What are the key differences between ISO/SAE 21434 and NIST SP 800-63-4?

ISO/SAE 21434 has 50 controls across its framework, while NIST SP 800-63-4 covers 8 controls. Direct mapping analysis identifies 17 overlapping controls (34% coverage). The frameworks diverge most significantly in TARA, where 5 ISO/SAE 21434 controls have no direct NIST SP 800-63-4 equivalent.

How many controls map between ISO/SAE 21434 and NIST SP 800-63-4?

Of 50 total ISO/SAE 21434 controls, 17 map directly to NIST SP 800-63-4 controls — representing 34% coverage. The remaining 33 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.

What are the compliance gaps when mapping ISO/SAE 21434 to NIST SP 800-63-4?

33 ISO/SAE 21434 controls have no direct equivalent in NIST SP 800-63-4. The highest concentration of gaps is in TARA with 5 unmapped controls. These gaps represent areas where additional controls, policies, or documentation must be created to achieve compliance with both frameworks.

Which control domains have the most gaps between ISO/SAE 21434 and NIST SP 800-63-4?

The domain with the highest gap count is TARA (5 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
