Enterprise GRC is essential. It owns the control library, the audit calendar, Quality, HSE, privacy programs, and the board pack. None of that tells you whether last night’s agent called a write tool it should not have, or whether the completions API you exposed fails a jailbreak pack.
AI assurance is the technical discipline: inventory what is running, test it, watch it, score it with deductions you can read, and hash the evidence. When vendors collapse those jobs into “AI GRC,” teams buy a workflow and skip the lab.
OptimaTrust is built as continuous AI assurance and security. Use-case gates and policy packs exist because you cannot assure a system with no intended use. They are not a substitute for OptimaGRC. If you need both, connect them: assurance evidence informs GRC risk; GRC does not become a model fuzzer.
A practical test: if the product cannot mark a scanner unavailable without painting a green pass, it is not an assurance system. It is a dashboard.
