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 SP 800-53 Rev 5 is a information security framework applying in the United States, with 192 controls across 22 domains. ISO 27001:2022 is a information security framework applying in International, with 56 controls across 5 domains. Both govern the same subject, so their requirements overlap; the mapping below shows which controls carry across and which are asked for by only one of them.

ISO 27001:202256 controls

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.

Coverage is directional. Mapping A into B is a different measurement from B into A, because the two standards do not carry the same depth on the same subjects.

Questions people ask about NIST SP 800-53 Rev 5 and ISO 27001:2022

What is the difference between NIST SP 800-53 Rev 5 and ISO 27001:2022?

NIST SP 800-53 Rev 5 has 192 controls while ISO 27001:2022 has 56 controls. Both frameworks address compliance requirements but differ in scope, focus, and applicability. Use our platform to explore the exact control-to-control mappings.

Do I need both NIST SP 800-53 Rev 5 and ISO 27001:2022?

Whether you need both depends on your industry, regulatory requirements, and customer expectations. Many organizations implement multiple frameworks simultaneously. Our compliance platform helps you map controls between NIST SP 800-53 Rev 5 and ISO 27001:2022 so you can identify shared requirements and avoid duplicate effort.

How do NIST SP 800-53 Rev 5 and ISO 27001:2022 controls map to each other?

Our platform maps controls between NIST SP 800-53 Rev 5 and ISO 27001:2022 at a granular level. Each mapping shows whether controls are fully aligned, partially aligned, or represent gaps. This helps you prioritize implementation when pursuing both frameworks.

Which framework should I implement first, NIST SP 800-53 Rev 5 or ISO 27001:2022?

The best starting point depends on your specific regulatory requirements, industry, and customer demands. Consider which framework is most urgently required by your stakeholders or regulators. Use our free compliance platform to run a gap analysis and determine the optimal implementation sequence.
