NIST 800-171 Compliance Services
Federal contractors handling Controlled Unclassified Information must implement all 110 security requirements in NIST SP 800-171. PTG delivers end-to-end compliance from gap assessment to CMMC certification readiness.
Complete 110-Control Coverage
From documentation to technical implementation, PTG addresses every requirement across all 14 control families.
Technical Implementation
- CUI enclave architecture that reduces compliance scope by 60-80%
- FIPS 140-2 validated encryption for data at rest and in transit
- Multi-factor authentication, endpoint detection, and SIEM integration
- Vulnerability management with defined scanning cadences
Documentation and Assessment
- System Security Plan (SSP) with control implementation statements
- POA&M development with realistic timelines and milestones
- SPRS score calculation and optimization strategy
- CMMC-ready evidence packages for C3PAO assessment
The 110-Control Framework
NIST 800-171 organizes security requirements across 14 families mandated by DFARS 252.204-7012.
Access Control
Limit system access, enforce least privilege, control remote and wireless access, and manage session locks across CUI systems.
System and Communications Protection
Monitor system boundaries, implement encryption, establish subnetworks, and protect CUI in transit.
Identification and Authentication
Identify users and devices, implement multi-factor authentication, and manage authenticator lifecycle.
Audit, Config Management, Media
Create and protect audit records, establish configuration baselines, and sanitize media containing CUI.
System and Information Integrity
Identify and correct flaws, provide malicious code protection, and monitor security alerts in real time.
Training, IR, Maintenance, Personnel, Physical, Risk Assessment
Complete the framework with security awareness, incident handling, maintenance controls, and risk-based vulnerability management.

Frequently Asked Questions
What is the SPRS score and why does it matter?
The Supplier Performance Risk System score ranges from -203 to 110, calculated using DoD Assessment Methodology. Contracting officers use SPRS scores in source selection decisions. Scores below 110 indicate gaps that can disqualify organizations from contract awards.
How long does NIST 800-171 compliance take?
PTG's proven methodology reduces time-to-compliance from 18+ months to as few as 6 months through parallel workstreams, pre-built policy templates, and automated evidence collection.
What is the difference between 800-171 Rev 2 and Rev 3?
Revision 3 (2024) restructures requirements with updated control language and enhanced mapping to NIST 800-53. PTG prepares organizations for both current and future requirements simultaneously.
How does 800-171 relate to CMMC?
CMMC Level 2 requires implementation of all 110 NIST 800-171 requirements. Every PTG engagement is designed with CMMC certification in mind, using C3PAO evaluation methodology for documentation and evidence collection.
What is a CUI enclave?
A CUI enclave isolates CUI processing into a purpose-built environment with strict access controls, reducing compliance scope by 60-80%. Options include segmented on-premises networks or cloud solutions on Microsoft GCC High or AWS GovCloud.
Do you provide ongoing compliance support?
Yes. Our managed compliance program includes quarterly security control assessments, continuous vulnerability scanning, annual SSP updates, SPRS score maintenance, and 800-171A assessment services.
