SOC 3 Report: What is it?
Trust Services Report for Service Organization: SOC 3 engagements use the predefined criteria in Trust Services Principles, Criteria, and Illustrations that also are used in SOC 2 engagements.
The key difference between a SOC 2 report and a SOC 3 report is that a SOC 2 report, which is generally a restricted-use report, contains a detailed description of the service auditor’s tests of controls and results of those tests as well as the service auditor’s opinion on the description of the service organization’s system.
A SOC 3 report is a general-use report that provides only the auditor’s report on whether the system achieved the trust services criteria (no description of tests and results or opinion on the description of the system). It also permits the service organization to use the SOC 3 seal on its website. SOC 3 reports can be issued on one or multiple Trust Services principles (.i.e., security, availability, processing integrity, confidentiality, and privacy).
