Attestation Standard Section 801 (AT 801) is a standard designed for service organizations (like AWS) to independently report on compliance with policies, procedures and controls. It provides guidance to the auditors who assess AWS as a service organization. The AWS SOC 1 Report is prepared in accordance with AT 801 by our independent service auditors (Ernst & Young, LLP) and provides an assurance report and independent auditor’s opinion on AWS internal controls that may be relevant to a customer’s internal control over financial reporting. AT 801 is issued by the Auditing Standards Board (ASB) of the American Institute of Certified Public Accountants (AICPA) and supersedes the two prior service organization controls guidance standards for auditors commonly known as SSAE 16 and SAS 70.

The AWS SOC 2 Security, Availability, & Confidentiality and SOC 3 Security, Availability, & Confidentiality Reports are prepared in accordance with Attestation Standard Section 101 (AT 101) which is a standard that enables an auditor to report on subject matter other than financial statements based on the AICPA Guide Reporting on Controls at a Service Organization Relevant to Security Availability, Processing Integrity, Confidentiality, or Privacy and Trust Services Principles and Criteria.

Ernst & Young LLP performs the AWS SOC 1, SOC 2 and SOC 3 audits.

AWS issues two SOC 1, SOC 2, and SOC 3 Reports covering 6-month periods each year (the first report covers October 1 – March 31 and the second report covers April 1 – September 30). New reports are released in mid-May and mid-November.

The AWS SOC 1 Audit is conducted in accordance with International Standards for Assurance Engagements No. 3402 (ISAE 3402). Customers needing an ISAE 3402 Report should request the AWS SOC 1 Type II Report.

An NDA is only required to review the AWS SOC 1 and 2 reports; the AWS SOC 3 report is publicly available here. The AWS SOC 3 report is a summary of the AWS SOC 2 report. It outlines that AWS meets the AICPA’s Trust Security Principles in SOC 2 and includes the external auditor’s opinion of the operation of controls.

The AWS SOC 1 and SOC 2 report is available to customers using AWS Artifact, a self-service portal for on-demand access to AWS’ compliance reports. Get started with AWS Artifact today.

The AWS SOC 3 is publicly available and can be found here.
