(Updated) PowerPoint for Windows desktop: "Review this presentation" skill in Copilot

🚨 The Signal: Copilot in PowerPoint now offers a 'Review this presentation' skill, leveraging Anthropic and GPT-5.5 models. This enhances content generation capabilities, increasing the risk of sensitive data exposure through AI processing if not properly governed.

The Impact

Users with PowerPoint Copilot are affected, increasing the risk of inadvertent data exposure or intellectual property leakage through AI processing.

• End Users: Risk of exposing sensitive presentation content to AI models.
• Security Team: Increased need for data governance and AI interaction monitoring.
• Compliance Officers: Potential for non-compliance if sensitive data is processed by external AI.
• IT Admins: No direct control over individual Copilot skills, limiting granular security enforcement.

The Action

1. Review and enforce Microsoft Purview Data Loss Prevention (DLP) policies for PowerPoint content.
2. Educate users on responsible AI use, emphasizing not to input sensitive or classified information into Copilot.
3. Monitor Microsoft 365 audit logs for Copilot interactions involving sensitive data types.
4. Assess existing data classification and labelling policies for their applicability to AI-generated content.
