Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	At Dun & Bradstreet, we are committed to identifying, categorizing, evaluating, managing, and mitigating risks related to our data, technology, and operations through our enterprise risk management (“ERM”) program, our cybersecurity (“Cyber”) program, and our compliance and ethics (“C&E”) program. Our ERM, Cyber, and C&E programs continuously coordinate on vulnerability, threat, and risk monitoring and periodic reporting to provide a comprehensive view of evolving cybersecurity risks. Through these programs, we evaluate risks at various levels ranging from systems, applications, processes, products, and analytics, to incidents, and macro and aggregate risks in the environment and ecosystems in which we operate. We also utilize this risk-based approach to assess, identify and manage risks from cybersecurity threats associated with third parties with whom we do business, including those that provide services, systems, and data processing. We apply consistent methodologies to evaluate inherent and residual risk levels to identify and prioritize management of our highest risks, including material cybersecurity risks. We utilize our risk management processes to prioritize our annual Cyber workplans, including monitoring and internal audit and external assurance reviews, such as our SOC 2, Type 2 Independent Service Auditor's Report on controls relevant to security, availability, and confidentiality, and our participation in the TRUSTe Data Privacy Framework verification program. We have engaged an industry-leading cybersecurity firm to conduct a cyber threat profile that addresses not only our immediate environment, but also the broader cyber threat landscape and threat actors that may be targeting our industry or the geographic locations in which we operate. We actively participate in several global and regional trade and policy associations, think tanks, and professional organizations related to cybersecurity, information policy, privacy, and artificial intelligence to maintain timely insights on rapidly evolving cybersecurity and data risks affecting our business. We take a holistic approach to identification, mitigation and management of cybersecurity and data risks through governance and compliance processes integrated across our Cyber program and our C&E program. These processes include integrated policies, risk assessments, impact assessments, third party reviews and monitoring, incident response, and external certification programs such as ISO 27001: Information Security Management Systems, ISO 27701: Privacy Information Management Systems, APEC Cross-Border Privacy Rules System and TRUSTe Responsible AI. We recognize that our first line of defense is our employees and we incorporate cybersecurity awareness education in our annual Code of Conduct and Ethics training program to ensure our employees understand their roles in safeguarding against potential cyber threats.
