NIST SP 800-171 Rev 3 covers 48.1% of NIST Cybersecurity Framework 2.0
51 of the 106 controls in NIST Cybersecurity Framework 2.0 are already satisfied by evidence you collected for NIST SP 800-171 Rev 3. 55 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 NIST Cybersecurity Framework 2.0 your NIST SP 800-171 Rev 3 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.
134 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.
System monitoring to detect attacks and indicators of potential attacks produces the analysed event set.
Audit record review and analysis for inappropriate or unusual activity is the analysis of adverse events.
Incident reporting to designated personnel and authorities within required timeframes carries directly.
Reporting audit review findings to designated personnel is exactly this provisioning of event information.
System monitoring with strategically deployed devices to detect attacks covers network monitoring.
Monitoring and controlling communications at external and key internal boundaries is network monitoring evidence.
Monitoring physical access to the facility and reviewing physical access logs is the same outcome.
Reviewing audit records for indicators of inappropriate or unusual user activity is the monitoring mechanism.
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.
