Invarix.Guard.Evidence
Sealed audit records for AI decisions
Tamper evident records for the AI decisions you instrument. You seal batches under your own Ed25519 key, and an auditor can prove that nothing changed after sealing.
- One JSON file plus your public key: RFC 6962 inclusion proofs, verified offline
- Batches sealed with your key, which stays on your hardware
- No prompt fields in the record, by construction
- CloudEvents 1.0 on the wire, a documented format you can reimplement
Invarix.Gate
Action firewall for AI agents
Reads every tool call routed through it and flags the ones that cannot be undone. Deterministic rules and counters, no second model in the decision path, and a report of what enforce mode would have stopped.
- Destructive SQL, shell and git commands, cloud teardown, credential egress
- Call and token ceilings evaluated before the call, not read off an invoice
- Observe mode is the default and blocks nothing, including runaway loops
- A run report that names what it could not see
