NIST SP 800-161 Rev 1 covers 62.9% of NIST SP 800-172
22 of the 35 controls in NIST SP 800-172 are already satisfied by evidence you collected for NIST SP 800-161 Rev 1. 13 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 SP 800-172 your NIST SP 800-161 Rev 1 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.
77 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.
Risk assessment across enterprise, mission and system levels, kept current and informing decisions.
Maintains threat actor awareness and feeds it into architecture, monitoring and response decisions.
Hunts for adversary activity that evaded controls rather than waiting for an alert.
Risk responses and determinations are recorded with rationale and an accountable owner.
The security plan records the controls selected and the dependencies they address.
Continuous monitoring re-tests effectiveness on schedule and on new risk information.
Assesses whether controls actually operate rather than accepting a claim they exist.
Establishes the processes that identify and address supply chain risk for the system.
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.
The full report
Everything above is a sample. The report is every evidenced control and every gap, with the reasoning and the source document behind each one, in a form you can hand to an assessor. $299, emailed immediately.
