NIST SP 800-172 covers 32.1% of NIST Cybersecurity Framework 2.0
34 of the 106 controls in NIST Cybersecurity Framework 2.0 are already satisfied by evidence you collected for NIST SP 800-172. 72 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 800-172 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 3 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.
Advanced automation and analytics supporting analysts is exactly analysis of potentially adverse events.
Threat hunting analyses adverse activity to detect, track and disrupt threats evading controls.
A 24/7 security operations centre performs the continuous event analysis this subcategory requires.
Advanced analytics predicting and identifying risks correlates information across systems and components.
Threat indicator information from external organizations directly informs intrusion detection analysis.
Threat intelligence from open, commercial and government sources is integrated into monitoring and hunting analysis.
Ongoing monitoring with advanced detection capabilities covers networks and network services.
Threat hunting searches organizational systems for indicators of compromise across the network.
Claims that did not hold
3 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.
corrected 2026-08-19: judged from a title claiming multifactor authentication, while the control carried 3.5.2e password-management text. Issued 800-172 3.5.3e is comply-to-connect: prohibit connection of unknown or unverified components. Authentication evidence does not satisfy it.
Claimed at high confidence before it was rejected.
control identity corrected 2026-08-19: issued 3.13.1e is component diversity to limit malicious code propagation; these mappings are boundary protection and segmentation, judged against 3.1.3e's content which this control was wrongly carrying
Claimed at high confidence before it was rejected.
control identity corrected 2026-08-19: issued 3.13.2e is introducing unpredictability into operations; these mappings are least privilege and secure engineering, a subject that appears nowhere in the issued 800-172
Claimed at high confidence before it was rejected.
