Microsoft Purview: Data Loss Prevention - Data Loss Prevention to safeguard sensitive information from external web search in Microsoft 356 Copilot and Copilot Chat

🚨 The Signal: Microsoft Purview DLP now prevents Microsoft 365 Copilot and Copilot Studio agents from using sensitive data in external web searches. This mitigates data leakage risks by enforcing real-time content scanning before external queries.

The Impact

Security teams and Copilot users are affected by enhanced data loss prevention, reducing the risk of sensitive data exposure via AI-driven web searches.

• Security Teams: Reduced risk of sensitive data exfiltration by AI agents.
• Copilot Users: Web searches containing sensitive data will be blocked.
• Compliance Officers: Improved adherence to data protection policies for AI interactions.
• AI Developers: Need to consider DLP policies when designing Copilot Studio agents.

The Action

1. Review existing Microsoft Purview DLP policies to ensure they cover sensitive information types relevant to Copilot interactions.
2. Educate Copilot users on DLP policies and how to avoid triggering blocks during web searches.
3. Monitor DLP alerts related to Copilot and Copilot Chat to identify potential policy gaps or user training needs.
4. For Copilot Studio agents, ensure developers are aware of and test against Purview DLP policies.
