NIST SP 800-172 covers 18% of SOC 2
11 of the 61 controls in SOC 2 are already satisfied by evidence you collected for NIST SP 800-172. 50 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
SOC 2 has 61 controls. Holding NIST SP 800-172 already evidences 11 of them, so the work in front of you is 50 controls, not 61, which is 82% of the standard rather than all of it.
That is the whole claim. We do not know your hourly rate, how long a control takes you, or how many people you have, so there is no figure here in dollars or weeks. 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.
This number is directional. It says how much of SOC 2 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.
41 candidate mappings were examined and 4 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.
Removing CUI no longer needed from persistent storage is disposal of confidential information.
Annual independent penetration testing is a separate evaluation of whether controls function.
Annual assessment of security solution effectiveness is a separate evaluation of control functioning.
Restricting access to organization provisioned resources is a logical access architecture over protected assets.
Bidirectional cryptographic authentication before network connection blocks unauthorized external systems at the boundary.
Secure information transfer solutions control flows crossing the boundary between connected systems.
Secure transfer solutions restrict and protect information moving between security domains.
Root of trust and signature verification of software detects unauthorized or altered code.
Claims that did not hold
4 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.
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.
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.
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.
