Enhanced Security for Critical CUI Programs
When baseline NIST 800-171 protections are not enough, SP 800-172 provides enhanced security requirements designed to defend against Advanced Persistent Threats and nation-state adversaries targeting critical programs and high-value assets.
Enhanced Requirements for APT Defense
SP 800-172 assumes sophisticated adversaries will gain access and focuses on limiting their ability to achieve objectives once inside.
What 800-172 Adds
- Penetration-resistant architecture that limits lateral movement
- Zero trust implementation with continuous verification
- Dual authorization for critical operations on CUI systems
- Cyber resiliency to operate through attacks
PTG Implementation
- Purple team exercises simulating APT tactics for your industry
- Micro-segmentation preventing single-exploit compromise
- Threat hunting with MITRE ATT&CK-mapped detection
- CMMC Level 3 preparation for government-led assessments

Frequently Asked Questions
How does 800-172 differ from 800-171?
NIST 800-171 provides baseline CUI protection. SP 800-172 adds enhanced requirements for critical programs, assuming adversaries will breach the perimeter and focusing on limiting damage and maintaining operations.
Is 800-172 required for CMMC Level 3?
Yes. CMMC Level 3 will incorporate enhanced requirements derived from 800-172. Government-led assessments at this level demand demonstrable advanced control implementation.
What is penetration-resistant architecture?
Architecture designed so that an attacker gaining initial access cannot easily move laterally, escalate privileges, or exfiltrate data without triggering detection and response mechanisms.
Does PTG provide ongoing threat hunting?
Yes. PTG conducts scheduled and hypothesis-driven threat hunts targeting MITRE ATT&CK techniques relevant to your threat profile, using behavioral analytics on our private AI infrastructure.
