UK Cyber Essentials covers 22.7% of CMMC 2.0

25 of the 110 controls in CMMC 2.0 are already satisfied by evidence you collected for UK Cyber Essentials. 85 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 CMMC 2.0 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.

56 candidate mappings were examined and 1 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.

CE-AC.2AC.L2-3.1.1argued against and upheld
Authorized Access Control

Both require a unique authenticated account before system access is allowed.

CE-AC.1AC.L2-3.1.1argued against and upheld
Authorized Access Control

Both limit access to users authorised through a documented approval process.

CE-AC.7AC.L2-3.1.15argued against and upheld
Privileged Remote Access

Both require multi-factor authentication on administrative accounts reached remotely.

CE-FW.3AC.L2-3.1.15argued against and upheld
Privileged Remote Access

Both require remote privileged access protected by MFA or a restricted allowlist.

CE-AC.5AC.L2-3.1.2argued against and upheld
Transaction & Function Control

Both separate administrative transactions from routine user activity by account type.

CE-AC.4AC.L2-3.1.2argued against and upheld
Transaction & Function Control

Both control which functions an account is permitted to execute through privilege approval.

CE-AC.6AC.L2-3.1.5argued against and upheld
Least Privilege

Both require periodic review and downgrade of privileges no longer needed.

CE-AC.4AC.L2-3.1.5argued against and upheld
Least Privilege

Both require privileges granted only where controlled and approved as necessary.

Claims that did not hold

1 proposed mappings for this pair were rejected. They are kept in the graph rather than deleted, so what was thrown out is as inspectable as what survived. A crosswalk that never rejects anything is not being judged.

CE-AC.3IA.L2-3.5.6
Identifier Handling

re-judged once CMMC 2.0 carried real requirement text rather than a pointer: leaver-triggered account removal is not inactivity-triggered disablement

Claimed at high confidence before it was rejected.
