What’s the purpose of an SSAE 16 audit and should I pursue one? If you’re new to the world of information security audits, check out this comprehensive guide on the history of SSAE 16, why it replaced the SAS 70, and how becoming SSAE 16 compliant could benefit your business.
Outsourcing critical business functions, such as IT or HR, is a common practice among many businesses, today. While outsourcing is a great way to cut operational costs and acquire resources that aren’t available internally, it doesn’t come without its risks. It is especially crucial to consider how outsourcing functions to service organizations could impact your internal control over financial reporting (ICFR).
In accordance with Sarbanes-Oxley (SOX), publicly traded companies are responsible for maintaining an effective system of internal control over financial reporting (ICFR). Such emphasis on governance and risk management when it comes to reporting on controls at a service organization, is the reason many organizations have chosen to require their vendors, who may have an impact on their ICFR, to obtain an SSAE 16 (SOC 1) Attestation Report.
What is SAS 70?
SAS 70 is the Statement on Auditing Standards No. 70, an older auditing standard developed by the American Institute of Certified Public Accountants (AICPA). It provides standards for reporting on controls and processes at service organizations, but, unlike later standards, did not require auditors to obtain a written assertion concerning the design and effectiveness of controls. SAS 70 was superseded by SSAE 16 in 2011, and more recently, by SSAE 18.
What is SSAE 16?
SSAE 16 is the Statements on Standards for Attestation Engagements no. 16. It provides a set of standards and guidance for attestation reporting on organizational controls and processes at service organizations. Audits using SSAE 16 generally result in System and Organizational Control (SOC 1) reports. Unlike earlier standards, SSAE 16 requires a written attestation from a service company’s management, stating that its description accurately represents organizational systems, control objectives, and operational activities that affect customers. SSAE 16 was superseded by SSAE 18 in 2017.
What is SSAE 18?
SSAE 18 is the current set of standards and guidance for reporting on organizational controls and processes at service organizations. It supersedes SSAE 16 and is intended to update and simplify previous standards. Like SSAE 16, SSAE 18 is used in SOC 1 reports, but also in SOC 2 and SOC 3 reports, which were previously conducted under AT 101. Among other changes, SSAE 18 additionally requires that service organizations identify subservice organizations and provide risk assessments to auditors. SSAE 18 is the current standard that SOC 1 audits use.
Out with the Old: Replacing the SAS 70
To make a long story short, CPAs in the past were using the SAS 70 to report on things other than financial reports, however, the SAS 70 was never intended to do so. By introducing a new attestation standard to assess service organizations, the AICPA developed improved assurance by replacing the SAS 70 with the Statement on Standards for Attestation Engagement No. 16, or SSAE 16.
Not only does the SSAE 16 provide a more comprehensive and descriptive assessment of controls, it also allowed user organizations to appropriately assess the reliability of the controls at a service organization.
SSAE 16 vs. SAS 70: What are the Differences?
SAS 70, Cruising with The Auditing Standard
What’s the difference between SSAE 16 and SAS 70? One of the key differences between the SAS 70 and the SSAE 16 is that the SAS 70 is an “auditing” standard, whereas the SSAE 16 is an “attestation”. When the AICPA made the decision to replace the SAS 70, they thought it more appropriate for a service organization audit to be an examination of a system, which is different than an audit of financial statements.
SSAE 16, Going Deeper with Attestation
The SSAE 16 report requires a description of a system along with a written assertion by management on the design and operating effectiveness of the controls being reviewed. The SAS 70, however, lacked the level of detail that the SSAE 16 offers. The SAS 70 simply provided a description of controls and did not include any type of management assertion.
New and Improved: The SSAE 16 Audit Report
The SSAE 16 has been around long enough now to have gained popularity and familiarity by both service organizations and their clients. However, we still receive a fair amount of questions regarding the purpose of an SSAE 16 audit report, the components, and the benefits of a service organization obtaining an SSAE 16 audit report.
Components of an SSAE 16 Audit Report
There are not set controls for an SSAE 16, as each is unique to the service organization and the type of business they are doing. However, there are common criteria and common control objectives that typically make up the components of an SSAE 16 or SOC 1 report. This includes the independent service auditor’s report, management’s written assertion, a description of the system, control objectives and the testing of operating effectiveness of the controls.
Type I vs Type II Reports
There are two basic types of SSAE 16 reports, type I and type II. SSAE 18 SOC 1 reports concern the accuracy of a service company’s description of its controls and systems, and their effectiveness in achieving control objectives. They are similar in many ways, but the key difference is the period of time covered by the report.
- SSAE 1 Type I reports are “point in time” reports; they report on systems and controls at a specified date.
- SSAE 1 Type II reports, in contrast, report on the suitability of controls over a period of time of no less than six months.
It is often recommended that service organizations begin with an SSAE 16 Type I report, and then move to an SSAE 16 Type II report to demonstrate the maturing of their environment.

Benefits of Pursuing an SSAE 16 Audit Report
There are several benefits associated with obtaining an SSAE 16 audit report. First, it is a great way to demonstrate your commitment to delivering high quality services to your clients.
