Compliance Framework Comparison.
Analysis
Four frameworks compared across every dimension. Which one your organization needs depends on who you sell to, what data you handle, and where you operate.
Overview
Framework Summary
Each framework serves a different audience, regulatory body, and compliance objective. Some organizations need one. Many need several. The federal frameworks anchor to the NIST Cybersecurity Framework, while service organization audits follow the AICPA SOC 2 Trust Service Criteria.
Cybersecurity maturity for defense contractors handling CUI.
Best for: Defense Industrial Base contractors with DFARS 252.204-7012 clauses.
CMMC Level 2 details →Security authorization for cloud services used by federal agencies.
Best for: Cloud service providers selling to federal agencies.
FedRAMP Moderate details →Trust service criteria for service organizations processing customer data.
Best for: SaaS providers, managed service providers, and data processors.
SOC 2 Type II details →Information security management system standard recognized globally.
Best for: Organizations with international customers or operating in multiple countries.
ISO 27001 details →Detailed Comparison
Full Comparison Matrix
Twelve dimensions compared across all four frameworks. Scroll horizontally on smaller screens.
| Dimension | CMMC Level 2 | FedRAMP Moderate | SOC 2 Type II | ISO 27001 |
|---|---|---|---|---|
| Governing Body | Department of Defense (DoD) | GSA / FedRAMP PMO | AICPA | ISO / IEC |
| Primary Audience | Defense Industrial Base contractors | Cloud service providers to federal agencies | Service organizations processing customer data | Any organization managing information security |
| Control Source | NIST 800-171 rev2 (110 practices) | NIST 800-53 rev5 (Moderate baseline) | AICPA Trust Service Criteria | ISO 27001:2022 Annex A |
| Number of Controls | 110 practices across 14 domains | 325 controls across 20 families | ~60 criteria across 5 trust categories | 93 controls across 4 themes |
| Assessment Type | Third-party (C3PAO) for Level 2 | Third-party (3PAO) plus agency ATO | Independent CPA firm audit | Accredited certification body audit |
| Assessor Organization | CMMC Accreditation Body (Cyber AB) | A2LA-accredited 3PAOs | Licensed CPA firms | ANAB, UKAS, or equivalent accredited CBs |
| Certification Period | 3 years with annual affirmation | 3 years with continuous monitoring | 12-month observation period per report | 3 years with annual surveillance audits |
| Continuous Monitoring | Annual affirmation required; DIBCAC spot checks | Monthly vulnerability scans, annual assessments, ConMon deliverables | Not required between audit periods | Annual surveillance audits; internal audits required |
| Geographic Scope | United States (DoD contracts) | United States (federal agencies) | Global (commonly US-originated) | Global (160+ countries recognize) |
| Industry Focus | Defense contractors handling CUI | Cloud providers serving government | SaaS, fintech, healthcare, managed services | Cross-industry; enterprise, finance, technology |
| NIST 800-53 Overlap | High (NIST 800-171 derives from 800-53) | Direct (800-53 is the control catalog) | Moderate (mappable but different structure) | Moderate (ISO 27002 maps to 800-53 families) |
| When to Pursue | Bidding on DoD contracts with DFARS 7012 clauses | Selling cloud services to federal agencies | Customers requesting trust assurance; enterprise sales | International markets; global customer base; EU operations |
Government Stack
CMMC, FedRAMP, and NIST 800-53 all derive from the same federal control catalogs. Defense contractors handling CUI often need CMMC plus FedRAMP if they sell to civilian agencies. The control overlap is real; the assessment processes are distinct.
Commercial Stack
SOC 2 and ISO 27001 serve SaaS providers and global organizations. Customers ask for SOC 2 first; international expansion adds ISO 27001. The two frameworks overlap meaningfully on access control, change management, and incident response, so building once and proving twice is the cost-efficient path.
One Posture, Many Proofs
Organizations rarely need just one framework. A defense contractor with commercial SaaS customers needs CMMC, FedRAMP, and SOC 2 simultaneously. Maintaining each as a separate compliance program multiplies cost; building a unified security posture and proving against each framework on demand replaces duplication with leverage.
