Protect Controlled Unclassified Information and satisfy federal contract requirements. Expert NIST 800-171 gap assessments, SSP development, and CMMC readiness for Texas defense contractors.
NIST Special Publication 800-171 defines 110 security requirements across 14 control families that non-federal organizations must implement to protect Controlled Unclassified Information (CUI) — sensitive government data that lives outside federal systems.
If your business holds a DoD contract with a DFARS clause 252.204-7012, NIST 800-171 compliance is legally required. Non-compliance can result in contract termination, False Claims Act liability, and disqualification from future federal work.
NIST 800-171 is also the direct foundation for CMMC Level 2 — making it the essential first step for any Texas defense contractor pursuing CMMC certification.
Required documentation describing how each of the 110 controls is implemented across your environment.
Documented roadmap for any controls not yet fully implemented, with realistic timelines and milestones.
Required scoring of your implementation using the NIST 800-171A assessment methodology.
Compliance must cover all systems touching CUI — including cloud services, remote work, and mobile devices.
Every NIST SP 800-171 requirement maps to one of these 14 control families. Segler.Net assesses and implements all of them.
Limit system access to authorized users, processes, and devices. Control the flow of CUI within your organization.
Ensure personnel are aware of security risks and trained to carry out their assigned security responsibilities.
Create and retain system audit logs to enable monitoring, analysis, investigation, and reporting of unlawful activity.
Establish and maintain baseline configurations and inventories of organizational systems.
Identify system users, processes, and devices and authenticate their identities before allowing access.
Establish an operational incident-handling capability including preparation, detection, analysis, containment, and recovery.
Perform maintenance on organizational systems and provide controls on the tools and personnel performing maintenance.
Protect system media containing CUI, both paper and digital, and limit access to authorized users.
Screen individuals prior to authorizing access to systems and ensure CUI is protected during and after personnel actions.
Limit physical access to organizational systems to authorized individuals and protect systems from physical damage.
Periodically assess the risk to operations, assets, and individuals resulting from system operation and CUI processing.
Periodically assess security controls, develop and implement plans of action, and monitor security controls on an ongoing basis.
Monitor, control, and protect communications at external boundaries and key internal boundaries of systems.
Identify, report, and correct system flaws; protect from malicious code; and monitor alerts and advisories.
A proven, systematic approach to achieving and maintaining NIST 800-171 compliance for Texas federal contractors.
Evaluate all 110 NIST 800-171 requirements against your current environment and score your baseline.
Build your System Security Plan documenting CUI boundaries, system components, and control implementations.
Document all gaps with realistic remediation timelines and prioritized action items.
Implement technical controls, policies, and procedures to close identified gaps systematically.
Continuous monitoring, annual assessments, and SSP maintenance to sustain compliance.
CMMC Level 2 certification — required for DoD contracts involving CUI — maps directly to all 110 NIST SP 800-171 requirements. Achieving NIST 800-171 compliance puts you on the direct path to CMMC Level 2 certification.
