ISO 27701:2019 vs NIST SP 800-53 Rev 5

What is the difference between ISO 27701:2019 and NIST SP 800-53 Rev 5?

ISO 27701:2019 is a information security framework applying in International, with 136 controls across 6 domains. NIST SP 800-53 Rev 5 is a information security framework applying in the United States, with 192 controls across 24 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.

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 27701:2019 into NIST SP 800-53 Rev 5

3.7%

11 of 300 NIST SP 800-53 Rev 5 controls carry evidence from ISO 27701:2019, leaving 289 to satisfy separately.

401 candidate mappings were examined and 344 were rejected on review, signed off 2026-08-19.

ISO 27701:2019 has 136 controls while NIST SP 800-53 Rev 5 has 192 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 ISO 27701:2019 and NIST SP 800-53 Rev 5?

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 ISO 27701:2019 and NIST SP 800-53 Rev 5 so you can identify shared requirements and avoid duplicate effort.

How do ISO 27701:2019 and NIST SP 800-53 Rev 5 controls map to each other?

Our platform maps controls between ISO 27701:2019 and NIST SP 800-53 Rev 5 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, ISO 27701:2019 or NIST SP 800-53 Rev 5?

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.
