Agree on a secure sharing method and limit access to the people who need the evidence. Before uploading, check for credentials, customer content, personal information, and unrelated records. Ask the auditor whether a reduced export or redacted copy will meet the testing purpose. Keep enough identifiers and context to make the evidence understandable, and document meaningful redactions. Do not alter the source record to hide an exception. Establish retention and access-removal responsibilities for the evidence workspace. A well-organized, restricted evidence package is easier to review than a broad export containing information the audit never needed.
