What are the key differences between ISO/SAE 21434 and NIST SP 1800-32?

ISO/SAE 21434 has 50 controls across its framework, while NIST SP 1800-32 covers 44 controls. Direct mapping analysis identifies 7 overlapping controls (14% coverage). The frameworks diverge most significantly in TARA, where 5 ISO/SAE 21434 controls have no direct NIST SP 1800-32 equivalent.

How many controls map between ISO/SAE 21434 and NIST SP 1800-32?

Of 50 total ISO/SAE 21434 controls, 7 map directly to NIST SP 1800-32 controls — representing 14% coverage. The remaining 43 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 1800-32?

43 ISO/SAE 21434 controls have no direct equivalent in NIST SP 1800-32. 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 1800-32?

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.
