Most AI governance guidance assumes you built the model. The reality in almost every enterprise is the opposite: AI arrives embedded in SaaS products, as API calls to foundation models, and as features enabled by default in tools already in use.
This whitepaper addresses that reality directly. It sets out where accountability sits between provider and deployer under the EU AI Act and ISO 42001, what a deployer can and cannot delegate, and the specific evidence a deployer must hold.
It includes a vendor question set covering training data, retention of prompts and outputs, evaluation evidence, sub-processors, model change notification and exit — the questions traditional security assessments do not ask.
