What are the key differences between ISO 27018 and MARS-E?

ISO 27018 has 45 controls across its framework, while MARS-E covers 8 controls. Direct mapping analysis identifies 8 overlapping controls (18% coverage). The frameworks diverge most significantly in PII Principles, where 9 ISO 27018 controls have no direct MARS-E equivalent.

How many controls map between ISO 27018 and MARS-E?

Of 45 total ISO 27018 controls, 8 map directly to MARS-E controls — representing 18% coverage. The remaining 37 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.

What are the compliance gaps when mapping ISO 27018 to MARS-E?

37 ISO 27018 controls have no direct equivalent in MARS-E. The highest concentration of gaps is in PII Principles with 9 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 and MARS-E?

The domain with the highest gap count is PII Principles (9 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
