Microsoft 365 Business Premium Now Available for GCC High

The launch of Microsoft 365 Business Premium for GCC High marks a significant milestone for government contractors and organizations handling sensitive data in highly regulated environments. With this new offering, Microsoft extends its enterprise-grade security and compliance features to businesses with up to 500 users, providing a tailored cloud solution designed to meet the stringent requirements of the U.S. government and Defense Industrial Base.

What Is GCC High?

GCC High is a specialized cloud environment designed exclusively for U.S. federal agencies, defense contractors, and organizations working with Controlled Unclassified Information (CUI), ITAR, and other sensitive government data. It offers physical data isolation within U.S. borders and restricts access to vetted U.S. persons, ensuring compliance with the most rigorous government security standards. This environment is governed by strict cybersecurity mandates, including the Cybersecurity Maturity Model Certification (CMMC), which contractors must adhere to in order to participate in government contracts.

Why Business Premium Matters for GCC High

Previously, small and midsize businesses working under these regulations often faced challenges balancing cost, complexity, and compliance. Many had to opt for larger enterprise plans like Microsoft 365 E5, which, while comprehensive, could be financially and operationally burdensome. The introduction of Business Premium for GCC High changes this by offering a cost-effective, streamlined solution tailored for organizations with fewer than 500 seats, without compromising on security or compliance capabilities.

Key Features

• Access to familiar Microsoft 365 apps (Word, Excel, PowerPoint, Outlook).

• Advanced security features designed for government regulations.

• Compliance tools to streamline CMMC, ITAR, and other mandates.

• Secure data storage and sharing limited strictly to other GCC High and DoD tenants.

• Enterprise-grade protections, including Microsoft Defender and Information Protection.​

• Designed and priced for organizations with fewer than 500 seats.

Compliance and Security Benefits

This new plan empowers smaller organizations in the defense supply chain to comply with federal cybersecurity mandates cost-effectively. It provides a trusted platform where sensitive government data can be securely accessed, shared, and protected, reducing risk while meeting regulatory requirements. For many, Microsoft 365 Business Premium for GCC High is the crucial link that allows them to confidently compete for government contracts without sacrificing security or compliance.
