CMMC
DoD framework certifying DIB cybersecurity maturity levels
ISO 27701
International standard for privacy information management systems
Quick Verdict
CMMC mandates cybersecurity certification for DoD contractors protecting FCI/CUI via tiered assessments, while ISO 27701 provides voluntary PIMS framework for global privacy governance of PII. DoD firms adopt CMMC for contracts; others use 27701 for compliance and trust.
CMMC
Cybersecurity Maturity Model Certification (CMMC) 2.0
Key Features
- Three cumulative certification levels for FCI/CUI protection
- NIST SP 800-171/172 aligned controls with verification
- C3PAO third-party and DIBCAC government assessments
- Limited POA&Ms requiring 180-day closures
- Mandatory supply chain flow-down requirements
ISO 27701
ISO/IEC 27701:2025 Privacy Information Management
Key Features
- Stand-alone PIMS extendable from ISO 27001 ISMS
- Role-specific controls for PII controllers/processors
- Annex mappings to GDPR and other regulations
- Risk-based privacy assessments and DPIAs
- Three-year certification with annual surveillance audits

CMMC Details
What It Is
Cybersecurity Maturity Model Certification (CMMC) 2.0 is a U.S. DoD certification program verifying cybersecurity protections in the Defense Industrial Base (DIB). It safeguards Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) via three tiered levels and prescribed assessments, mapping to FAR 52.204-21, NIST SP 800-171 Rev 2, and NIST SP 800-172.
Key Components
- **Three cumulative levelsLevel 1 (17 basic FAR safeguards), Level 2 (110 NIST 800-171 controls), Level 3 (+24 NIST 800-172 enhancements).
- 14 domains (e.g., Access Control, Incident Response, Risk Assessment).
- Assessment via self-assessments, C3PAO, or DIBCAC; SSPs, POA&Ms, SPRS/eMASS reporting.
Why Organizations Use It
- Mandatory for DoD contract eligibility and flow-down.
- Mitigates supply chain risks, reduces breach costs.
- Provides competitive bidding advantage, builds stakeholder trust.
- Enhances operational resilience beyond compliance.
Implementation Overview
- **Phased approachGovernance, scoping/gaps, remediation, assessment, sustainment.
- Targets DIB primes/subcontractors; enclaves for segmentation.
- High complexity/cost ($100K+ SMEs); 12-18 months typical; triennial recertification.
ISO 27701 Details
What It Is
ISO/IEC 27701:2025 is the international standard for establishing, implementing, maintaining, and improving a Privacy Information Management System (PIMS). It extends ISO/IEC 27001 with privacy-specific requirements for PII controllers and processors, using a risk-based, PDCA management system approach to manage privacy risks.
Key Components
- Clauses 4–10 for management system (context, leadership, planning, operation, evaluation, improvement)
- Annex A (controller controls: lawful basis, DSARs, retention) and Annex B (processor controls: contracts, subprocessors)
- Mappings to GDPR (Annex D), ISO 27002; 100+ privacy controls
- Certification via accredited bodies, 3-year cycle with surveillance audits
Why Organizations Use It
- Demonstrates accountability for GDPR/POPIA/LGPD compliance
- Reduces privacy risks, enhances supply-chain trust
- Provides audit-ready evidence, competitive differentiation
- Builds stakeholder confidence through integrated security-privacy governance
Implementation Overview
- Phased: scope/gap analysis, controls design, operation, audits
- Suits all sizes/industries processing PII; integrates with ISMS
- Involves RoPA, DPIAs, training, vendor management; 6–18 months typical
Key Differences
| Aspect | CMMC | ISO 27701 |
|---|---|---|
| Scope | Cybersecurity for FCI/CUI in DoD supply chain | Privacy management for PII controllers/processors |
| Industry | Defense Industrial Base contractors/subcontractors | Any sector handling PII globally |
| Nature | Mandatory DoD certification program | Voluntary international privacy standard |
| Testing | Self/C3PAO/DIBCAC assessments every 3 years | Third-party certification audits, 3-year cycle |
| Penalties | Contract ineligibility, debarment | No legal penalties, loss of certification |
