NIST 800-171 Compliance

Protecting Controlled Unclassified Information in Nonfederal Systems

The underlying technical requirement for protecting non-federal systems handling CUI — 110 security controls across 14 families.

"110 Controls, Continuously Monitored, Always Audit-Ready"

What Is NIST 800-171?

NIST SP 800-171 defines the security requirements for protecting Controlled Unclassified Information (CUI) in non-federal information systems. It covers 110 controls across 14 families, and it’s not optional: it’s a contractual requirement written into most DoD contracts through DFARS clause 252.204-7012. If you handle CUI and don’t comply, you risk losing your contracts.

NIST 800-171 is the technical backbone of CMMC Level 2. Achieving 800-171 compliance positions you for CMMC certification using the same evidence base: one implementation program, two regulatory outcomes.

Value Proposition: Why Choose AdVran for NIST 800-171?

NIST 800-171 is the technical backbone of CMMC and a contractual requirement for every organization handling Controlled Unclassified Information (CUI). Falling short on even a handful of controls can disqualify you from DoD contracts.

1. Full Control Family Coverage

We address all 14 control families: Access Control, Awareness and Training, Audit and Accountability, Configuration Management, Identification and Authentication, Incident Response, Maintenance, Media Protection, Personnel Security, Physical Protection, Risk Assessment, Security Assessment, System and Communications Protection, and System and Information Integrity. No gaps.

2. Automated Evidence Collection

Our GRC platform continuously collects evidence for each of the 110 controls: login records, configuration snapshots, vulnerability scan results, training completion records. Your System Security Plan (SSP) reflects reality, not aspirations.

3. POA&M Management

When gaps exist, we keep Plans of Action and Milestones (POA&M) with clear timelines, owners, and remediation steps. Auditors see a managed, transparent process rather than undocumented deficiencies.

4. Continuous Monitoring Beyond Point-in-Time

NIST 800-171 compliance isn’t a once-a-year exercise. We continuously monitor control effectiveness, catch drift, and remediate before gaps turn into audit findings or security incidents.

5. CMMC Alignment Built In

Because CMMC Level 2 maps directly to NIST 800-171, achieving 800-171 compliance with us simultaneously prepares you for CMMC certification.

Frequently Asked Questions About NIST 800-171 Compliance

Who must comply with this regulation?

This regulation applies to defense contractors, aerospace manufacturers, and technology suppliers in the US defense industrial base. Southern California’s aerospace and defense sector, centered around major primes in Long Beach, El Segundo, Anaheim, Pasadena, and Thousand Oaks, includes hundreds of companies in the DoD supply chain subject to this framework.

How does this regulation interact with CMMC requirements?

Defense contractors often need to satisfy multiple overlapping frameworks, including CMMC, DFARS, ITAR, and NIST 800-171, at the same time. Our multi-framework compliance approach addresses these requirements in one integrated program, with shared controls, documentation, and evidence collection across all applicable frameworks.

What security controls does this framework require?

Requirements include access controls for sensitive defense data, encryption, audit logging, incident response, vulnerability management, and supply chain risk management. These align closely with CMMC Level 2 controls, so organizations already working toward CMMC certification have significant ground already covered.

What are the export control implications for defense contractors?

Defense contractors handling ITAR-controlled technical data or CMMC-covered CUI must make sure that only US persons access restricted information and that foreign nationals are excluded from CUI environments. Our support team is entirely US-based, and our cloud architectures use FedRAMP-authorized environments to confirm data sovereignty.

How does AdVran support Southern California defense contractors?

We have specific experience supporting defense contractors in Southern California’s aerospace and defense corridor. We set up and manage the security controls required by defense-focused frameworks, keep compliance documentation aligned to government auditor expectations, and give clients 24/7 SOC monitoring tuned to the threat actors that specifically target the defense industrial base.
