NIST SP 800-39 vs ISO 27005

What is the difference between NIST SP 800-39 and ISO 27005?

NIST SP 800-39 is a information security framework applying in the United States, with 8 controls across 8 domains. ISO 27005 is a information security framework applying in International, with 26 controls across 11 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.

Questions people ask about NIST SP 800-39 and ISO 27005

What is the difference between NIST SP 800-39 and ISO 27005?

NIST SP 800-39 has 8 controls while ISO 27005 has 26 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 800-39 and ISO 27005?

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 800-39 and ISO 27005 so you can identify shared requirements and avoid duplicate effort.

How do NIST SP 800-39 and ISO 27005 controls map to each other?

Our platform maps controls between NIST SP 800-39 and ISO 27005 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 800-39 or ISO 27005?

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.
