Frequently Asked Questions
What is GCC and GCC High?
GCC (Government Community Cloud) and GCC High are specialized versions of Microsoft 365 designed for U.S. government agencies, defense contractors, and organizations that must meet strict compliance standards. GCC High offers additional protections and is required for handling Controlled Unclassified Information (CUI) and meeting DFARS, ITAR, and CMMC Level 2/3 requirements.
Who needs GCC High instead of GCC?
GCC High is typically required for DoD contractors, aerospace and defense organizations, and companies handling export-controlled data. If your contract includes CUI, ITAR, or DFARS 7012 clauses, you likely need GCC High to stay compliant.
How does Jun Cyber help with GCC and GCC High?
We help businesses determine whether GCC or GCC High is the right solution, assist with licensing and tenant setup, migrate data securely, and configure the environment to meet NIST 800-171, CMMC, and FedRAMP Moderate/High requirements.
Can Jun Cyber migrate my existing Microsoft 365 environment to GCC High?
Yes. We handle secure migrations from Commercial Microsoft 365 to GCC or GCC High, including email, SharePoint, OneDrive, Teams, and other workloads. Our process minimizes downtime and ensures data remains protected during the transition.
How does GCC High improve security?
GCC High uses data residency within U.S. sovereign environments, screened personnel, and FedRAMP High controls to protect sensitive data. This provides stronger security and compliance than commercial Microsoft 365 environments.
How much do GCC High licenses cost?
GCC High licenses are more expensive than standard Microsoft 365 plans because of their higher security requirements. Jun Cyber helps you choose the right licensing mix to control costs while staying fully compliant.
