NIST 800-171 Assessment Services
For organizations handling Controlled Unclassified Information (CUI) in partnership with the U.S. Department of Defense or other federal agencies, NIST Special Publication (SP) 800-171 is the essential compliance framework. Achieving and maintaining compliance with NIST SP 800-171 controls and requirements is often a prerequisite for eligibility in government contracts.
Aligning with this framework not only helps contractors avoid disqualification but also strengthens overall cybersecurity resilience. With increasing focus on supply chain security, compliance with NIST SP 800-171 is becoming a powerful differentiator for companies pursuing federal and state opportunities.
360 Advanced is uniquely positioned to help. As an accredited FedRAMP® Third-party Assessment Organization (3PAO) with deep experience across NIST standards, we provide the strategic guidance and practical assessments organizations need to win and retain government contracts. Our approach emphasizes both compliance and long-term security maturity, giving you confidence in every engagement.

NIST SP 800-171 (Revision 2) establishes 110 security requirements organized into 14 control families, such as Access Control, Incident Response, Configuration Management, and System Integrity. It was developed to ensure that non-federal organizations handling CUI safeguard that information at the same level of rigor expected within government systems.
The standard aligns with NIST SP 800-53, drawing from its control catalog while tailoring requirements for non-federal environments. Compliance with NIST SP 800-171 is also a foundational step toward meeting Cybersecurity Maturity Model Certification (CMMC) [LINK to CMMC page] obligations for defense contractors.
