ISO 42001 and ISO 27001 are often confused — both are ISO management-system standards, but they govern different things. This guide explains the difference, where they overlap, and whether you need both, plus how ISO 42001 compares to the NIST AI RMF. Part of our guide to ISO 42001 certification.
ISO/IEC 27001 is the standard for an Information Security Management System (ISMS) — protecting the confidentiality, integrity and availability of information. ISO/IEC 42001 is the standard for an AI Management System (AIMS) — governing the responsible development and use of AI, including risks security standards don't address, like bias, explainability, transparency and societal impact.
Both are management-system standards with the same backbone — leadership, risk, controls, audit, improvement — and both care about data. If you hold ISO 27001, you already run the machinery ISO 42001 needs; you extend it to AI rather than build a second system from scratch, which is why 27001-certified organisations reach 42001 faster.
If you handle sensitive information, ISO 27001 remains essential; if you build or deploy AI, ISO 42001 adds the AI-specific governance 27001 doesn't cover. Many organisations pursue both and run them as one integrated management system.
The NIST AI Risk Management Framework is a voluntary US framework (Govern, Map, Measure, Manage), not a certifiable standard. ISO 42001 is certifiable; the NIST AI RMF is a flexible reference. Many organisations use the NIST AI RMF operationally and certify to ISO 42001 for the credential — the two map together well. See our overview of the AI governance framework.
AramGRC helps you extend an existing ISO 27001 system to ISO 42001, or build the AI management system from scratch, and map it to the NIST AI RMF and the EU AI Act at the same time.
ISO 27001 manages information security; ISO 42001 manages responsible AI, including bias, transparency and oversight. They share the same management-system structure and complement each other.
If you handle sensitive data, ISO 27001 stays essential; if you build or deploy AI, ISO 42001 adds AI-specific governance. Many organisations hold both as one integrated system.
Yes — an existing ISO 27001 management system provides most of the structure ISO 42001 needs, which shortens the path to certification.
No — ISO 42001 is a certifiable standard; the NIST AI RMF is a voluntary framework. They map together well, and many organisations use both.
