We’re excited to announce the availability of Microsoft 365 Business Premium for GCC-High. This purpose-built productivity suite is designed for organizations with high security and compliance requirements and supports up to 500 seats. 

Stay compliant without compromise 

With the Department of War (DoW) introducing new CMMC compliance requirements for contractors and subcontractors, organizations across the defense supply chain are navigating heightened security and compliance expectations. Microsoft 365 Business Premium  for GCC-High provides a cost-effective path for smaller organizations— such as component manufacturers and service providers— to meet these requirements without sacrificing agility or affordability. This suite ensures that even the smallest suppliers can maintain the security and compliance standards necessary to continue doing business in a highly regulated environment. 

Enterprise-grade security, simplified for you 

Microsoft is actively responding to these new mandates by delivering solutions that simplify compliance and strengthen security. Microsoft 365 Business Premium for GCC-High combines familiar Microsoft 365 apps with advanced security features and compliance tools, enabling organizations to protect sensitive data, streamline operations, and stay aligned with government regulations. By delivering enterprise-grade capabilities in a streamlined offering, we enable smaller organizations to meet CMMC requirements and remain competitive. This approach ensures they have the security, compliance, and productivity tools needed to operate confidently in regulated environments. 

Built for small teams with big impact 

Microsoft 365 Business Premium for GCC-High is designed for organizations with fewer than 500 seats. Larger organizations are encouraged to explore our Microsoft 365 Government offerings, which provide additional scalability and advanced capabilities. 

Roadmap 

These milestones reflect our commitment to empowering government organizations with secure, compliant productivity tools. Additional capabilities, like Copilot Studio extensibility, are planned for future releases. For the latest updates on new capabilities coming to GCC-High, refer to our roadmap.

    Are there any other official notifications about this offering. I see how it will benefit the customers.  Does it include everything that the commercial side does?

      Do you mean you are in commercial and want to move to GCCH?

    GCC-H for all of Win365 VM + BizPremium + E5 Security Add-on would be a key Enclave product.

    Is this just a new license structure or is this an entirely new tenant structure? If we already have a GCC-H tenant with G5 licenses and such, would we just be purchasing a different license instead of the G5?

      I had been told the same thing as recently as last week so I am extremely interested if this license count is confirmed.
