For AI Agent Operators

Your agents act.
Signet proves they were compliant.

Immutable audit trails for every decision, API call, and transaction your AI agents make. Mapped to the frameworks your auditors actually ask for.

What Signet Captures

Decision Lineage

Every reasoning step, from initial prompt to final action. Know why your agent did what it did, months after the fact.

agent.reason → agent.decide → agent.act

Tool Call Registry

Every API called, every database queried, every external service touched. Timestamped, signed, immutable.

Transaction Evidence

Financial actions get first-class treatment. Amount, counterparty, authorization chain, all structured for auditors.

$4,200.00 → vendor:api-co → approved_by:policy_7

Access Patterns

What data did the agent touch? PII exposure, credential usage, scope violations. Flagged automatically.

pii_detected: false | scope: within_policy

How It Works
1

Instrument your agents

One SDK call captures decisions, tool usage, and transactions. Framework-agnostic. Works with LangChain, CrewAI, AutoGen, or custom agents.

2

Evidence accumulates

Every agent action is cryptographically signed and stored in an append-only ledger. Tamper-proof by design. Your auditors will appreciate this.

3

Generate compliance packages

Select a framework. Signet maps your agent activity to the specific controls and evidence requirements. Export audit-ready reports in minutes, not weeks.

65% of enterprises have no AI governance framework.
The auditors are coming anyway.

Signet turns your agent operations into compliance-ready evidence before anyone asks for it.
