What are the key differences between ISO 27799 and MARS-E?

ISO 27799 has 46 controls across its framework, while MARS-E covers 8 controls. Direct mapping analysis identifies 12 overlapping controls (26% coverage). The frameworks diverge most significantly in Operations, where 4 ISO 27799 controls have no direct MARS-E equivalent.

How many controls map between ISO 27799 and MARS-E?

Of 46 total ISO 27799 controls, 12 map directly to MARS-E controls — representing 26% coverage. The remaining 34 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.

What are the compliance gaps when mapping ISO 27799 to MARS-E?

34 ISO 27799 controls have no direct equivalent in MARS-E. The highest concentration of gaps is in Operations with 4 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 27799 and MARS-E?

The domain with the highest gap count is Operations (4 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
