How CAIN-42 compares · Platform agent governance
CAIN-42 vs Microsoft Agent 365 + Entra Agent ID
Agent 365 (GA 2026-05-01) is a centralized agent registry, lifecycle and access-control plane in the M365 admin center, with Entra Agent ID treating agents as first-class identities: agent blueprints, on-behalf-of delegation, and Conditional Access for agents.
What Microsoft Agent 365 + Entra Agent ID does well
- Centralized enterprise agent registry, lifecycle and offboarding.
- Agents as first-class identities with on-behalf-of delegation and Conditional Access.
- Large enterprise distribution, SSO and vendor compliance programs.
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.
