Operational guidance, not legal advice. This page distills named public sources (regulator guidance and industry practice).

How does ISO 42001 compare to ISO 27001?
Last verifiedISO 42001 governs an AI management system; ISO 27001 governs information security. Both use Annex SL clauses 4–10 and are certifiable — but scopes and Annex A themes differ. Not legal advice.
Comparison, last verified 10 September 2026 against ISO/IEC 42001:2023 and ISO/IEC 27001:2022. Criteria: scope, controls, certification path, structure. SRM recommends integration where both apply — not a legal rule.
Comparison criteria
This table compares published standard text on: subject matter, Annex A control families, distinctive requirements, certification mechanism, and harmonised-structure overlap. It does not rank which YOU need — counsel and contracts decide.
Side-by-side table
| Dimension | ISO/IEC 42001:2023 | ISO/IEC 27001:2022 | Kind of text |
|---|---|---|---|
| Scope | AI management system (AIMS) | Information security management system (ISMS) | International standard |
| Primary concern | Responsible AI development and use; societal impact | Confidentiality, integrity, availability of information | International standard |
| Annex A themes | Nine AI control areas (policies, lifecycle, data, transparency, third parties) | Information-security controls (organizational, people, physical, technological) | International standard |
| Distinctive requirement | AI system impact assessment | Information-security risk treatment | International standard |
| Certification | Accredited CB under ISO/IEC 17021-1; 3-year cycle | Same certification machinery | Professional standard — ISO/IEC 17021-1 |
| Annex SL overlap | Clauses 4–10 shared structure — integrable | Clauses 4–10 shared structure — integrable | Harmonized structure fact |
One does not substitute for the other
- ISO 27001 certification does not demonstrate ISO 42001 conformity.
- ISO 42001 certification does not demonstrate ISO 27001 conformity.
- Many organisations run an integrated management system — SRM recommendation when both AI and security matter, not a standard mandate.
- Evidence for shared clauses (internal audit, management review) can be reused with clear scope labels.
What to do now
- If ISO 27001 certified, gap Annex A AI themes against YOUR AI inventory.
- Reuse SoA process and audit calendar — extend, do not duplicate blindly.
- Read controls-explained for the nine AI themes ISO 27001 does not cover.
Checklist
- ☐ Both standards' applicability assessed separately?
- ☐ Integrated SoA or linked SoAs documented?
- ☐ Evidence tagged by framework to avoid auditor confusion?
Where this shows up in ShipReady Metrics
The 24-framework crosswalk maps SOC 2, ISO 27001, and ISO 42001 to shared canonical controls with crosswalk-density honesty. Evidence collected once can feed multiple framework views — coverage is not certification.
