CMMC vs ISO 28000
CMMC
DoD certification model verifying DIB cybersecurity maturity levels
ISO 28000
International standard for supply chain security management systems.
Quick Verdict
CMMC mandates cybersecurity certification for DoD contractors protecting FCI/CUI via NIST controls and assessments, ensuring contract eligibility. ISO 28000 provides voluntary supply chain security management for resilient operations across industries, reducing risks and enhancing trust.

CMMC Details
What It Is
Cybersecurity Maturity Model Certification (CMMC) 2.0 is a U.S. Department of Defense (DoD) certification framework verifying cybersecurity protections for Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) in the Defense Industrial Base (DIB). It uses a tiered, risk-based model with three cumulative levels: Level 1 (basic FCI safeguards), Level 2 (advanced CUI protection), and Level 3 (APT defenses).
Key Components
- Organized into 14 domains (e.g., Access Control, Incident Response) with 17 practices (Level 1), 110 from NIST SP 800-171 Rev 2 (Level 2), plus 24 from NIST SP 800-172 (Level 3).
- Built on FAR 52.204-21 basics; certification via self-assessments (Levels 1/2), C3PAO (Level 2), or DIBCAC (Level 3), reported to SPRS/eMASS.
- Features limited POA&Ms with 180-day closures.
Why Organizations Use It
Mandated for DoD contract eligibility, it mitigates supply chain risks, reduces breach costs, and provides competitive procurement advantages. Enhances operational resilience, stakeholder trust, and market access for primes/subcontractors.
Implementation Overview
Phased approach: governance, scoping/gap analysis, remediation, assessment preparation, certification, sustainment. Targets all DIB contractors/subcontractors; requires SSP, evidence collection, annual affirmations; 3-year validity. (178 words)
ISO 28000 Details
What It Is
ISO 28000:2022 is an international certification standard specifying requirements for a security management system (SMS) focused on supply chain security and resilience. It provides a risk-based framework for identifying, assessing, and treating security risks across supply chains, using a PDCA cycle.
Key Components
- Clauses 4-10 cover context, leadership, planning, support, operation, evaluation, and improvement.
- Emphasizes risk assessment, operational controls, incident response, and supplier governance.
- Aligns with ISO High Level Structure for integration with ISO 9001, 22301, 27001.
- Optional certification via accredited bodies per ISO 28003.
Why Organizations Use It
- Mitigates theft, sabotage, disruptions; reduces insurance costs.
- Meets contractual, regulatory drivers like C-TPAT equivalents.
- Enhances trade facilitation, market access, reputation.
- Builds stakeholder trust through auditable resilience.
Implementation Overview
- Phased: scoping, gap analysis, risk treatment, deployment, audits.
- Scalable for SMEs to multinationals in logistics, manufacturing.
- Global applicability; certification involves Stage 1/2 audits, surveillance.
