UK Cyber Essentials covers 14% of ISO 27001:2022
13 of the 93 controls in ISO 27001:2022 are already satisfied by evidence you collected for UK Cyber Essentials. 80 are genuine gaps. Every claim below was judged against both control sets and then argued against; the ones that did not survive are published further down with the reason each failed.
This number is directional. It says how much of ISO 27001:2022 your UK Cyber Essentials evidence satisfies. The reverse pair is a different number, often very different, because a security standard has enormous depth for access control and almost none for lawful basis or data subject rights.
52 candidate mappings were examined and 0 were removed. Signed off 2026-08-19, review level machine verified. Mappings were judged by Claude Code rather than read line by line by a practitioner. Every claim shows its reasoning so you can check it. Ask and a practitioner will review this pair.
Where the gaps are
Coverage is never evenly spread. A source standard usually satisfies one part of a target almost completely and barely touches another, and which part is which is the thing worth knowing before you plan the work.
Theme level, not control level, deliberately. The per-control list of what is evidenced and what is a gap is the report itself, so publishing it here would be publishing the thing being sold.
Claims that held
A sample. Each one names the control whose evidence does the work, the control it satisfies, and why.
Both require identities removed or disabled at the end of the lifecycle.
Both require each person to hold a unique identity used to authenticate.
Both require identity creation to run through a documented approval step.
Both require a process to replace authentication information on suspected compromise.
Both require personnel guided on handling and choosing authentication information.
Both set strength requirements for the authentication information issued to users.
Both require default authentication information replaced before a system is used.
Both require access rights reviewed regularly and modified where no longer justified.
Claims that did not hold
Nothing proposed for this pair was rejected in review. That is unusual and worth knowing rather than hiding: it means the candidate set was small and every candidate held.
The full report
Everything above is a sample. The report is every evidenced control and every gap, with the reasoning and the source document behind each one, in a form you can hand to an assessor. $299, emailed immediately.
