NIST 800-171 Compliance Software

Run NIST 800-171 self-assessments, collect evidence, and produce SPRS scores and POA&Ms with Isora GRC.

Define system boundaries for FCI and CUI, conduct NIST 800-171 self-assessments across every requirement, link evidence to each response, route findings into POA&Ms, and produce an SPRS score plus assessment documentation from that record, with Isora GRC, the GRC Assessment Platform™ for federal contractors.

Problem

NIST 800-171 requires documented evidence for 100+ security controls.

NIST SP 800-171 defines 110 security requirements across 14 control families for protecting CUI in nonfederal systems. Yet, many defense contractors, federal subcontractors, and universities with DoD research programs still divide that work among the DoD Assessment Methodology workbook, a separate POA&M, and shared evidence files — an approach that leaves them without the ability to connect an SPRS score to the responses and evidence supporting it.

Failure to affirm annually can lapse CMMC status, inaccurate attestations can create False Claims Act exposure, SPRS scores can filter contractors out of award consideration, and DIBCAC may even conduct government-led assessments as a result.

Solution

One platform for the NIST 800-171 self-assessment lifecycle.

Isora GRC structures the NIST 800-171 workflow into one connected workspace: self-assessments map to Rev 2 and Rev 3 requirements and control families, CUI system inventories, POA&M remediation, and SPRS scores. Responses, evidence, findings, and affected systems stay connected from assessment through remediation, giving annual CMMC Level 1 and Level 2 affirmations a traceable record behind them.

Self-Assessment

Run NIST 800-171 self-assessments for Rev 2 or Rev 3.

Launch a self-assessment across NIST 800-171 Rev 2 or Rev 3 security controls and assign each requirement to the person responsible for it. Attach documentation to each response to capture evidence and prove implementation status for every security control across revisions.

CUI Inventory

Maintain a connected inventory of every system within 800-171 scope.

Define the CUI boundary with an inventory of every system and application that stores, processes, or transmits federally classified information (FCI). View data classification, assessment results, and risks for each record to see exactly where CUI resides and which systems the self-assessment should cover.

POA&M

Manage NIST 800-171 findings through POA&M closeout.

Publish assessment findings to the risk register as POA&M items that retain their NIST 800-171 requirement, affected CUI system, evidence, and milestone dates. Track remediation against the 180-day closeout window for CMMC Level 2 with SPRS scoring impact that updates as items are closed.

Documentation

Produce the evidence package for self-assessments, affirmations, and SPRS scores.

Export documentation behind self-assessments, annual affirmations, and SPRS scores from the assessment record. Trace every result to its responses, evidence, and remediation history in an append-only audit log. Use the same package to answer DIBCAC assessments and prime contractor flow-down requests.
