About Microsoft 365 GCC High
Microsoft 365 Government Community Cloud High (GCC High) is a highly secure, compliance-focused cloud productivity platform designed specifically for U.S. federal agencies and defense contractors that handle sensitive or regulated data, extending the core Microsoft 365 applications within a hardened, government-only environment. It runs on Azure Government infrastructure and is logically isolated from commercial Microsoft 365 environments, ensuring that all customer data is stored exclusively in U.S.-based data centers and accessible only by screened U.S. personnel, reinforcing strict data sovereignty and access controls. It is built to meet the most stringent regulatory standards, including FedRAMP High, DFARS, ITAR, CMMC, and Department of Defense security requirements, making it suitable for handling Controlled Unclassified Information (CUI) and other export-controlled or defense-related data.
