How CAIN-42 compares · AI security & scanners
CAIN-42 vs Protect AI / Palo Alto Prisma AIRS
AI security suites that scan models, ML supply chains and prompts, and detect attacks on AI applications. Prisma AIRS brings this into the Palo Alto enterprise security platform.
What Protect AI / Palo Alto Prisma AIRS does well
- Model and ML supply-chain scanning and AI-SPM.
- Enterprise security distribution and threat research.
- Red-teaming and runtime protection for AI apps.
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.
