The UK Cyber Essentials to NIST SP 800-171 Rev 3 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-171 Rev 3 controls your existing UK Cyber Essentials work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.
Coverage does not run both ways. UK Cyber Essentials into NIST SP 800-171 Rev 3 lands at 20.6%, while NIST SP 800-171 Rev 3 into UK Cyber Essentials lands at 75%, on the same two control sets. That is not a rounding difference. It is the whole reason these are two separate reports: one asks what your UK Cyber Essentials evidence buys you for NIST SP 800-171 Rev 3, the other asks the reverse.
20 of 97 NIST SP 800-171 Rev 3 controls are evidenced by work you have already done for UK Cyber Essentials. 77 are genuine gaps.
A sample of what the report says
Both require a documented approval process before an account is established.
Grounded in CE-AC.1 User Account Approval Process. Confidence high, survived the refutation pass.
Enforce approved authorizations for controlling the flow of CUI within the system and between connected systems.
Every one of the 20 evidenced controls and 77 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
27 of 36 UK Cyber Essentials controls are evidenced by work you have already done for NIST SP 800-171 Rev 3. 9 are genuine gaps.
A sample of what the report says
Account management defines establishment, membership conditions and authorisation before access.
Grounded in 03.01.01 Account Management. Confidence high, survived the refutation pass.
Where identity is established without a password, use a recognised passwordless method such as a FIDO2 authenticator or passkey, biometric, hardware security key or token, push notification or one-time code, and manage it as the...
Every one of the 27 evidenced controls and 9 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
- 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 100% in the header counts how many UK Cyber Essentials controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many NIST SP 800-171 Rev 3 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.
