PCI DSS
Global standard securing payment cardholder data environments
CMMC
DoD certification verifying cybersecurity maturity for DIB contractors
Quick Verdict
PCI DSS secures cardholder data for global payment processors via contractual audits, while CMMC certifies DoD contractors for FCI/CUI protection through tiered NIST assessments. Organizations adopt PCI DSS to avoid fines and retain processing rights; CMMC ensures contract eligibility and supply chain security.
PCI DSS
Payment Card Industry Data Security Standard (PCI DSS)
Key Features
- 12 requirements across 6 objectives protect CHD/SAD
- Contractual enforcement with fines and processing bans
- Multi-level validation via SAQ/ROC for Levels 1-4
- Scope reduction through segmentation and tokenization
- v4.0 customized/defined approaches with MFA emphasis
CMMC
Cybersecurity Maturity Model Certification (CMMC)
Key Features
- Three cumulative maturity levels aligned to data sensitivity
- 110 NIST SP 800-171 controls verified at Level 2
- C3PAO and DIBCAC third-party/government assessments
- Enclave scoping for targeted enterprise compliance
- POA&Ms limited to 180-day closures

PCI DSS Details
What It Is
PCI DSS (Payment Card Industry Data Security Standard) is a contractual security framework managed by the PCI Security Standards Council. It mandates technical and operational controls to protect cardholder data (CHD) and sensitive authentication data (SAD) for merchants and service providers handling payment cards. Its control-based approach focuses on the cardholder data environment (CDE) via risk-mitigating requirements.
Key Components
- 12 core requirements grouped into 6 control objectives (e.g., secure networks, vulnerability management, access controls).
- Over 300 sub-requirements with testing procedures.
- Compliance levels (1-4 for merchants, 2 for providers) using SAQ, ROC, ASV scans.
- v4.0 supports defined/customized implementation approaches.
Why Organizations Use It
- Contractual obligation from card brands to avoid fines, bans.
- Reduces breach risks/costs ($37/record avg.), builds trust.
- Enhances security hygiene, supports GDPR alignment.
Implementation Overview
Phased Assess-Repair-Report cycle: scope CDE, gap analysis, remediate (segmentation, MFA), validate annually. Applies globally to card-handling entities; QSA audits for high-volume.
CMMC Details
What It Is
The Cybersecurity Maturity Model Certification (CMMC) is a U.S. Department of Defense (DoD) certification framework ensuring cybersecurity protections for Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) across the Defense Industrial Base (DIB). It employs a tiered, control-based model with three maturity levels, drawing from NIST standards for verifiable compliance.
Key Components
- **Three cumulative levelsLevel 1 (17 FAR 52.204-21 practices), Level 2 (110 NIST SP 800-171 Rev 2 practices), Level 3 (+24 NIST SP 800-172 enhancements)
- 14 domains (e.g., Access Control, Incident Response, Risk Assessment)
- Built on FAR, NIST SP 800-171/172; requires System Security Plan (SSP) and evidence
- Assessment paths: self-assessment, C3PAO, or DIBCAC, valid 3 years with annual affirmations
Why Organizations Use It
- Mandatory for DoD contract eligibility, avoiding disqualification and penalties
- Mitigates supply chain risks, reduces breach costs, enhances resilience
- Provides procurement advantage, builds prime/sub trust
Implementation Overview
Phased: scoping/gap analysis, remediation/POA&M, implementation, assessment prep/certification, sustainment. Applies to all DIB contractors/subcontractors; complex scoping via enclaves recommended.

| Aspect | PCI DSS | CMMC |
|---|---|---|
| Scope | Cardholder data protection (CHD/SAD) | FCI/CUI protection across 14 domains |
| Industry | Payment card merchants/service providers, global | DoD contractors/subcontractors, US DIB |
| Nature | Contractual standard, enforced by card brands | Certification program, DoD contract requirement |
| Testing | Quarterly ASV scans, annual ROC/SAQ by QSA | Annual self-assess or triennial C3PAO/DIBCAC |
| Penalties | Fines, processing privilege loss | Contract ineligibility, no direct fines |
