AI vendors with ISO 42001 certification
AI vendors certified to ISO/IEC 42001, the international standard for AI management systems published December 2023.
ISO/IEC 42001 is the first international standard for an AI Management System (AIMS), published December 2023. It is the AI-specific cousin of ISO 27001, certifiable through accredited bodies, with 38 controls in Annex A and the same management-system clauses (4-10) as the rest of the ISO 27000 family. Adoption is early but accelerating among mature AI vendors. Holding ISO 42001 is a strong signal that the vendor systematically governs AI lifecycle risk rather than treating AI safety as ad hoc.

Buyer checklist
- Confirm whether the vendor holds an active certification or is "aligned with" the standard (the latter is self-declared).
- Verify the certificate scope statement covers the specific AI system you intend to use.
- Check whether ISO 27001 is also certified — 42001 layers on top of, not replaces, an information security baseline.
- Ask how the AIMS handles model lifecycle changes: training-data updates, fine-tuning, capability expansions.
- For high-risk EU AI Act use cases, ask how 42001 controls map to the Act's technical documentation requirements.
Compliance is necessary, not sufficient. Holding ISO 42001 is a meaningful baseline, but no certification covers AI-specific risk end-to-end. Layer this on top of vendor-specific diligence — sub-processor disclosure, training-data policy, model card transparency, dependency-chain mapping.
