What are the key differences between ISO/SAE 21434 and NIST Post-Quantum Cryptography Standards (FIPS 203, 204, 205)?

ISO/SAE 21434 has 50 controls across its framework, while NIST Post-Quantum Cryptography Standards (FIPS 203, 204, 205) covers 8 controls. Direct mapping analysis identifies 3 overlapping controls (6% coverage). The frameworks diverge most significantly in ISO/SAE 21434: Operations Security, where 6 ISO/SAE 21434 controls have no direct NIST Post-Quantum Cryptography Standards (FIPS 203, 204, 205) equivalent.

How many controls map between ISO/SAE 21434 and NIST Post-Quantum Cryptography Standards (FIPS 203, 204, 205)?

Of 50 total ISO/SAE 21434 controls, 3 map directly to NIST Post-Quantum Cryptography Standards (FIPS 203, 204, 205) controls — representing 6% coverage. The remaining 47 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 Post-Quantum Cryptography Standards (FIPS 203, 204, 205)?

47 ISO/SAE 21434 controls have no direct equivalent in NIST Post-Quantum Cryptography Standards (FIPS 203, 204, 205). The highest concentration of gaps is in ISO/SAE 21434: Operations Security with 6 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 Post-Quantum Cryptography Standards (FIPS 203, 204, 205)?

The domain with the highest gap count is ISO/SAE 21434: Operations Security (6 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
