CMMC vs SOC 2 vs FedRAMP: Cost, Scope, and Requirements Compared

Many defense contractors and cloud providers need multiple compliance frameworks. This comparison covers cost, controls, timelines, and overlap so you can plan a unified compliance strategy.

CMMC vs NIST 800-171

CMMC Level 2 and NIST SP 800-171 Rev 2 share the exact same 110 security controls across 14 families. The critical difference is verification. Under NIST 800-171, compliance was self-attested through a SPRS score. Under CMMC, a certified third-party assessor (C3PAO) verifies your implementation. This means organizations already compliant with NIST 800-171 primarily face the added cost of the C3PAO assessment ($30,000 to $200,000) rather than implementing new controls.

The practical impact: if your SPRS score honestly reflects your security posture and you have evidence to support it, CMMC adds process cost (assessment fees, evidence packaging) rather than technical cost (new tools, new controls).

CMMC vs FedRAMP

CMMC and FedRAMP serve different audiences. CMMC applies to defense contractors protecting CUI on their own systems. FedRAMP applies to cloud service providers (CSPs) offering services to federal agencies. Some organizations need both: a CSP selling to DoD may need FedRAMP for their cloud platform and CMMC for their corporate environment.

FedRAMP is substantially more expensive ($250K to $3M initial) because it assesses the security of a cloud platform, not just an organization. The control count is higher (325+ for Moderate, 421 for High), the assessment is more rigorous, and continuous monitoring requirements are stricter.

CMMC vs SOC 2

SOC 2 is a market-driven framework for demonstrating security to commercial customers. CMMC is a government mandate for handling DoD data. Many defense contractors have both commercial and government clients, making both frameworks relevant.

SOC 2 is generally cheaper ($50K to $150K initial) and faster (6 to 12 months). The good news for dual-framework companies: approximately 30% to 40% of CMMC Level 2 controls overlap with SOC 2 Trust Services Criteria, particularly in access control, audit logging, and risk assessment. If you have SOC 2, your CMMC remediation scope is reduced. Explore detailed SOC 2 pricing at SOC2ComplianceCost.com.

Frequently Asked Questions

If I have SOC 2, do I still need CMMC?
Yes. SOC 2 and CMMC serve different purposes and different audiences. SOC 2 demonstrates trust to commercial customers. CMMC demonstrates compliance to the Department of Defense. However, having SOC 2 gives you a significant head start. Approximately 30% to 40% of CMMC Level 2 access control and audit practices overlap with SOC 2 Trust Services Criteria. You will not start from zero, but you will need to address the DoD-specific controls that SOC 2 does not cover (CUI handling, FIPS encryption, SPRS scoring).
Which is more expensive, CMMC or FedRAMP?
FedRAMP is significantly more expensive. FedRAMP authorization typically costs $250,000 to $3,000,000 for the initial assessment, compared to $50,000 to $500,000 for CMMC Level 2. FedRAMP annual maintenance runs $200,000 to $500,000 versus $30,000 to $120,000 for CMMC. FedRAMP is for cloud service providers selling to the federal government. CMMC is for defense contractors handling CUI. Some organizations need both.
Does NIST 800-171 compliance equal CMMC Level 2?
CMMC Level 2 requires the same 110 controls as NIST SP 800-171 Rev 2. The difference is enforcement. NIST 800-171 was self-attested with a SPRS score. CMMC adds mandatory third-party verification through a C3PAO assessment. If you are already compliant with NIST 800-171 and can prove it with evidence, CMMC Level 2 primarily adds the cost of the C3PAO assessment ($30,000 to $200,000), not a new set of controls.
