Microsoft GCC & GCC High

    CUI Belongs in a Boundary You Can Point To.

    We plan, migrate, and manage Microsoft 365 GCC and GCC High for defense suppliers and public-sector teams — with the CMMC and DFARS evidence captured while we build, not scrambled for later.

    Not sure whether you need GCC High? Call (877) 777-6855 — that answer is free.
    You keep the written snapshot either way
    Two Environments

    GCC or GCC High. Pick it for the right reason.

    Most organizations are told to buy GCC High by someone who never scoped their data. The correct answer depends on whether you hold CUI, whether it is export-controlled, and what your contracts flow down.

    Microsoft 365 GCC

    US-sovereign cloud for state, local, tribal, and federal-adjacent organizations. Data residency in the continental US, screened US-person support, and FedRAMP High authorization behind the platform — without the licensing weight of GCC High.

    Microsoft 365 GCC High

    The environment defense contractors actually need for CUI and ITAR-controlled technical data. DFARS 252.204-7012 aligned, US-person-only operations, and the tenant boundary a C3PAO assessor expects to see when CUI touches email, Teams, or SharePoint.

    What We Do

    From eligibility call to managed sovereign tenant

    Eligibility and environment selection

    Commercial, GCC, or GCC High is a compliance decision with a six-figure tail. We validate your eligibility, map where CUI and ITAR data actually lives today, and give you a written recommendation you can defend to a prime, an auditor, or your CFO.

    Tenant build and migration

    Net-new tenant stand-up or migration from Commercial — mail, OneDrive, SharePoint, Teams, and identity. Cutover planned around your production calendar, with coexistence handled so nobody loses a mailbox on a Monday.

    CMMC-aligned configuration

    Conditional access, MFA, FIPS-validated encryption, audit logging, DLP, sensitivity labels, and external sharing controls — configured to the NIST 800-171 controls they satisfy, with the evidence captured as we go.

    Ongoing management and enclave support

    Day-two operations for a sovereign tenant: license management, US-person support, quarterly control review, and enclave design when only part of your business needs to live inside the boundary.

    What it actually buys you

    Keep CUI and ITAR-controlled data inside a US-sovereign, US-person-supported boundary
    Satisfy the DFARS 252.204-7012 cloud requirements your prime is asking about
    Raise your SPRS score with controls that are actually implemented, not planned
    Avoid over-buying GCC High when a scoped enclave or GCC will do
    Migrate off Commercial without breaking mail flow, Teams, or SharePoint links
    Walk into a C3PAO assessment with configuration evidence already assembled
    How We Work

    Assess. Build. Transform.

    01

    Assess

    Data-flow and scoping workshop: what CUI you hold, where it moves, who touches it, and which environment your contracts and export obligations actually require.

    02

    Build

    Tenant provisioning, identity and device design, migration waves, and control configuration mapped to NIST 800-171 — executed on a dated plan with rollback points.

    03

    Transform

    Steady-state management, evidence upkeep, annual reassessment, and roadmap work as scope, headcount, and contract requirements change.

    Find out which environment you actually need

    Bring us your contract language and a rough picture of where your data sits. We will tell you plainly whether GCC High is required, whether a scoped enclave is enough, and what the migration would involve.
