NIST 800-171

NIST SP 800-171

Protecting Controlled Unclassified Information in Nonfederal Systems

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

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

NIST 800-171 is not a suggestion—it’s 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 & Training, Audit & Accountability, Configuration Management, Identification & Authentication, Incident Response, Maintenance, Media Protection, Personnel Security, Physical Protection, Risk Assessment, Security Assessment, System & Communications Protection, and System & Information Integrity. No gaps, no shortcuts.

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—so your System Security Plan (SSP) reflects reality, not aspirations.

3. POA&M Management

When gaps exist, we maintain Plans of Action & 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, detect drift, and remediate before gaps become 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 AdVran simultaneously prepares you for CMMC certification—one effort, two outcomes.
