CAIN-42 vs WitnessAI
An AI security and governance platform for visibility and control across LLM usage and agents, with policy enforcement and safety controls.
What WitnessAI does well
- Cross-model visibility and policy enforcement.
- Controls aligned to enterprise policy teams.
- Independent of a single model vendor.
What CAIN-42 does differently
- Enforces at the tool-call boundary, before anything runs.
- Orders authorization through a Byzantine quorum (3-of-4): one "yes" is never enough.
- Leaves a per-action signed receipt you can verify offline with a clean-room verifier.
- Authority continuity: a change to the model, tool, memory, skill or delegation forces a re-check.
- Self-serve from $19.75/mo; runs hosted, self-hosted or air-gapped.
