SOC 2NIST SP 800-53 Rev 5

SOC 2 covers 22% of NIST SP 800-53 Rev 5

66 of the 300 controls in NIST SP 800-53 Rev 5 are already satisfied by evidence you collected for SOC 2. 234 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 800-53 Rev 5 your SOC 2 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.

752 candidate mappings were examined and 587 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.

SOC2-CC6.2NIST800-AC-2argued against and upheld
Account management

Users are registered and authorized, and access is removed when no longer appropriate.

SOC2-CC6.1NIST800-AC-3argued against and upheld
Access enforcement

Logical access security software and architectures enforce approved authorizations.

SOC2-CC6.7NIST800-AC-4argued against and upheld
Information flow enforcement

Transmission and movement of information is restricted to authorized users and processes.

SOC2-CC6.3NIST800-AC-5argued against and upheld
Separation of duties

Segregation of duties is explicitly considered when access is authorized.

SOC2-CC6.3NIST800-AC-6argued against and upheld
Least privilege

Least privilege is explicitly considered when access is authorized or modified.

SOC2-CC7.2NIST800-AU-2argued against and upheld
Event logging

Monitoring system components for anomalies requires the events this control selects for logging.

SOC2-CC7.2NIST800-AU-6argued against and upheld
Audit record review, analysis, and reporting

Anomalies are analyzed to determine whether they indicate malicious acts, which is record review.

SOC2-CC4.1NIST800-CA-2argued against and upheld
Control assessments

Ongoing and separate evaluations ascertain whether controls are present and functioning.

Claims that did not hold

578 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.
