What is NIST 800-171 Readiness?

NIST Special Publication 800-171 defines 110 security requirements across 14 control families for protecting Controlled Unclassified Information (CUI) in non-federal systems. Compliance has been mandatory for DoD contracts since 2017 via DFARS 252.204-7012. CMMC 2.0 (effective December 2024) now requires third-party assessment for most contracts involving CUI. CUI includes technical data, export-controlled information (ITAR/EAR), defense specifications, contract performance data, PII of government employees, law enforcement sensitive information, critical infrastructure data, and R&D data. Smaller contractors (under 100 employees, single site) can achieve compliance in 1-3 months. Larger organizations with multiple sites and complex IT need 3-6 months. We develop your System Security Plan (SSP) from your actual environment - not from templates. We document your SPRS score (maximum 110, minimum -203), create your POA&M with specific remediation steps, interim mitigations, responsible parties, and completion dates. Critical: Your SPRS score is visible to all DoD contracting officers. False Claims Act violations apply for inflated scores. An outdated SSP creates additional legal exposure. We ensure your documentation accurately reflects your implementation status.

For small projects and ad-hoc work outside our pre-agreed packages or retainers, our standard hourly rate is $460.

Who Needs NIST 800-171 Readiness?

Defense contractors and subcontractors handling CUI who need their first SSP and POA&M built from their actual environment

Federal government suppliers whose prime contractor is now demanding SPRS scores and compliance evidence

Organizations pursuing CMMC Level 2 certification that need all 110 controls implemented and evidenced

Companies that self-reported an SPRS score but have never validated their actual implementation status

Subcontractors who need to flow NIST 800-171 requirements down to their own supply chain

Contractors facing DFARS 252.204-7012 requirements in active or upcoming DoD solicitations

Priced on the 110 NIST 800-171 controls relative to our SOC 2 baseline. The gap assessment audits all 110 controls whatever you already hold, so its scope does not shrink. Existing ISO 27001 or SOC 2 work reduces the implementation phase, and only by the real effort those controls represent, not their count, since a small share of controls can be most of the effort. NIST 800-171 readiness also positions you for CMMC Level 2. Fixed-price proposal within 24 hours of scoping, and you review the report before any invoice.
