Copilot doesn't create new permissions.
It removes friction.
Microsoft 365 Copilot does not introduce new access rights. However, it fundamentally alters the data exposure model by removing the friction that historically limited access to information.
Content that was technically accessible but practically undiscoverable becomes immediately retrievable through natural language queries. Legacy access, overshared sites, public Teams, historical group membership, and unlabelled sensitive content all become active exposure vectors the moment Copilot is enabled.
"This materially changes the organisation's risk profile. The question is not whether to adopt Copilot — it's whether the organisation can evidence the governance controls necessary to do so responsibly."
