Microsoft Teams: Copilot Chat for Teams Chats, Channels, Calling and Meetings

🚨 The Signal: Copilot Chat is expanding to all Teams interactions (chats, channels, calls, meetings). This increases the surface area for AI-driven data summarisation and content generation, impacting data governance and potential information exposure.

The Impact

All Teams users are affected, increasing the risk of sensitive information exposure through AI summarisation and content generation.

• End Users: Risk of oversharing sensitive data via AI summaries.
• Security Teams: Increased scope for data loss prevention (DLP) monitoring.
• Compliance Teams: New challenges in auditing AI-generated content for regulatory adherence.
• Admins: Need to review and enforce Copilot data governance policies across Teams.

The Action

1. Review and enforce Microsoft Purview Data Loss Prevention (DLP) policies for Teams and Copilot: https://compliance.microsoft.com/dlp
2. Audit existing Copilot for Microsoft 365 access and licensing to ensure least privilege: https://admin.microsoft.com/
3. Communicate updated acceptable use policies for Copilot in Teams to all users, emphasising data sensitivity.
4. Monitor Copilot usage reports in Microsoft 365 admin center for unusual activity or data access patterns.
