• Experience of vulnerability management tooling and process (e.g. Qualys, Wiz, Gitlab or equivalent), and of scoping and interpreting external penetration tests for a business audience.
• Proven track record leading cyber security incident response, including coordinating across internal teams, suppliers and senior/Board-level stakeholders.
• Experience assessing and assuring third-party/supplier cyber security, including supplier on-boarding, contract security requirements and ongoing supply chain risk management.
