TACTICAL BRIEFING FAQ

Why is the Commercial Cloud insufficient for ITAR/CUI data?

Commercial clouds utilize a global ‘Follow-the-Sun’ support model, allowing non-U.S. engineers to access infrastructure for maintenance. This constitutes a direct violation of ITAR and EAR regulations. GCC High Comparison guarantees strict CONUS data residency and is supported exclusively by screened U.S. Persons.

What is the estimated timeline for validation and migration?

Eligibility validation with Microsoft typically requires 5-10 business days. The technical migration timeline varies by data volume, but a standard ‘Tenant-to-Tenant’ deployment cycle ranges from 30 to 60 days to ensure zero data loss and full operational integrity.

Does GCC High automatically grant CMMC Level 2 Certification?

Not automatically, but it is the mandatory foundation. GCC High Comparison provides the required sovereign infrastructure. On top of this layer, we configure the specific NIST 800-171 security controls required for your organization to pass CMMC Level 2 or Level 3.

Will there be operational downtime during the migration?

Minimal. We execute a ‘Background Synchronization’ strategy. Your emails and files are replicated while your team continues to work. The final ‘Cutover’ is strategically scheduled outside of operational hours (typically weekends) to ensure mission continuity.
