Framework Defense, Supply Chain & NIST Catalogue
NIST SP 800-53
NIST Special Publication 800-53 Revision 5, "Security and Privacy Controls for Information Systems and Organizations", is the US federal catalog of security and privacy controls.
Revision 5 was published September 2020, with an update in December 2020 and further releases since; Release 5.2.0 of August 27, 2025 added controls on software update integrity and cyber resiliency in response to Executive Order 14306.
The catalog holds roughly 1,200 controls and enhancements across twenty families (access control, audit and accountability, configuration management, incident response, supply chain risk management, PII processing and transparency, and so on).
Baselines for low, moderate, and high impact systems and the privacy baseline are published separately in SP 800-53B, and assessment procedures in SP 800-53A. FedRAMP, DoD's Cloud SRG, StateRAMP, and many private frameworks derive their control sets from it, and NIST SP 800-171 is a tailored subset.
SP 800-53 is a catalog, not a certification, so nobody certifies "to 800-53" directly; the assessment happens inside the program that adopts a baseline.
What the catalog demands in writing is, for each selected control, a policy and procedure (every family starts with a -1 control requiring exactly that), the implementation description in the system security plan, and evidence that the control operates.
Organizations therefore end up with a full set of family-level policies, a system security plan that addresses each control, a tailoring record, and assessment evidence mapped control by control.

Who has to comply
Mandatory for US federal information systems under FISMA and OMB Circular A-130 (agencies must apply the baselines through the RMF). Cloud providers serving agencies apply it through FedRAMP; defense contractors meet a tailored subset via NIST SP 800-171 and CMMC.
Private organizations adopt it voluntarily, often because a customer or regulator names it as an acceptable control set.
What the assessor asks to see
For each control family: the policy and procedures (-1 controls); system security plan implementation statements; configuration baselines and change records; access control lists and reviews; audit logs and monitoring evidence; vulnerability scans and remediation; incident response plan and test records; contingency plan and tests; personnel screening and training records; supply chain risk documentation; privacy notices and PII inventories; assessment reports and POA&Ms.
Release 5.2.0 (August 2025)
Release 5.2.0 introduced new controls and enhancements on software and system resiliency by design, developer testing, secure deployment and management of updates, and software integrity and validation, including SA-24 (Design for Cyber Resiliency). Programs that adopt SP 800-53 (FedRAMP, agency baselines) set their own dates for incorporating new releases.
Assessors
Who assesses NIST SP 800-53
None for the catalog itself. Within adopting programs: FedRAMP-recognized 3PAOs for cloud services, agency security control assessors for FISMA systems, DoD assessors for defense systems, and C3PAOs for the CMMC subset. Accredited by Program-specific: A2LA and other FedRAMP-recognized bodies for 3PAOs; the Cyber AB for C3PAOs; agencies designate their own assessors.

Consultants
Who helps with NIST SP 800-53
The largest control-framework consulting market in the US. Consultants map existing controls to the catalog, write the family policies and system security plan, and prepare for FedRAMP or agency assessment. GRC platforms ship it as a built-in framework.
Engagements range from a few months for a gap assessment to a year or more for a first FedRAMP authorization.
