CAIN-42 CAIN StudioHow CAIN-42 compares
CAIN-42 vs HiddenLayer
HiddenLayer is a leading AI security platform: runtime detection/response, agentic visibility, model scanning and red teaming, built on adversarial research. CAIN-42 shares the runtime positioning but enforces at the execution boundary with cryptographic ordering.
At a glance
What HiddenLayer does well
- Model scanning for backdoors, malware and vulnerable dependencies before deployment.
- Deep adversarial/threat research and an AI-threat report.
- Agentic investigation and threat hunting.
- Established enterprise deployments.
What CAIN-42 does differently
- Enforces at the tool-call boundary, before anything runs.
- Orders authorization through a Byzantine quorum (3-of-4), so a single yes is never enough.
- Leaves a per-action signed receipt you can verify offline with a clean-room verifier.
- Self-serve from $19.75/mo; the free tier includes the whole decision path.
- Runs hosted, self-hosted, or air-gapped on your own KMS root of trust.
Capability difference
| Capability | CAIN-42 | HiddenLayer |
|---|---|---|
| Blocks the tool call at the boundary | Yes | Yes (runtime detection & enforcement) |
| Byzantine-ordered authorization (quorum cert) | Yes | No |
| Per-action signed receipt, offline-verifiable | Yes | No |
| Model scanning / malicious weights | No (out of scope) | Yes (core strength) |
| Agentic visibility & threat hunting | Yes (decision + evidence trail) | Yes |
| Self-serve start | Yes | Talk to sales |
When to pick which
Pick HiddenLayer for model supply-chain scanning and adversarial research. Pick CAIN-42 when the risk is execution: you want authorization ordered by a quorum and a per-action receipt, self-serve and cheap.
