Best on-premise AI governance tools
28 tools · last reviewed 2026-07
Some organisations cannot send prompts, model outputs or evidence to a vendor's cloud — whether for regulatory, sovereignty or classification reasons. The vendors below offer on-premise or self-hosted deployment, letting governance and inspection happen inside your own network boundary.
