NIST 800-53 Compliance Services
NIST SP 800-53 Rev. 5 is the most comprehensive security control catalog in the world, with 1,000+ controls across 20 families. PTG helps organizations select, implement, and assess controls for FedRAMP, FISMA, and enterprise security programs.
The Master Security Catalog
Risk-based control selection across Low, Moderate, and High impact baselines tailored to your organization.
What 800-53 Provides
- 1,000+ security and privacy controls across 20 families including new Supply Chain (SR) and PII Processing (PT)
- Three impact baselines (Low, Moderate, High) selected via FIPS 199 categorization
- Foundation for FedRAMP, FISMA, and virtually every U.S. federal security framework
Cross-Framework Mapping
- Maps to NIST 800-171, HIPAA, SOC 2, ISO 27001, and PCI DSS
- 40-60% reduction in total compliance effort by using 800-53 as your foundational framework
- Rev 5 outcome-based language makes controls applicable to any system type

Frequently Asked Questions
What is the difference between 800-53 and 800-171?
800-53 is the master catalog with 1,000+ controls for federal systems. 800-171 is a tailored subset of 110 requirements derived from the 800-53 Moderate baseline, designed for non-federal organizations handling CUI. See our detailed comparison guide.
What changed in Revision 5?
Rev 5 added Supply Chain Risk Management (SR) and PII Processing (PT) control families, consolidated security and privacy controls, and introduced outcome-based language applicable to any system type.
How does 800-53 support FedRAMP?
FedRAMP requires 800-53 controls at specific baselines for cloud service providers seeking federal authorization. PTG guides CSPs through the complete FedRAMP authorization process from readiness assessment through 3PAO engagement.
Can 800-53 satisfy multiple compliance frameworks?
Yes. 800-53 maps to virtually every major framework including HIPAA, SOC 2, ISO 27001, PCI DSS, and NIST CSF 2.0. Using 800-53 as your foundation typically reduces total compliance effort by 40-60%.
How many controls do I need to implement?
It depends on your system's FIPS 199 categorization. Low-impact systems require fewer controls than High-impact systems. PTG ensures you implement exactly the controls your risk profile requires, avoiding both over-engineering and dangerous gaps.
