Assess the gaps
Review what’s implemented, partial, or missing against your required revision, including all 110 requirements for Revision 2. Get a prioritized remediation plan.
NIST 
800-171 compliance.No shortcuts.
Prepare for NIST 800-171 with hands-on security implementation, clear documentation, and automated evidence collection. We scope your program around CUI and the revision your contract requires.
Real implementation- Clear documentation
- Assessment readiness
Protect CUI. Meet contract requirements.
Start with your Controlled Unclassified Information (CUI) boundary. We confirm the NIST SP 800-171 revision and assessment route your contract requires.
CUI systems and security protection assets in scope
110 requirements across 14 families in Revision 2
Documentation backed by implementation evidence
Close the gaps.
Prepare for assessment.
Move from gap assessment to implemented controls, an accurate System Security Plan (SSP), and current evidence.
Implement security controls
Work with our team on encryption, MFA, logging, and access control configuration to close the gaps in your environment.
Document what you do
Build an SSP that reflects your actual systems and controls, with clear answers to how each requirement is implemented.
Collect evidence automatically
Connect your systems to gather screenshots, configurations, and logs continuously. Reduce the time your team spends chasing evidence.
Prepare for CMMC
Organize controls, documentation, and evidence for your contract’s assessment route. If a C3PAO assessment is required, we help you prepare.
Security first. Compliance follows.Already have SOC 2?
Already have SOC 2?
Build on it.
Map existing SOC 2 controls and evidence to your contract’s NIST 800-171 requirements. Reuse relevant work and focus on gaps within your CUI scope.

Real security.
Starts with a closer look.
We test the systems you actually run, not a questionnaire. Every check shows what’s working, what isn’t, and which frameworks each gap touches.
One gap.
More than one framework.
Every result maps to the frameworks it belongs to. One gap can hold back several at once.
Your agent fixes what it can.
It prepares the fix, you approve it, and we retest. One verified fix counts toward every framework that needs it.
An expert handles the rest.
Some gaps need human judgment. Your Oneleet expert works through the details with you and verifies the result.
One fix. Progress everywhere.
The same security work moves SOC 2, ISO 27001, GDPR, HIPAA, FedRAMP and ISO 42001 forward together. Explore the checks they share.
NIST 800-171 questions,
answered plainly.
Scope, assessment, and what you can reuse from your existing security work.
How long does this actually take?
Timing depends on your existing security, remediation work, and CUI scope. We assess your starting point before building a realistic plan.
Do I need to apply this to my whole platform?
Not necessarily. Scope includes systems processing, storing, or transmitting CUI and those providing security protection. We define the boundary from your environment and applicable assessment requirements.
What’s the difference between NIST 800-171 and CMMC?
NIST SP 800-171 defines security requirements for CUI. CMMC Level 2 assesses Revision 2’s 110 requirements, through self-assessment or C3PAO assessment depending on your contract.
Can I use my SOC 2 work?
Yes. We map existing controls and evidence to NIST 800-171 and identify gaps. What carries over depends on your implementation and CUI scope.
What if I have gaps I can’t close immediately?
A Plan of Action and Milestones (POA&M) records gaps, fixes, and deadlines. CMMC permits only eligible gaps, with strict scoring and closeout rules. A plan alone does not make you compliant.
Do you do the CMMC assessment?
No. CMMC Third-Party Assessment Organizations (C3PAOs) conduct third-party assessments. We help you prepare and support you through the process.
