NIST SP 800-53 Rev 5 vs ISO 27001:2022
What is the difference between NIST SP 800-53 Rev 5 and ISO 27001:2022?
NIST 800-53 provides over 1,000 granular security and privacy controls used by US federal agencies. ISO 27001 Annex A has 93 controls. NIST is more prescriptive; ISO is more flexible and internationally recognised.
Measured coverage between these frameworks
We map controls between these two frameworks in a knowledge graph and have a person review every mapping before it is published. Below is what that review found. The figures are read live from the graph, not written by hand.
ISO 27001:2022 into NIST SP 800-53 Rev 5
54.3%163 of 300 NIST SP 800-53 Rev 5 controls carry evidence from ISO 27001:2022, leaving 137 to satisfy separately.
536 candidate mappings were examined and 342 were rejected on review, signed off 2026-08-19.
