What Is CMMC?
The Cybersecurity Maturity Model Certification (CMMC) is a Department of Defense framework designed to safeguard FCI and CUI across the Defense Industrial Base. It builds upon NIST SP 800-171 and introduces a structured model for assessing whether contractors have implemented appropriate cybersecurity controls.
Depending on contract requirements, organizations may be required to perform self-assessments or undergo third-party assessments conducted by a CMMC Third-Party Assessment Organization (C3PAO).
CMMC Levels Explained
Level 1 (Foundational)
Focuses on the protection of FCI. This level includes a subset of basic safeguarding requirements and is typically satisfied through annual self-assessment.
Level 2 (Advanced)
Addresses the protection of CUI and aligns directly with the 110 security requirements defined in NIST SP 800-171. Depending on contract sensitivity, this level may require either self-assessment or third-party assessment.
Level 3 (Expert)
Applies to a limited subset of contractors supporting critical national security programs. This level builds on NIST SP 800-171 and incorporates additional requirements from NIST SP 800-172.
CMMC Readiness & Advisory Services
Many defense contractors understand that CMMC is required but lack clarity on what “ready” looks like in practice. Requirements continue to evolve, internal teams are often resource-constrained, and documentation frequently lags behind implemented controls. At the same time, leadership is expected to make informed decisions before engaging a CMMC Third-Party Assessment Organization (C3PAO). Without clear guidance, organizations risk overengineering controls — or underpreparing for assessment.
RS Assurance & Advisory provides CMMC readiness and advisory services not certification.
Scoping & Assessment
We begin with CMMC scoping and applicability analysis to determine how requirements apply to your environment, including identifying where FCI and CUI reside and how they flow through systems. This is followed by structured gap assessments aligned to NIST SP 800-171 to evaluate your current control environment.
Control & Documentation Alignment
We support the development and refinement of policies and procedures to ensure they accurately reflect implemented controls and align with assessment expectations. Technical control validation and testing helps confirm safeguards are operating effectively and consistently.
Remediation & Readiness
We develop prioritized remediation plans focused on practical, risk-based improvements. As you approach assessment, we perform pre-assessment readiness reviews and provide ongoing support to help maintain compliance as requirements and environments evolve.
All services are advisory in nature and designed to prepare organizations for third-party CMMC assessments while preserving independence. Our approach prioritizes reducing uncertainty without introducing unnecessary risk.
Organizations we support typically handle FCI and/or CUI, operate as prime contractors or subcontractors, and require a defensible readiness posture before pursuing certification. This includes defense contractors, aerospace and manufacturing suppliers, engineering and R&D firms, IT and managed service providers supporting DoD programs, and software vendors serving federal customers.
