Cybersecurity Risk Management, Strategy, and Governance [Line Items] |
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | Cybersecurity risk management is an integral part of Cadeler’s Health, Safety, Environmental and Quality (HSEQ) Management Principles & System. Cadeler’s overall cybersecurity program is based on the CIS Critical Security Controls (CIS18), supplemented by risk management procedures inspired by the ISO27001 security framework. These procedures include steps to assess the severity of cybersecurity threats across the Company, including onboard the Company’s fleet of vessels, which are then consolidated into the Company’s overall business risk register. The Company's executive management team is involved in these procedures and are updated yearly or in the case of major changes. The controls implemented through the CIS18 framework ensure timely handling of relevant cybersecurity threats and incidents, including threats and incidents associated with the use of critical systems and applications provided by third-party service providers, for which relevant attestations are received. Cadeler’s IT team also engages third-party security experts and strategic advisors for risk assessment, manual and technical security assessments of Cadeler's IT infrastructure, system enhancements and penetration testing. In addition, Cadeler’s IT team provides awareness training for employees and critical third parties and conducts simulated phishing attempts against all employees at least annually.
