How CAIN-42 compares · Agent identity & access

CAIN-42 vs Aembit

A workload identity and access management platform for non-human identities, including securing agent access to MCP servers and APIs.

What Aembit does well

  • Purpose-built for non-human workload access.
  • Credential brokering and policy for services.
  • Focus on the access path, not the model.

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.
