Customers and business partners of a service organization often request a SOC 2 report to assess the risks of outsourcing to it. source
Categories
Controls are evaluated against criteria for security, availability, processing integrity, confidentiality and privacy. source
Scope
The criteria can be applied to an entire entity, or to a subsidiary, division or other part of it. source
SOC 3
A SOC 3 report is a general-use report on the same categories, covered by the same AICPA guide. source

How compliance is assessed

A CPA examines management's description of the system and its controls and issues a SOC 2 report.

Examination
A SOC 2 engagement is an assertion-based examination of a service organization's description of its system and of its controls relevant to the five categories. source
Criteria used
The CPA uses the 2017 Trust Services Criteria to evaluate controls and the 2018 description criteria to evaluate management's description of the system. source
Who performs it
CPAs in public practice perform SOC 2 and SOC 3 examinations. source

Enforcement and penalties

The AICPA acts on the quality of the CPAs who perform SOC engagements.

Auditor quality
Responding to allegations about a SOC compliance vendor, the AICPA said it will act with respect to its members if auditors are found not to have performed audits under professional standards, not to be enrolled in peer review or to be unlicensed. source
Referrals
The AICPA assists government regulators, including referrals to state boards of accountancy, about unlicensed firms and practitioners. source
