Microsoft Copilot (Microsoft 365): Microsoft 365 Copilot Chat - General Availability for the GCC High environment

🚨 The Signal: Microsoft 365 Copilot Chat is now generally available in GCC High with web grounding disabled by default. This prevents sensitive US government data from leaving the GCC High compliance boundary, enhancing data residency and protection.

The Impact

US government users in GCC High are affected, with a reduced risk of sensitive information exposure outside the compliance boundary.

• US Government users: Copilot Chat is available, but web search is off by default.
• Security teams: Reduced risk of data exfiltration from GCC High.
• Compliance officers: Enhanced data residency and compliance posture.
• IT administrators: No immediate action required, but awareness of default setting is key.

The Action

1. Review existing Copilot governance policies for GCC High environments.
2. Communicate default web grounding setting to GCC High users.
3. Assess if web grounding needs to be enabled for specific use cases, understanding the data implications.
4. Monitor Copilot usage within GCC High for compliance with data handling policies.
