Every caller. One engine.

AI agents now make more decisions than your users do.

One authorization engine for users, services and AI agents. Every decision is centrally enforced, audited and explainable.

For platforms

User & workspace authorization

RBAC, ABAC, multi-tenancy, fine-grained permissions. Stop scattering if (user.role === "admin") across every controller.

workspace.member doc:* read
workspace.admin user:* invite
For workloads

Machine-to-machine authorization

Replace scattered, hardcoded authorization checks with one policy engine. Every internal API call gated the same way.

service:billing invoice:* read
service:webhook event:* publish
For AI agents

Agent tool gating

Every tool call is evaluated against policy before execution. Grant only the permissions an agent needs, only for as long as it needs them.

agent:gpt-sum doc:q4-* read · ttl 10m
agent:claude vault:* DENY
For multi-agent systems

Scoped delegation

Delegate only the permissions required for a task—never more. Delegated access can be scoped, time-limited and never exceeds the caller's own permissions.

orchestrator[scope:read] sub-agent
sub-agent db:* write · DENY (exceeds scope)

Decision log

Explain every authorization decision.

Every authorization decision includes who requested access, what was evaluated, which policy matched and why it was allowed or denied.

AI Explanation

checkout-service is granted read access to orders-api because it is directly assigned to the policy orders-read-access, which permits this action. The access path is direct, meaning no role or group membership was needed to resolve this permission.

Suggestion: No action is needed. If this access was unexpected, review the policy orders-read-access to confirm checkout-service should retain direct assignment.

Vengtoo secures Vengtoo. Every authorization decision in our own console is evaluated by the same Vengtoo Agent and authorization engine we ship to customers.

No internal bypasses. No special runtime. The same engine. The same agent. The same policies.
