Coverage crosswalk

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.

Every claim shows its reasoning so you can check it. Ask and a practitioner will review this pair.

A sample of what the report says

Evidenced: 03.01.01 Account Management

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.

Gap: 03.01.03 Information Flow Enforcement

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.

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.
