The rollout of CMMC 2.0 has changed how federal contractors approach cybersecurity. Now more than ever, if you handle Controlled Unclassified Information (CUI), your cloud environment plays a direct role in your ability to win or retain government contracts. Enter Microsoft GCC High—the only Microsoft 365 environment built to meet the rigorous demands of CMMC Level 2 and above.
Here’s what you need to know about aligning CMMC 2.0 compliance with GCC High migration services.
1. CMMC 2.0 Has Tightened Requirements
Under the new model:
Level 2 requires third-party assessments for contractors handling CUI
Self-assessments are limited to select programs
Compliance is tied directly to contract eligibility
This means organizations must prove—not just claim—that they have strong security controls in place.
2. GCC High Meets the Infrastructure Needs for Level 2
CMMC Level 2 is based on NIST SP 800-171, which outlines 110 required controls. GCC High:
Provides U.S.-based data residency and support
Enforces strong identity and access management (IAM)
Offers advanced audit logging and monitoring
Integrates with Microsoft Purview and Defender for enhanced data protection
Trying to meet CMMC Level 2 in a commercial M365 tenant is difficult—often impossible.
3. Assessors Are Looking for Tenant Alignment
C3PAOs and DoD auditors will assess your environment’s ability to:
Isolate CUI
Enforce encryption
Log access and monitor anomalies
Prevent unauthorized data sharing
GCC High provides the compliant foundation necessary to demonstrate these capabilities during formal assessments.
4. Documentation and Policy Still Matter
Migrating to GCC High doesn’t automatically make you CMMC compliant. You’ll also need:
System Security Plans (SSPs)
Plan of Actions and Milestones (POA&Ms)
User training and awareness programs
Internal audit and remediation plans
✅ Expert GCC High migration services help align your technology with your documentation to present a full compliance picture.
5. Early Migration = Competitive Advantage
Many competitors are still scrambling to prepare. Migrating early to GCC High:
Shows maturity to primes and contracting officers
Enables faster compliance assessments
Reduces risk of audit failure or bid rejection
It’s not just about meeting the minimum—it’s about being ready before the deadline.
