What are the key differences between ISO 27018:2019 and ISO/SAE 21434?

ISO 27018:2019 has 84 controls across its framework, while ISO/SAE 21434 covers 50 controls. Direct mapping analysis identifies 12 overlapping controls (14% coverage). The frameworks diverge most significantly in Access control – ISO 27018:2019, where 13 ISO 27018:2019 controls have no direct ISO/SAE 21434 equivalent.

How many controls map between ISO 27018:2019 and ISO/SAE 21434?

Of 84 total ISO 27018:2019 controls, 12 map directly to ISO/SAE 21434 controls — representing 14% coverage. The remaining 72 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.

What are the compliance gaps when mapping ISO 27018:2019 to ISO/SAE 21434?

72 ISO 27018:2019 controls have no direct equivalent in ISO/SAE 21434. The highest concentration of gaps is in Access control – ISO 27018:2019 with 13 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 27018:2019 and ISO/SAE 21434?
