Microsoft Copilot (Microsoft 365): Suggestions for slide templates as you work

🚨 The Signal: Copilot in PowerPoint now suggests slide templates as users type, potentially exposing sensitive internal template structures or data if not properly governed. This increases the risk of inadvertent data leakage.

The Impact

All users leveraging Copilot in PowerPoint are affected, increasing the risk of sensitive information exposure through template suggestions.

• End Users: Risk of inadvertently using templates that expose sensitive data.
• Security Teams: Increased surface area for data exfiltration via template suggestions.
• Compliance Teams: New considerations for data handling policies and attestation.
• Administrators: Need to review Copilot data governance policies for template access.

The Action

1. Review and classify existing PowerPoint templates for sensitivity and access controls.
2. Implement or refine Microsoft Purview Data Loss Prevention (DLP) policies to detect and prevent sharing of sensitive template content.
3. Educate users on responsible use of Copilot template suggestions and data handling best practices.
4. Monitor Copilot usage logs for unusual template access or sharing patterns.
5. Configure Copilot content access policies to restrict template suggestions based on data sensitivity.
