Third-party AI under ISO 42001

By Sam Rivera, Founder, SentinelPanda · June 20, 2026 · 1 min read · ISO 42001

ISO 42001 does not only govern the AI you build — it governs the AI you buy, which for most organisations is most of it.

You mostly buy AI

Most organisations consume AI through third-party APIs and AI-powered tools rather than building models. ISO 42001 reflects this: the AIMS governs the AI you acquire and integrate, not just what you develop. Bought-in AI is in scope, which matters because it is where most of the risk actually sits.

What to govern

For third-party AI, the standard expects diligence and ongoing management: what the provider does with your data, the provider's own responsible-AI governance, the system's behaviour and limitations, and who is accountable when outputs are wrong or harmful. These are the AI-specific extensions to ordinary vendor diligence.

Data is the sharp edge

As with any third-party AI, the risk that bites is data leaving your control into a model you do not govern — confirm contractual data terms before sensitive data flows. Regulated data needs the same care as anywhere else.

Extend vendor management

Govern third-party AI through your existing vendor-management program — inventory, tier, diligence, review — with AI questions added, all under the AIMS. SentinelPanda tracks third-party AI alongside your other vendors with the AI diligence captured.
