Every agent action
leaves a record
you can prove.
AgentSigna gives enterprises a single control plane to authorize, sign, and audit what every AI agent does, before it touches a real system.
Every action case,
visible in one place.
From request through verdict to signed Passport: the full authorization lifecycle, tracked and auditable.
Not an agent builder.
Not a workflow tool.
A governance layer.
You already have the agents. What you're missing is a control plane that makes every action attributable, reviewable, and defensible.
AgentSigna sits between your agents and your business systems. It doesn't slow things down. It makes autonomous action something your leadership can stand behind.
- Plugs into any agentic framework, no platform lock-in
- Decisions recorded with cryptographic chain, not log files
- Policy engine belongs to your team, not our platform
- Built for auditors and security teams, not just developers
The control plane
for agentic action
Six primitives that make AI agent actions in enterprise workflows accountable, stoppable, and inspectable.
Trust-scored identities
Every machine actor carries a dynamic trust score that evolves with each real-world outcome. High-stakes actions from low-trust agents escalate automatically.
Org-owned policy engine
Write and version authorization rules in plain business terms. Approval thresholds, counterparty tiers, action categories, all configurable without touching infrastructure.
Cryptographic ledger
Every decision is chained to its predecessor. No selective deletion, no post-hoc editing. Bring the ledger to any audit: regulators, security teams, or legal counsel.
Sub-500ms decisions
AgentSigna sits in the critical path. Latency matters. Authorization verdicts return in under 500ms at p99. Your agents don't wait.
Multi-tenant isolation
Every organization's policies, agents, and ledger are hard-isolated. One platform can serve an entire enterprise division or a portfolio of portfolio companies.
Framework-agnostic API
One REST API. Works with LangChain, AutoGen, custom agents, or anything that can make an HTTP request. No SDK required, though one is provided.
Decision-makers who need
defensible AI
AgentSigna is for the people accountable when an AI agent does something wrong, not just the engineers who built the agent.
Procurement Leaders
AI agents are executing purchase orders and managing vendor relationships. You need a record proving every action was authorized, including who authorized it.
- Automatic escalation for high-risk vendors
- Signed audit trail for every PO
- Policy-driven approval routing
Security & Risk Teams
Agent sprawl is your new attack surface. AgentSigna gives a unified view of every machine actor's trust posture, with automatic flagging of anomalous behavior.
- Immutable event ledger, chain-verified
- Real-time counterparty risk classification
- Zero standing permissions by design
General Counsel
When regulators ask how your company authorized an AI-executed contract, you need more than logs. AgentSigna produces cryptographic receipts that hold up to scrutiny.
- Exportable, signed decision records
- Policy version history with timestamps
- Reviewer accountability at every step
Why teams buy
High-risk procurement actions stop being vague automation and become explicit business decisions, with a proof artifact attached.
