Microsoft Copilot (Microsoft 365): [Copilot Extensibility] Improved discovery of Copilot connector sources in Microsoft 365 Copilot (optionally add chat) with Content Source filter(s)

🚨 The Signal: Copilot now offers improved content source filtering for connectors, making it easier for users to find information from integrated third-party services. This enhances data discovery but requires careful governance of connector access and data exposure.

The Impact

All Copilot users are affected; the risk is unintended data exposure if connector access isn't properly governed.

  • Security Teams: Risk of data overexposure if connector permissions are not tightly controlled.
  • Admins: Increased need to review and manage Copilot connector configurations and data access policies.
  • End Users: Improved data discovery, but potential for seeing data from sources they shouldn't access if policies are lax.

The Action

  1. Review existing Copilot connector configurations and their associated data access policies.
  2. Implement or refine data loss prevention (DLP) policies for data exposed via Copilot connectors.
  3. Audit user access to third-party applications connected to Copilot via connectors.
  4. Educate users on appropriate data handling when interacting with Copilot and its connected sources.
