AgentSignaBuilt around the moment
a machine is about to
commit something important.
AgentSigna sits between your agents and your business systems. It decides whether an action is allowed, when it must go to a human, and what proof must exist for everything that proceeds.
Machine Actor Registry
Every AI agent that touches your business systems carries a registered identity: a sponsor, a risk tier, and a trust score that evolves from real outcomes. No anonymous agents. If it acts, it has a name and an owner.
When something goes wrong, you know exactly which agent did it, who owns it, and what authority it held at the time.
Policy Engine
Your organization writes and owns the rules that govern agent behavior. Which actions require approval, at what thresholds, in which counterparty contexts. The engine belongs to your team, not our platform configuration.
When an auditor asks why an action was allowed, you can point to the exact rule and when it was last changed.
Approval Queue
When policy thresholds require it, the action enters a structured queue with full context attached: actor identity, trust score, payload, counterparty risk, and the exact rule that triggered escalation. Approvers decide with evidence, not instinct.
The approval itself becomes part of the permanent record. No guessing, no off-the-record decisions.
Hash-Chain Ledger
Every event in an action case is linked cryptographically to the one before it. There is no way to delete or modify a single entry without breaking the chain. The record is append-only by construction, not by policy.
You can bring the ledger to an external audit. Its integrity is mathematically verifiable, independent of your word or ours.
Trust Profile Learning
Outcomes feed back into trust scores continuously. Agents with consistently good results earn more operating latitude. Agents involved in reversed or disputed actions lose it. The system calibrates from what actually happened.
Authorization decisions improve over time without manual reconfiguration.
Proof of authority
Signed Action
Passport
Authorized actions receive a cryptographically signed Passport before they execute. It carries the full decision record and cannot be altered after issuance. Any downstream system can verify it without calling back to the platform.
Any auditor can verify a specific action was authorized, without having to trust your word for it.
Before, during,
and after every action
Before
Underwrite authority
Policy, trust, and thresholds are evaluated at decision time. Not after the fact when the damage is already done. Every request starts with zero authority. It has to earn its way through.
During
Route explicit approval
Humans enter the loop only when business rules require it, with the full context attached. Not a bare notification. The approver sees exactly what triggered escalation and why.
After
Carry proof forward
Signed records and replay history make every decision inspectable indefinitely. By your internal team tomorrow, or by a regulator two years from now.
The narrow promise
AgentSigna doesn't orchestrate your agents or replace your workflows. It governs the specific moment where a machine is about to commit something that matters, and makes that moment explicit, signed, and permanent.
