SIR|Signal Integrity Resolver

A deterministic gate in front of inference.

Rules-only enforcement with signed audit artefacts.

What SIR is

  • A pre-inference governance gate

    It sits upstream of the model, intercepting prompts before they are processed by the LLM.

  • Deterministic and explainable

    Rules-only logic. No "AI watching AI." You know exactly why a prompt was blocked.

  • Proof-producing

    Emits a signed certificate, run archive, and hash chain for every audited run.

What SIR isn't

  • Not post-hoc moderation

    It doesn't clean up the mess after it happens. It prevents the request from reaching the model.

  • Not a probabilistic classifier

    It does not guess. There is no confidence score. It is PASS or BLOCK.

  • Not a compliance certification

    SIR is a tool to enforce policy, not a legal guarantee of compliance.

Integration Modes

Flexible deployment options to match your governance workflow.

Audit-only
Passive Verification

Run test suites against your models and publish verifiable audit artefacts. Perfect for periodic compliance checks and regression testing without affecting production latency.

Gating
Active Enforcement

Enforce policies in real-time in front of agents or models. Blocks non-compliant requests instantly and generates an audit record for each enforced decision.
