SOC 2 Evidence for AI Usage: Auditor-Ready in 30 Minutes

Four artefacts your auditor will ask for the first time AI usage comes up in a SOC 2 review — and how to generate them without a six-month project.

Artifact 1 — the AUP

One page. Approved services. Disallowed content categories with three concrete examples. Consequences. Version-controlled. Reviewed annually. That's it.

Artifact 2 — the inventory

A spreadsheet of every AI service the company tolerates, the tier employees may use, the DPA on file, the vendor's SOC 2 report on file, and the owner. Update quarterly.

Artifact 3 — the control

A technical control that reduces the probability of sensitive data reaching a public LLM. Redact-before-send at the browser edge is the easiest to explain and the easiest to demonstrate.

Artifact 4 — the evidence

A monthly log of policy exceptions requested and granted, and any incident tickets involving AI usage. Zero exceptions is a red flag; auditors expect friction.

Frequently asked

Is CC6.1 the relevant TSC?+

CC6.1 (logical access) is where most auditors put it, sometimes overlapping with CC7.2 (monitoring).

Does the tool need to be on a SOC 2 report?+

Not always, but a Type II report from the redaction vendor massively shortens the conversation.
