Is Microsoft Copilot available in GCC High?

Microsoft 365 Copilot became generally available in GCC High in December 2025, bringing AI-powered capabilities to Word, Excel, PowerPoint, Outlook, and Teams within the GCC High compliance boundary. All data is processed and stored in U.S.-based data centers managed by screened U.S. personnel.

Copilot in GCC High ships with web grounding turned off by default, which prevents the AI from accessing public web sources and keeps all prompts and responses inside the compliance boundary. Organizations can choose to enable web grounding where appropriate. Copilot Chat with the ability to reason over uploaded files is included with eligible Microsoft 365 plans, while the full Microsoft 365 Copilot license adds deeper Work IQ integration across apps. Wave 2 features, including expanded model access, image generation, a code interpreter for data analysis, and a research agent, are expected to roll out in the first half of 2026. Security Copilot, a separate product, is not currently available in GCC High. Organizations considering Copilot should review their data governance, permissions model, and sensitivity labeling before enabling it, because Copilot surfaces information based on existing user access permissions
