SAS 70 vs SSAE 16 vs SSAE 18: Differences for Effective Compliance

When it comes to compliance and auditing standards, the world of information security can be a bit confusing. With the introduction of new standards and the retirement of old ones, it’s important to stay up-to-date on the latest requirements. In this article, I’ll be diving into the key differences between SAS 70, SSAE 16, and SSAE 18. Understanding these distinctions will help you navigate the complex landscape of compliance and make informed decisions for your organization.

SAS 70: Overview and Evolution

The SAS 70 (Statement on Auditing Standards No. 70) was a widely used auditing standard in the early 2000s. It was developed by the American Institute of Certified Public Accountants (AICPA) to help organizations demonstrate their control over financial reporting processes.

Here are some key points about SAS 70:

  1. Purpose: The primary purpose of SAS 70 was to provide assurance to organizations’ customers, auditors, and stakeholders that their internal controls were accurately designed and operating effectively.
  2. Scope: SAS 70 focused primarily on assessing the suitability and effectiveness of an organization’s controls related to financial reporting. It did not address non-financial controls or the security of data and information systems.
  3. Service Auditor’s Report: The SAS 70 assessment was conducted by a third-party service auditor who evaluated and provided a detailed report on an organization’s controls. This report was then shared with customers, auditors, and other interested parties.
  4. Retirement of SAS 70: In 2011, the SAS 70 was officially retired and replaced by the SSAE 16 (Statement on Standards for Attestation Engagements No. 16). The retirement of SAS 70 was driven by the need for a more comprehensive and globally recognized standard for service organization reporting.
  5. Evolution to SSAE 16 and SSAE 18: The SSAE 16 enhanced the SAS 70 by aligning it with international standards and introducing more stringent reporting requirements. Later, in 2017, SSAE 16 was replaced by SSAE 18, which further enhanced controls and reporting standards.
  6. Key Differences: The key differences between SAS 70, SSAE 16, and SSAE 18 lie in the comprehensiveness of the assessments, reporting requirements, and the focus on controls beyond financial reporting.

The SAS 70 was an important auditing standard in the early 2000s, primarily focusing on financial reporting controls. However, it was retired and replaced by the more comprehensive SSAE 16 and SSAE 18 to align with international standards and meet the evolving needs of organizations and stakeholders.

SSAE 16: Introduction and Updates

SSAE 16, or Statement on Standards for Attestation Engagements No.16, is a standard that was introduced to replace the outdated SAS 70 audit standard.

The SAS 70, widely used in the early 2000s, focused primarily on financial reporting controls. However, as technology advanced and the need for more comprehensive assessments became evident, the SAS 70 was retired to make way for a more robust and internationally aligned standard: the SSAE 16.

The introduction of SSAE 16 brought about significant updates and improvements in the field of information security auditing. Here are some key aspects of the SSAE 16 standard:

  1. Expanded Coverage: Unlike the SAS 70, which solely focused on financial reporting controls, the SSAE 16 widened its scope to include a broader range of controls. This expansion ensures that organizations undergo a comprehensive assessment that covers all aspects of their operations, including IT infrastructure, data security, and more.
  2. More Detailed Reporting: The SSAE 16 standard requires more detailed reporting compared to the SAS 70. This means that auditors are required to provide a comprehensive evaluation of an organization’s controls, identify any deficiencies, and recommend necessary improvements. The increased level of transparency in reporting allows stakeholders to make well-informed decisions regarding an organization’s security posture.
  3. Alignment with International Standards: With the retirement of the SAS 70, there was a need to align auditing standards with global best practices. The SSAE 16 was developed to meet this requirement and ensure consistency across international boundaries. This alignment allows organizations to demonstrate their commitment to information security in a globally recognized manner.

It is essential for organizations to understand the differences between SAS 70, SSAE 16, and other auditing standards to make informed decisions regarding compliance. The retirement of SAS 70 and the introduction of SSAE 16 brought about significant improvements to the auditing process, ensuring a more comprehensive evaluation of an organization’s controls and aligning with international standards.

SSAE 18: The New Standard

The retirement of SAS 70 and the introduction of SSAE 16 marked a significant shift in the auditing and compliance landscape. However, the evolution didn’t stop there. With the introduction of SSAE 18, organizations now have an even more comprehensive and robust standard to adhere to. Let’s explore what makes SSAE 18 the new industry benchmark.

  1. Enhanced reporting: One of the key advancements of SSAE 18 is its emphasis on more detailed reporting. While SAS 70 focused primarily on financial reporting controls, SSAE 18 requires auditors to go beyond the numbers. This means a stronger focus on controls related to information security, availability, processing integrity, confidentiality, and privacy.
  2. Broader assessment scope: Unlike its predecessor, SSAE 18 expands its coverage to a wider range of controls. It takes into account not only financial reporting controls but also operational controls that are crucial for organizations. This makes the assessment more comprehensive, providing stakeholders with a holistic view of an organization’s compliance.
  3. Alignment with international standards: Recognizing the need for global harmonization, SSAE 18 aligns with internationally recognized standards, particularly with the International Standard on Assurance Engagements (ISAE) 3402. This alignment ensures that organizations complying with SSAE 18 are well-positioned to meet global compliance requirements.
  4. Focus on risk assessment: SSAE 18 places greater importance on risk assessment as a fundamental part of the evaluation process. Auditors are required to understand an organization’s risk landscape, identify potential threats, and evaluate the effectiveness of controls in mitigating those risks. This risk-based approach strengthens the overall audit process and helps organizations prioritize their compliance efforts.
  5. Ongoing monitoring and evaluation: SSAE 18 introduces the concept of continuous monitoring and evaluation. Auditors are encouraged to review controls on an ongoing basis to ensure their effectiveness and compliance with the standard. This dynamic approach enables organizations to adapt to evolving threats and maintain a strong security posture.

As organizations strive for compliance and seek to address the ever-changing information security landscape, understanding the differences between SAS 70, SSAE 16, and SSAE 18 becomes crucial. Embracing the new standard, SSAE 18, can empower organizations to meet the demands of stakeholders, demonstrate a commitment to good governance, and build trust in an increasingly interconnected world.

Key Differences Between SAS 70, SSAE 16, and SSAE 18

When it comes to auditing standards in the field of information security, it’s important to understand the key differences between SAS 70, SSAE 16, and SSAE 18. These standards have evolved over the years, with each new iteration addressing the changing needs and complexities of the industry.

  1. SAS 70 (Statement on Auditing Standards No. 70): Introduced in 1992, SAS 70 was the first widely recognized auditing standard for service organizations. It focused on evaluating the controls and processes implemented by service providers to safeguard their clients’ data. However, as technology advanced and the need for more comprehensive assessments grew, SAS 70 became outdated.
  2. SSAE 16 (Statement on Standards for Attestation Engagements No. 16): In 2011, SSAE 16 replaced SAS 70 as the new auditing standard. One of the key differences between SAS 70 and SSAE 16 is the shift from a “report on controls” to a “report on the description of controls.” This change aimed to provide more transparency to users of service organizations’ systems and controls.
  3. SSAE 18 (Statement on Standards for Attestation Engagements No. 18): SSAE 18, introduced in 2017, further improved upon the deficiencies of SSAE 16. It expanded the scope of assessments to include the evaluation of the design and operating effectiveness of controls over a specified period of time. This shift emphasizes the ongoing monitoring and evaluation of controls, rather than just a snapshot in time.

Here are some key differences between SSAE 16 and SSAE 18:

  • Reporting Requirements: SSAE 18 introduced new reporting requirements, including the requirement to disclose any significant incidents or control failures that occurred during the assessment period. This enhanced reporting provides users of the report with more comprehensive insights into the effectiveness of controls.
  • Assessment Scope: SSAE 18 broadened the assessment scope by requiring service auditors to evaluate the risk of material misstatement related to the subject matter of the engagement. This ensures a more comprehensive assessment of controls and helps organizations identify and address potential risks.

Impact on Compliance and Auditing Processes

One of the key reasons for the retirement of SAS 70 and the introduction of SSAE 16 and SSAE 18 was the need to adapt to the constantly evolving landscape of compliance and auditing processes. These changes have had a significant impact on how organizations approach their compliance efforts and how auditors assess controls. Let’s delve into the specific impacts of these standards:

  1. Enhanced Reporting Requirements: SSAE 16 and SSAE 18 have introduced more rigorous reporting requirements compared to SAS 70. These new standards aim to provide stakeholders with greater transparency and assurance by requiring service organizations to provide a detailed description of their controls and an assessment of their effectiveness.
  2. Broader Assessment Scope: While SAS 70 primarily focused on controls over financial reporting, SSAE 16 and SSAE 18 expanded the assessment scope to include a wider range of subject matters. This broader scope enables auditors to evaluate controls related to data security, privacy, availability, and processing integrity, among others. Organizations are now required to assess and communicate their controls in a more comprehensive manner.
  3. Alignment with International Standards: SSAE 18 aligns more closely with international auditing standards such as ISAE 3402. This alignment ensures that organizations can demonstrate compliance not only within their local jurisdictions but also across international markets, providing a consistent framework for audits and facilitating global business operations.
  4. Focus on Risk Assessment: Unlike SAS 70, which primarily focused on control activities, SSAE 16 and SSAE 18 emphasize the importance of risk assessment. Service organizations are now required to evaluate the design and operating effectiveness of their controls over a specified period of time. This shift encourages a more proactive approach to risk management and helps organizations identify and mitigate potential risks more effectively.
  5. Ongoing Monitoring and Evaluation: SSAE 18 introduced the concept of ongoing monitoring and evaluation, requiring service organizations to continuously assess and report on the effectiveness of their controls. This aspect ensures that controls are not just implemented but also monitored for their ongoing effectiveness, reducing the risk of control failures between audits.

These changes have had a profound effect on compliance and auditing processes. Organizations must adapt to the enhanced reporting requirements, broader assessment scope, and increased focus on risk assessment and ongoing monitoring. By doing so, they can ensure that they meet compliance requirements, demonstrate good governance, and build trust in an interconnected world.
