EU AI Act for CISOs wiring it into an existing ISMS
You already run an ISO 27001/42001 management system. The AI Act is mostly new controls on top of it, not a parallel programme.
Wiring AI Act controls into an existing ISO 27001/42001 ISMS
Treat the AI Act as a control extension, not a new framework. The Article 9 risk-management system for high-risk AI is a continuous, iterative process across the system lifecycle — that is the same shape as your ISO 27001 risk treatment loop, so run it through the management system you already have rather than a separate register. ISO 42001 gives you the operational backbone: its AIMS clauses and Annex A AI controls map cleanly onto Article 9 risk management and Article 17 quality management, so a 42001 deployment satisfies most of the AI Act's organisational expectations. Article 12 logging and record-keeping is the one genuinely new technical demand — high-risk systems must automatically record events over their lifetime — so scope that into your existing logging and evidence-retention controls early. Done this way, the incremental work is classification, technical documentation, and the Article 12 log path, not a second ISMS.
EU AI Act framework details →Tier-check a system before folding it into the ISMS
Before deciding what folds into your existing ISO 27001/42001 controls, get the system's tier: the free EU AI Act Risk-Tier Checker returns a deterministic Regulation 2024/1689 classification (including GPAI) per system, so the "control extension, not new framework" decision above starts from a settled risk tier.

Do I need a separate AI Act risk register?
No. The Article 9 risk-management system is iterative and lifecycle-long, which mirrors your ISO 27001 risk treatment process. Extend the existing register with AI-specific risks and acceptance criteria rather than standing up a parallel one.
Does ISO 42001 cover the AI Act?
Not literally, but it is the most efficient operational backbone. ISO 42001 AIMS clauses and Annex A controls satisfy most of the Act's governance, risk, and quality-management expectations. The Copilot maps the overlap so you only document each control once.
What is genuinely new for a CISO already running an ISMS?
Mostly three things: high-risk classification and conformity assessment, the Article 11 technical documentation set, and Article 12 automatic event logging over the system lifetime. The rest folds into controls you already operate.
