NIST SP 800-53 Rev 5 covers 67.9% of NIST Cybersecurity Framework 2.0
72 of the 106 controls in NIST Cybersecurity Framework 2.0 are already satisfied by evidence you collected for NIST SP 800-53 Rev 5. 34 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.
What this leaves you to do
NIST Cybersecurity Framework 2.0 has 106 controls. Holding NIST SP 800-53 Rev 5 already evidences 72 of them, so the work in front of you is 34 controls, not 106, which is 32% of the standard rather than all of it.
That is the whole claim. Every number in that sentence comes from the two counts above it and can be re-derived from the free tools without taking our word for any of it.
In money, using only our numbers. The full report is $299 and names 72 controls of NIST Cybersecurity Framework 2.0 you do not have to implement again, which is $4.15 per control identified. That arithmetic uses our price and our count and assumes nothing about you.
In your hours, using your assumption. We do not know what a control costs you to implement, so pick the column that looks like your organisation. These are your figures, not our claim.
| If a control takes you | 4 hours | 8 hours | 16 hours |
|---|---|---|---|
| the 72 already evidenced are | 288 hours | 576 hours | 1,152 hours |
| and the 34 remaining are | 136 hours | 272 hours | 544 hours |
Multiply by your own rate. We publish no rate because we have not measured yours, and a number built on an invented rate is the kind of claim this platform exists to argue against.
This number is directional. It says how much of NIST Cybersecurity Framework 2.0 your NIST SP 800-53 Rev 5 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.
462 candidate mappings were examined and 330 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.
SI-4 requires monitoring to detect attacks and analyzing indicators of potential events.
AU-6 requires analysis of audit records for indications of inappropriate activity.
AU-6 requires correlating audit records across repositories to gain situational awareness.
SI-4 requires monitoring inbound and outbound network communications for adverse events.
PE-6 requires monitoring physical access and responding to detected incidents.
SI-4 requires monitoring for unauthorized use of the system by personnel.
SA-9 requires monitoring external provider control compliance on an ongoing basis.
PM-11 requires defining mission and business processes with security risk considered.
Claims that did not hold
324 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.
Not corroborated on review of this pair by Claude Code
Claimed at medium confidence before it was rejected.
did not survive the adversarial verification pass run by qwen3-235b-a22b-2507 via openrouter. No per-edge rationale was recorded at the time, so the process is stated rather than a reason invented.
