Agent Identity
Know which autonomous actor is requesting execution. Every transaction carries agent ID, tenant, and environment, evaluated at runtime.
Platform
An Execution Control Plane for AI Agents
Access control answers WHO. VetoPlane governs WHAT HAPPENS.
Tool Registry
Control which tools and immutable tool versions an agent can invoke. Policy decisions cannot silently change because a downstream schema changed.
Deterministic Policy
Evaluate execution against explicit business and security rules. Allow, require approval, or deny at the transaction level, not the session level.
Human Approval
Transaction-bound approval gates for high-risk actions. Approval is tied to the exact execution ID, arguments, tool version, and policy version, single-use and expiring.
Runtime Protection
Rate limits, agent suspension, configuration freshness, fail-closed enforcement, and replay protection. Control the execution plane in real time.
Execution Ledger
Every agent action creates an immutable execution record: who acted, what was attempted, which policy decided, what approval existed, and what actually executed downstream.
Tenant Isolation
Execution context and policy boundaries remain isolated across tenants and environments. One agent cannot affect another tenant's execution path.
