If an AI browser works across my logged-in apps, does it inherit all of my permissions?

No. Authentication of the employee is not authority for the agent. Access to business applications does not mean an AI operating through that session inherits those powers. Nothing the agent learns increases what it is authorized to cause.

Deployment scope is determined during evaluation. Hood does not prove that AI will always be safe.

If this problem matches your environment, START with the systems, effects and authority boundary you need to control.
