Microsoft verifies your organization qualifies for GCC or GCC High before any license can be issued.
Licensing is purchased through an authorized Cloud Solution Provider, not the commercial self-service portal.
A dedicated government-community tenant is stood up, separate from any existing commercial tenant.
Mail, files, and identities move into the new tenant on a schedule that fits how your team actually works.
All three run in the same government-community cloud family; the difference is how much of the Microsoft 365 stack you need.
Email, Teams, and endpoint management for smaller contractors handling FCI only.
Full Microsoft 365 stack for larger public-sector-adjacent organizations, still commercial-equivalent compliance.
The tier required once CUI or ITAR data is in scope, with the DoD-aligned compliance baseline.
Authorized government cloud licensing partner
Eligibility validated before you commit to a tier
Migration planned around how your team actually works
Same team that builds your Secure Enclave and CMMC program
If you store, process, or transmit CUI or ITAR-controlled technical data, you need GCC High. If you only handle FCI or need FedRAMP-moderate alignment, GCC is usually sufficient. We validate this against your actual data, not a guess.
No. GCC High requires an authorized Cloud Solution Provider and an eligibility screening process; it isn't available through the commercial self-service portal.
Typically 1 to 3 weeks, depending on how quickly your organization's documentation (SAM registration, NAICS codes, entity structure) is available.
A small number of third-party integrations and preview features lag behind the commercial cloud. We flag any that affect your specific stack during the eligibility and planning phase.
