NIST 800-171 Readiness & CUI Safeguarding

What we assess

We identify CUI flows and the systems, people, and external providers involved. The readiness review uses the revision and assessment expectations required by the engagement or contract. System documentation, implementation evidence, and planned corrective actions must reflect the real environment, including external services and shared responsibilities.

Evidence to prepare

• CUI boundary and data-flow diagrams, system inventory, and provider responsibilities.
• System security documentation and safeguard implementation records.
• Access reviews, configuration records, monitoring activities, and evidence addressing applicable assessment objectives.

Keep design evidence separate from operating evidence. An approved procedure shows how a control is designed; dated records show whether it ran consistently over the review period. Evidence should identify its source, owner, scope, and collection date.

What you receive

• Scoped readiness findings against the applicable revision.
• System documentation and evidence organization recommendations.
• Remediation priorities and a plan for closing evidence gaps before assessment.

Common questions

Should we automatically use the latest NIST revision for CMMC?

Confirm the contract and current CMMC requirements first. Publication of a newer NIST revision does not automatically change the revision incorporated into a particular procurement or assessment requirement.

What determines the engagement timeline and cost?

The system boundary, number of entities and locations, existing control maturity, evidence availability, and assessment pathway determine the effort. Share your customer requirements and target milestone so we can define a realistic scope before proposing a schedule.
