C3 Integrated Solutions —
CMMC Compliance & GCC High for Defense Contractors

C3 Integrated Solutions is not a generalist IT or security firm that added CMMC to a service menu — they are purpose-built around the defense industrial base compliance ecosystem. Every engagement is scoped around the specific requirements of organizations handling CUI under DoD contracts: CMMC, DFARS, NIST 800-171, and the associated cloud and documentation obligations. This specialization means fewer false starts, more accurate gap assessments, and documentation that holds up under C3PAO scrutiny.

A CMMC Level 2 assessment is fundamentally a verification of NIST 800-171 implementation. C3's gap analysis identifies exactly where the organization falls short across all 110 requirements, calculates the current SPRS score, and produces a prioritized remediation plan that addresses the highest-risk gaps first. For contractors with self-reported SPRS scores that may not withstand third-party scrutiny, this analysis is the critical first step to avoiding assessment failure.

Microsoft 365 GCC High is the required cloud environment for most DIB contractors handling CUI — and migrating from commercial Microsoft 365 is more complex than a standard tenant-to-tenant migration. GCC High has different identity infrastructure, licensing models, and compliance configurations. C3 Integrated Solutions has direct experience with GCC High migrations, including the Azure AD tenant federation, licensing procurement, and data migration sequencing that determine whether the migration satisfies DFARS requirements.

The System Security Plan and Plan of Action and Milestones are the two documents that assessors spend the most time reviewing during a CMMC Level 2 assessment. Poorly written, incomplete, or inaccurate SSPs are one of the most common reasons companies fail or receive significant findings during assessment. C3 produces SSPs and POA&Ms that accurately reflect the organization's actual control implementations — not aspirational descriptions — ensuring the documentation survives assessor scrutiny.

CMMC certification is not a one-time event — contractors must maintain compliance between assessment cycles. C3's managed IT and SOC services are designed to sustain the control implementations that earned certification: continuous monitoring evidence, patch management records, access control logs, and incident response documentation. This ongoing operational layer prevents compliance drift and ensures the organization remains assessment-ready at any point during the certification period.
