What are the key differences between ISO/SAE 21434 and ISO 27799?

ISO/SAE 21434 has 50 controls across its framework, while ISO 27799 covers 46 controls. Direct mapping analysis identifies 9 overlapping controls (18% coverage). The frameworks diverge most significantly in TARA, where 5 ISO/SAE 21434 controls have no direct ISO 27799 equivalent.

How many controls map between ISO/SAE 21434 and ISO 27799?

Of 50 total ISO/SAE 21434 controls, 9 map directly to ISO 27799 controls — representing 18% coverage. The remaining 41 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 ISO 27799?

41 ISO/SAE 21434 controls have no direct equivalent in ISO 27799. 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 ISO 27799?
