Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We depend on IT and OT for various operations, including refinery processes, petroleum movement monitoring in pipelines and terminals, and other critical processes and transactions. We utilize IT and OT systems across our operations to capture accounting, technical and regulatory data for archiving, analysis, and reporting. Our primary business systems mostly consist of purchased and licensed software programs that integrate with our internal solutions. Additionally, our technology encompasses a company-wide network through which employees have access to key business applications. We maintain and continually enhance a comprehensive, risk-based cybersecurity program aimed at safeguarding our data, along with the data of our customers and partners. The identification, assessment, and management of cyber risks fall under our Enterprise Risk Management (“ERM”) program, overseen by the Board of Directors. Our Chief Technology & Data Officer holds overall responsibility for IT, OT, and cybersecurity. Delek follows recognized cybersecurity frameworks with a Chief Information Security Officer dedicated to overseeing cybersecurity initiatives throughout the entire enterprise. Our risk assessment process related to cybersecurity includes identifying threats and conducting vulnerability assessments, likelihood and impact assessments related to our own information and OT systems as well as our third-party service providers. Delek collaborates with third-party vendors to leverage managed security services, enhancing Delek’s cybersecurity capabilities. Delek possesses monitoring capabilities for both its IT and OT infrastructure. To identify material cybersecurity risks, we use a combination of technical assessments, risk analysis, vulnerability scanning, incident and event monitoring, threat intelligence and third-party assessments along with ongoing monitoring and management. We manage our material cybersecurity risks through a combination of security measures, audits, training, planning, and testing. Delek has established processes for regular disaster recovery planning and response readiness testing. Our security approach also includes multiple layers of defense and testing of controls. We have implemented security measures, including segmentation, firewalls, intrusion detection systems, encryption, multi-factor authentication and data loss prevention designed to safeguard our systems and data. Furthermore, we have reinforced our data protection capabilities by investing in both hardware and software. Recognizing that humans are often the most vulnerable element of even the most secure computer architectures, Delek conducts mandatory security awareness programs, including required training and phishing campaigns for our employees. Delek also conducts monthly reviews of global cybersecurity incidents to ensure that appropriate mitigation measures are in place to guard against similar threats. Delek is committed to enhancing its organizational resilience through a multiyear, comprehensive incident response tabletop drill program. Building upon the success of the drill conducted in 2024 and previous years, we remain committed to continuous improvement and proactive preparedness in addressing potential challenges and effectively managing incidents. Delek has not experienced a significant cybersecurity breach or associated expenses, penalties, or settlements for the years ended December 31, 2024, 2023 and 2022. Delek continuously assesses and enhances the confidentiality, integrity, and availability of its IT and OT assets.
