Microsoft 365 for Government and Defense Contractors

Commercial cloud software was not designed for government compliance. Microsoft 365 for Government delivers the full productivity suite your teams rely on inside a dedicated U.S.-based cloud infrastructure, with separate government cloud environments built to satisfy FedRAMP Moderate, FedRAMP High, ITAR, and DFARS requirements.

The Ponemon Institute's True Cost of Compliance report found that non-compliance costs organizations 2.71 times more than maintaining compliance. For government agencies and defense contractors, that gap translates directly into contract risk and audit exposure. eSoftware Associates has been deploying Microsoft 365 GCC and GCC High environments since 2006, with zero data loss across 200+ migrations and a 100% US-based team that handles every phase in-house.

Our Microsoft 365 Government and Defense Services

GCC for Federal, State, and Local Government Agencies

Microsoft GCC is the right cloud environment for most U.S. federal agencies; state, local, tribal, and territorial government agencies; and their approved contractors. It meets FedRAMP Moderate authorization requirements, enforces data residency by storing all data in U.S. data centers, and limits infrastructure access to screened Microsoft personnel.

Your teams get the Microsoft 365 collaboration tools they already know, including SharePoint for file sharing, Microsoft Teams, and Exchange, inside a cloud environment built to satisfy federal regulations. ESW manages the eligibility validation process alongside the full technical deployment so your organization never has to navigate compliance requirements alone.

Key services include:

Tenant eligibility review and validation
Tenant provisioning and environment setup
SharePoint, Teams, and Exchange configuration
Identity and access management
End-user onboarding and training

GCC High for Defense Contractors

For DoD contractors and organizations in the defense industrial base, Microsoft GCC High is a contractual requirement. If your work involves controlled unclassified information or sensitive data subject to International Traffic in Arms Regulations, Export Administration Regulations, or DFARS obligations, this is the environment your contracts demand.

Microsoft 365 GCC High meets FedRAMP. High standards with full separation from Azure commercial infrastructure, continuous monitoring, and access controls that far exceed the standard government cloud. ESW maps your compliance requirements before any configuration decision is made, ensuring the environment is built correctly from day one.

Key services include:

GCC High eligibility review and ITAR/DFARS compliance mapping
Tenant provisioning and separation from commercial infrastructure
CUI-aware SharePoint architecture and permissions
Secure Teams and Exchange deployment
Audit trail configuration and compliance documentation

Frequently Asked Questions (FAQ)

What is the difference between GCC and GCC High?

Microsoft GCC meets FedRAMP Moderate requirements and is designed for federal, state, and local government agencies and their approved contractors. Microsoft GCC High meets FedRAMP High, DFARS, and ITAR requirements and is required for organizations handling Controlled Unclassified Information or ITAR data. If your contracts include DFARS clauses or require access to DoD environments, GCC High is where you need to be.

How does my organization qualify for GCC or GCC High?

Eligibility must be validated through Microsoft’s Authorization Management Program before a tenant can be provisioned. GCC is available to U.S. government entities and approved contractors. GCC High requires DFARS obligations, ITAR requirements, or work involving CUI. The DoD’s CMMC 2.0 framework applies to 300,000+ organizations in the defense industrial base, making compliant cloud infrastructure a contractual prerequisite for most defense contractors.

Can we migrate existing Microsoft 365 data to GCC without losing anything?

Yes. Every ESW migration includes pre-migration assessment, compliance scoping, and validation checkpoints at each phase before go-live. Your data and existing configurations are protected throughout, and your organization remains operational during the move to a compliant cloud environment.

How long does a GCC or GCC High migration take?

Smaller environments can be completed in weeks. Government contractors moving into GCC High environments with extensive SharePoint, custom workflows, or on-premises infrastructure should plan for a multi-phase project. ESW provides a clear timeline during the discovery phase, so your team knows what to expect at every step.

Is Microsoft 365 Copilot available in government cloud environments?

Microsoft 365 Copilot is currently available in GCC for qualifying license tiers. Availability in GCC High environments is expanding on Microsoft’s published roadmap. AI-assisted outputs stay within your regulated tenant and do not leave the compliance boundary.

Does moving to GCC affect how our teams use Microsoft 365 day to day?

For most users, the experience is nearly identical to commercial Microsoft 365. Collaboration tools, including Microsoft Teams, SharePoint file sharing, and Exchange, work the same way. The primary differences are compliance controls, multifactor authentication requirements, and a slightly slower rollout of some new Microsoft features.

What support does ESW provide after go-live?

ESW provides full post-launch support, including environment optimization, ongoing consulting, and user training. This extends to tools across the Microsoft stack, including Microsoft Intune, Microsoft Sentinel, and Azure Information Protection. Our team remains available for continued support well beyond the initial deployment.

What is the difference between Office 365 Government and Microsoft 365 for Government?

Office 365 Government is an older licensing model largely superseded by Microsoft 365 for Government, which bundles core productivity apps with advanced security tools, including Microsoft Entra ID, Microsoft Intune, and Microsoft Sentinel. ESW helps organizations evaluate the right plan for their compliance requirements.
