What is zero-trust AI governance?

Zero-trust AI governance applies zero-trust principles to the data flowing through an AI system. Every retrieval is authorised against the caller's identity at the moment of the request, and nothing is trusted simply because it is already inside the pipeline. In practice it means the vector store grants no more access than the source systems it was built from.

The three requirements are a live inventory of what data the system can reach, identity-aware enforcement at the retrieval boundary, and an audit trail of both what was returned and what was withheld.

The inventory is the part that decays. Connectors are added, sources change shape, and a governance posture established at launch quietly stops describing the system. A live data bill-of-materials — regenerated rather than documented — is what keeps it honest.

The approach we built for a US AI-security client has been recognised by a leading industry analyst in its guide to AI trust, risk, and security.
