What happened
ENISA published a recommendations document for national competent authorities, EU policymakers, defenders and service providers to build 'the necessary operational capabilities to face machine-speed threats' posed by frontier AI. The paper argues that vulnerability exploitation windows are compressing to the point where 'the exploitation window can begin before patch deployment' and that ENISA's existing vulnerability-management guidance must adapt to attacker use of AI at machine speed. ENISA frames these as an initial, non-exhaustive set of recommendations that it will refine in cooperation with Member States and align to the Commission's Action Plan on Cybersecurity and AI.
Why it matters
For CISOs and security leaders, this is the first EU regulatory articulation that the vulnerability-to-exploitation timeline has compressed below traditional patch-management cycles because of AI-enabled attackers, directly informing how national authorities will expect incident response and disclosure practices to evolve.
Action needed
Map current vulnerability management and incident response SLAs against ENISA's machine-speed threat assumptions; flag gaps to the board risk committee ahead of anticipated binding EU guidance.
