The platform
Signet is the non-bypassable authorization layer that decides whether an AI agent is allowed to act. It owns identity, trust, authority, governance, and auditability — so autonomous systems can be trusted at scale. Nothing runs until Signet says yes.
The control plane
Signet is the system that determines whether an AI agent should be allowed to act — right now, in this context, with this authority.
A persistent identity for every agent that survives models, sessions, and systems — anchored to a cryptographic root that can be revoked in an instant.
Authority is continuously earned, adjusted, and enforced over time, not granted once and forgotten.
Policies, roles, boundaries, and compliance enforced in real time at the moment of action.
An immutable, hash-chained record of every significant action and decision — provable after the fact.
A deterministic pass, block, or hold on every tool call — evaluated with no model call, so overhead is ~1x.
Swap or upgrade the underlying model without losing identity, trust, or continuity.
How it works
Signet sits at the point of execution — between the agent deciding and the action happening — and it is not optional in the path.
1 · Onboard
Each agent is born with a mandate: its role, scope, and hard limits, set by the enterprise and fixed before it acts.
2 · Enforce
Every tool call is evaluated against the mandate and live context. Legitimate actions pass, unauthorized actions are blocked, and anything that needs a human gets a provable hold.
3 · Prove
Every allow and deny is written to an append-only, hash-chained ledger. The chain is intact and independently checkable — complete lineage for any agent.
See it in action
Signet gives every agent a runtime identity at birth — an anchor, a canon, and a sealed genesis deed. Try the interactive birth tool: pick a sector and an agent, and watch its identity, weighting, and first deed come into being. Then load a rogue and see the difference.
The outcome
Prevent unauthorized actions, privilege creep, and policy violations before they execute.
Complete lineage, explainability, and auditability for regulated environments.
Govern thousands to millions of agents with consistent, enforced guardrails.
Identity and governed context live in Signet, so the model re-carries less on every call — fewer tokens, clearer cost.
