CAIN-42 CAIN StudioPricing
Security is never a paid feature. Every plan gets the whole decision path; plans differ by scale, retention and operations.
Every new account starts with 30 days of full Enterprise limits, no card. When the 30 days end the account continues on Free. You are never charged automatically, and nothing is deleted by the change. Run cain trial or open your dashboard to see what you used and which plan it fits.
On every plan
- Identity, policy, authorization, risk, enforcement
- Signed evidence and independent verification
- MCPGate enforcement in the call path
- Tenant isolation and every security control
- Python SDK and CLI (install package: see the homepage quickstart)

Measured on our own code: FALSEWORK re-checks the CAIN-42 codebase every 42 seconds and KEYSTONE applies only fixes it has proved. See the results.

Trial, cancellation and refunds
The 30-day full evaluation needs no card. Paid plans are optional and can be cancelled any time from your dashboard; you keep access until the period ends. The first charge is refundable within 7 days: see the refund policy. Limits shown are the limits in force; nothing here is a contractual SLA.
