles and responsibilities within the organization, and our security team works directly with specific members of senior management we call “security ambassadors” to help ensure that the various information security directives are executed as required in their respective departments. Our security partners help to establish, assess, and enhance business processes by ensuring the required information security risk management practices are suitably embedded within their respective processes. All employees and contractors are required to participate in continuous and dynamic security awareness training. The training includes an overview of key security topics, policies, and responsibilities. Regular security bulletins are disseminated to employees and contractors with security alerts, tips and best practices, external resources, security procedures, and contact information so that they can ask security-related questions or raise concerns. Prevention, Detection, and Response ZoomInfo has implemented preventative security and detection measures, including asset protection and access controls in the following key areas: •Critical Assets •Data Protection •Application Protection •Cloud Security •Network Security •End Point Devices •Perimeter Defense •Physical Protection We also maintain written incident response plans and conduct periodic cross-functional tabletop exercises to help assess our incident response plans, processes, and capabilities in addressing cybersecurity threats. As part of our security framework and evaluation of our supply chain risks, we review our service providers’ security practices and require appropriate certifications from them. We also perform an analysis of controls to manage our third-party security risks.
