NIST SP 800-171 is the NIST publication for Protecting Controlled Unclassified Information in Nonfederal Systems.
NIST SP 800-171 covers how organizations outside the US federal government protect Controlled Unclassified Information (CUI) in their own systems.
ThreeShield's CISSP- and CISA-certified assessors run the NIST SP 800-171 engagement, and Lavawall® collects the technical evidence continuously, so your posture is current the day an auditor, insurer, or client asks for it, not just at renewal.

It likely does if your organization stores or processes Controlled Unclassified Information (CUI) on nonfederal systems, which is what NIST SP 800-171 is written to protect. We confirm scope in the first call, at no charge.
A gap assessment against NIST SP 800-171 usually takes a few weeks, depending on your starting point. Closing the gaps and standing up the evidence takes longer and is where most of the work sits. Because Lavawall® is already collecting the technical evidence while we work, you do not restart from zero at reassessment.
Yes. Many clients begin self-serve on Lavawall®, then bring in ThreeShield for the assessment, the policies, and the sign-off once they know where the gaps are. The three engagement models below are meant to be moved between.
