ISO 27799:2025vsMARS-E
See exactly how ISO 27799:2025 controls map to MARS-E. Pre-computed mappings, identified gaps, and coverage analysis.
Need this as a report you can hand to an assessor? A coverage crosswalk for this pair can be built to order.
According to the TheArtOfService Compliance Knowledge Graph:
ISO 27799:2025 maps to MARS-E with 10% coverage across 12 directly mapped controls. Analysis of 119 ISO 27799:2025 controls identifies 118 compliance gaps, primarily concentrated in Superseded batch representation – ISO 27799:2025.

A ISO 27799:2025 to MARS-E crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which MARS-E controls your existing ISO 27799:2025 work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.
This direction has not been through crosswalk review and sign off, so no coverage figure is published for it. Reporting an unreviewed number would be worse than reporting none. It can be built to order at the same price as a pair that is already on the shelf.
If the two frameworks turn out to have too little in common for a crosswalk to help you, we say so and refund it rather than send a number worth nothing.

- Every evidenced control, with the reasoning behind it
- Every gap, with what it requires
- Its level of review stated plainly, not a bare number
Why this page shows two different percentages. The 10% in the header counts how many ISO 27799:2025 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many MARS-E controls are actually evidenced, after a pass that argued against each mapping and kept only what survived. They answer different questions and they are not meant to agree.
A crosswalk narrows the work. It does not replace an audit, and your assessor may take a different view on individual controls. Mappings between frameworks are judgements, not text printed in either standard, which is why every claim in the report shows its reasoning. Questions go to support@theartofservice.com.

What are the key differences between ISO 27799:2025 and MARS-E?
ISO 27799:2025 has 119 controls across its framework, while MARS-E covers 8 controls. Direct mapping analysis identifies 12 overlapping controls (10% coverage). The frameworks diverge most significantly in Superseded batch representation – ISO 27799:2025, where 34 ISO 27799:2025 controls have no direct MARS-E equivalent.
How many controls map between ISO 27799:2025 and MARS-E?
Of 119 total ISO 27799:2025 controls, 12 map directly to MARS-E controls, representing 10% coverage. The remaining 118 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping ISO 27799:2025 to MARS-E?
118 ISO 27799:2025 controls have no direct equivalent in MARS-E. The highest concentration of gaps is in Superseded batch representation – ISO 27799:2025 with 34 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 27799:2025 and MARS-E?
The domain with the highest gap count is Superseded batch representation – ISO 27799:2025 (34 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
