What is SOC 2 evidence?
SOC 2 evidence is the documentation that demonstrates a control was in place and operating as intended during the examination period, it is what auditors test, and the proof behind every control claim in the report.
Valid evidence types include system-generated logs (access logs, change logs, system activity records), screenshots with timestamps showing system configurations or MFA enforcement, exported reports from security platforms (vulnerability scanners, endpoint protection tools, SIEM systems), signed documents (training completion records, policy acknowledgment forms, background check records), meeting minutes and tickets showing management review activity, vendor contracts and risk assessment records, and configuration outputs showing encryption status, access control settings, or system hardening benchmarks. Evidence must be contemporaneous, created at the time the control operated, not reconstructed after the fact.
What evidence is required for the most common SOC 2 controls?
SOC 2 evidence requirements map directly to control areas, and auditors expect specific documentation for every relevant activity during the observation period, not summaries or assertions.
Access control evidence includes user access provisioning and de-provisioning records for every personnel change during the observation period, documented user access reviews, MFA enforcement reports, and privileged access logs. Change management evidence includes change request tickets with approvals, testing records, and implementation documentation for every in-scope system change. Incident response evidence includes the written plan, documentation of tabletop exercises, and records of any actual incidents with response timelines. Vendor management evidence includes completed risk assessments for all in-scope sub-processors and vendor contracts with security requirements. Training evidence includes completion records showing every employee completed training with dates. Risk assessment evidence includes a dated, documented risk assessment showing identified risks and treatment decisions.
How long must SOC 2 evidence be retained?
SOC 2 does not specify a mandatory retention period in the Trust Services Criteria, but organizations should retain evidence for a minimum of three years. This supports future examinations, allows response to customer inquiries about prior audit periods, and addresses any legal or contractual obligations referencing security compliance history. Evidence from the current observation period must remain accessible throughout audit fieldwork and should be organized and archived immediately after the report is issued. Evidence that cannot be produced during fieldwork, even if the control operated correctly, will be treated by the auditor as a gap.
What happens if evidence from the observation period is missing?
Missing evidence is treated as an exception regardless of whether the control actually operated, auditors cannot attest to a control’s effectiveness based on oral claims. If evidence for a specific sample is missing, the auditor documents it as a deviation. If evidence is missing systematically, no records of user access reviews for a three-month period, for example, the gap will likely result in a finding affecting the auditor’s opinion. Evidence collection must be treated as an ongoing operational activity throughout the observation period, not an exercise conducted retrospectively before fieldwork begins.
