Protect your
boundary.

Autonomous software moves fast. Control stays ahead.

SCROLL TO OPEN

Permissions are static.
Agent behavior is not.

Access lists know what an identity can usually reach. Ostrelio evaluates whether this exact action should happen now.

Identity establishes the actor.
Runtime authorization governs the act.

Individually safe.
Collectively dangerous.

Most authorization systems evaluate API calls independently. Ostrelio reads the whole execution chain.

Permission follows
the task.

Authority stays attached to the delegated objective—not just the agent identity or API scope.

AI can increase caution.
It cannot override policy.

Contextual intelligence can escalate a decision. Deterministic company rules remain immutable.

Contextual risk can escalate an allow to a required approval; it cannot loosen a signed priority-0 rule.
