EXECUTION AUTHORIZATION

Execution authorization stack

TrigGuard is execution authorization infrastructure for agents and automation: SDKs reach a runtime authorization gateway; connector-bound deployments add an execution proxy so PERMIT / DENY / SILENCE runs before side effects. Receipts are signed; verification is independent.

Model governance decides whether a model may be deployed. Execution authorization decides whether a specific action may run.

That is the category line TrigGuard implements at the tool boundary.

AI CONTROL STACK

TrigGuard is a cloud-neutral pre-execution authorization layer. In the six-layer operating model, it sits after execution infrastructure and before observability and compliance.

NO PERMITNO EXECUTION

ARCHITECTURE

Authorization Before Execution.

TrigGuard evaluates intent against deterministic policy before irreversible actions occur. Built for a world where AI agents move fast-and need a hard safety interlock.

NO PERMIT, NO EXECUTION.

Core Architectural Properties.

Deterministic

Every request produces exactly one outcome based on active policy. No probabilistic guessing.

Fail-Closed

If the authorization cannot be confirmed, execution is blocked by default. Safety first.

Verifiable

Every decision is cryptographically signed (Ed25519) and can be verified offline at any time.

Integration Paths.

SDK / Middleware

Deep integration into Node.js or Python application code.

Sidecar Proxy

Infrastructure-level proxy for outbound tool and API calls.

Execution Gateway

Centralized REST API for all agentic authorization requests.

TRUST

Independent Verification.

Because every receipt is signed with an Ed25519 private key, you can verify authorization without ever calling TrigGuard's API again.

# Verify a receipt offline
trigguard verify ./receipt.json --public-key ./authority.pub
FAQ

Architectural Details.

What is the added latency? +
Decisions typically take < 15ms. The majority of this is signature generation. Policy evaluation is performed in-memory against a compiled representation.
What happens if TrigGuard is offline? +
TrigGuard is designed for high-availability. However, the system is strictly fail-closed. If the authorization layer is unreachable, the request is denied.
Can I host my own Arbiter? +
Yes. Enterprise customers can deploy the Arbiter as a native sidecar or containerized service within their own VPC for maximum security and performance.
