NIST 800-171
U.S. framework protecting CUI in nonfederal systems
C-TPAT
Voluntary U.S. partnership for supply chain security.
Quick Verdict
NIST 800-171 mandates CUI cybersecurity for defense contractors via contracts, while C-TPAT is voluntary CBP partnership for supply chain security. Organizations adopt NIST for DoD compliance; C-TPAT for trade facilitation and reduced inspections.

NIST 800-171 Details
What It Is
NIST SP 800-171 Revision 3 is a U.S. government framework providing security requirements to protect Controlled Unclassified Information (CUI) confidentiality in nonfederal systems. Its primary scope targets federal contractors and supply chains, using a control-based approach tailored from NIST SP 800-53 Moderate baseline.
Key Components
- 17 families (e.g., Access Control, Audit, Supply Chain Risk Management) with ~98 requirements and Organization-Defined Parameters (ODPs).
- Core artifacts: System Security Plan (SSP) and Plan of Action and Milestones (POA&M).
- Assessment via SP 800-171A procedures (examine/interview/test).
- Built on FIPS 200 and SP 800-53; supports tailoring and enclaves.
Why Organizations Use It
- Contractual mandates via DFARS 252.204-7012 for DoD eligibility.
- Reduces breach risks, ensures CMMC Level 2 readiness.
- Builds stakeholder trust, competitive edge in federal procurement.
Implementation Overview
- Phased: scoping, gap analysis, controls, evidence collection.
- Applies to contractors handling CUI; audits via self or C3PAO.
- Timelines 6-36 months; focuses on enclaves for efficiency.
C-TPAT Details
What It Is
C-TPAT (Customs-Trade Partnership Against Terrorism) is a voluntary public-private partnership program administered by U.S. Customs and Border Protection (CBP). It focuses on securing international supply chains from terrorism and criminal threats through risk-based security measures. The approach emphasizes partnership, with members committing to Minimum Security Criteria (MSC) tailored by entity type (importers, carriers, etc.).
Key Components
- 12 core MSC domains: risk assessment, business partners, physical access, personnel security, conveyance security, IT/cybersecurity, training, and more.
- Over 100 specific criteria across domains.
- Built on governance, evidence-based implementation, and continuous improvement.
- Compliance via annual security profiles, validations, and tiered status (Tier 1-3).
Why Organizations Use It
- Trade facilitation: reduced inspections, FAST lanes, priority processing.
- No legal mandate but de facto for high-volume importers.
- Mitigates supply chain risks, enhances resilience.
- Builds trust with partners, unlocks mutual recognition agreements.
Implementation Overview
- Phased: gap analysis, remediation, profile submission, validation.
- Involves mapping, partner vetting, controls, training.
- Scalable for SMEs to globals; CBP validations required.
- 6-12 months typical, ongoing maintenance.
Key Differences
| Aspect | NIST 800-171 | C-TPAT |
|---|---|---|
| Scope | CUI cybersecurity in nonfederal systems | Physical supply chain security and trade facilitation |
| Industry | Defense contractors, federal supply chains | Importers, exporters, carriers, logistics providers |
| Nature | Mandatory via DFARS contracts, NIST baseline | Voluntary CBP partnership program |
