Meet NIST 800-171 with confidence
If you handle Controlled Unclassified Information (CUI) under a U.S. federal contract, compliance isn’t optional. Vanta automates the work to meet NIST 800-171 requirements, so you can protect CUI and reduce risk with less manual effort.

Automate and continuously monitor NIST 800-171
Vanta connects to your cloud, identity, device, and code tools to collect evidence automatically. Instead of managing everything in spreadsheets, you get continuous monitoring, alerts for control drift, and a live progress view.
Automated tests that monitor controls hourly, so you stay compliant every day—not just at audit time.
Integrations with your cloud, code, identity, and device tools for a complete, automated view of compliance.
Know exactly what’s required and how to prove it
NIST 800-171 can be complex. Vanta makes it manageable by breaking down each control into clear steps, mapped to policies, tests, and documents from our GRC experts, so you know what to implement and what to share.
Scope NIST 800-171 to your real environment
Not every system or user handles CUI, and your compliance program should reflect that. Vanta helps you define scope, include only in-scope assets, exclude the rest, and keep your NIST 800-171 program focused and defensible.
Work once, scale across many
Reuse work across CMMC 2.0, ISO 27001, HIPAA, and more. See how much of each framework you’ve already covered so you can plan what’s next and move faster.

FAQ
NIST 800-171 defines how to protect Controlled Unclassified Information (CUI) in nonfederal systems. If you contract with U.S. federal agencies and handle CUI, you likely need to comply—especially across the Defense Industrial Base and subcontractors.
Vanta maps requirements to controls, automates evidence collection across your tech stack, and gives you a live view of compliance. You’ll be ready for assessments and requests, with required CUI protections implemented and monitored in one place.
Yes. Vanta cross-maps controls so you can reuse work across frameworks. Since NIST 800-171 is derived from 800-53 and underpins CMMC Level 2, there is opportunity for high overlap.
CUI includes sensitive, unclassified info like technical data, contract details, or vulnerability data. If your contract references CUI, DFARS CUI safeguarding clauses, or 800-171—or if you get data marked “CUI”—you’re handling it. Scope systems, users, and vendors accordingly.
800-171 is a subset of 800-53, tailored for nonfederal systems. CMMC Level 2 is based on 800-171, but adds assessment and certification. 800-53 is more comprehensive and underpins FedRAMP Moderate and High.
