NIST SP 800-171 Rev 3 covers 58.2% of HIPAA Security Rule
39 of the 67 controls in HIPAA Security Rule are already satisfied by evidence you collected for NIST SP 800-171 Rev 3. 28 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 HIPAA Security Rule 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.
124 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 covers likelihood and impact of unauthorised access, disclosure, modification and destruction.
Continuous monitoring strategy and status reporting satisfy the ongoing sufficiency test.
Plan of action and milestones is the prioritised remediation record tracked to closure.
Risk response requires accepting, transferring, mitigating or avoiding each assessed finding.
Audit records reviewed at defined frequency for unusual activity with findings reported.
Access enforcement against approved authorisations prevents those who should not have access from obtaining it.
Account management authorises access, assigns managers, monitors use and re-authorises periodically.
Personnel screened before access is authorised and rescreened at defined frequency.
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.
