SOC 2 vs SOC 3 Compliance: What’s The Difference

The SOC 2 report and SOC 3 report were developed by the AICPA and continue to be the gold standard for SOC reporting on controls at a third-party service provider.

What Is A SOC 3 Report?

A SOC 3 report outlines information related to a service organization’s internal controls for security, availability, processing integrity, confidentiality or privacy. We outline the details of a SOC 2 compliance audit here.

SOC 2 vs. SOC 3 Report Similarities

Before we dive into differences, let’s start with how they are similar. From an auditing perspective, System and Organization Controls (SOC) 2 and SOC 3 audit examinations are nearly identical in that they both are conducted in accordance with the same standards (AT-C Sections 105 and AT-C Section 205) and guidance (SOC 2® Reporting on an Examination of Controls at a Service Organization Relevant to Security, Availability, Processing Integrity, Confidentiality, or Privacy). Both reporting frameworks cover the same subject matter and they are based on the five Trust Services Principles (TSP) (security, confidentiality, availability, privacy and processing integrity). In fact, a SOC 3 report cannot be generated without first executing the steps necessary to complete a SOC 2 examination.

Difference Between SOC 2 and SOC 3 Compliance

Where SOC 2 audit report and SOC 3 audit report examinations differ is in the reporting. Specifically, they vary in use of the report and level of detail contained in the description. The driving force behind the differences between the two reports begins with the intended distribution of the report. A SOC 2 report is a restricted use report that is solely intended for the user entities, management of the service organization, and other specified parties. Meanwhile, a SOC 3 report is a general use report that is freely distributed to the public and is intended for users that are only interested in a broad overview of the service organizations and the service being provided. In general, a SOC 3 audit report is generally used by service organizations for marketing purposes, while a SOC 2 report is better suited for a service organization to provide their user entities that seek details as to how the service organization is performing in maintaining controls to protect their interests.

A summary of the differences between a SOC 2 and SOC 3 are detailed in the table below:

Type I Report Yes, a SOC 2 Type I report is available for service organizations seeking to report on the fairness of the description and suitability of design of controls. No, a SOC 3 report can only be completed on the Type II examination.
Type II Report Yes, a SOC 2 Type II report is available for service organizations seeking to report on the fairness of the description, suitability of design of controls, and operational effectiveness of the controls over a period of time. Although there is no designated Type I or Type II for a SOC 3, a SOC 3 report is required to be performed as a SOC 3 Type II examination.
