CAIN-42 vs Zenity
A security platform for AI agents: discovery of agents, risk analysis, and runtime policy and guardrails for low-code and developer agents.
What Zenity does well
- Agent discovery and risk posture across the enterprise.
- Guardrails for no-code and pro-code agents.
- Focused on the agent-security problem.
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.
