UK Cyber Essentials covers 16.3% of CIS Controls v8
25 of the 153 controls in CIS Controls v8 are already satisfied by evidence you collected for UK Cyber Essentials. 128 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 CIS Controls v8 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.
54 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 anti-malware deployed on every in-scope device.
Both require anti-malware signature and engine updates to be kept current.
Both require auto-run and auto-play execution to be disabled on removable media.
On-access scanning evidence covers automatic scanning of removable media when opened.
Both require firmware and software on network infrastructure to be kept current.
Both require users trained on password quality, uniqueness and credential handling.
Both require out-of-support software to be removed or segregated.
Both require software in use to be vendor supported and receiving security updates.
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.
