SOC 1

SOC 1. A SOC 1 report is a formal attestation examination performed by an independent Certified Public Accountant (CPA) firm, focusing on the design and operating effectiveness of a service organization's internal controls relevant to a user entity's financial statement assertions. Issued under the Statement on Standards for Attestation Engagements (SSAE) 18, it is a critical tool for outsourcing and cloud computing arrangements where a third-party service provider, such as a payroll processing company or a financial transaction processor, impacts their clients' financial reporting. The report provides assurance to the service organization's customers (user entities) and their auditors (user auditors) that the controls over the services provided are suitably designed and, in a Type 2 report, operating effectively over a specified period.

Overview

The SOC 1 framework was established by the American Institute of Certified Public Accountants (AICPA) to replace the older SAS 70 standard, providing a more rigorous and principles-based approach for reporting on controls at service organizations. Its primary objective is to enable public companies and other entities to fulfill their own Sarbanes-Oxley Act (SOX) compliance obligations by obtaining assurance over their service providers' controls. The examination is conducted in accordance with the Attestation Standards set by the AICPA Auditing Standards Board, and the resulting report is restricted for use by management of the service organization, user entities, and their respective financial statement auditors. The scope is strictly limited to controls that could affect the financial reporting of the user entities, distinguishing it from other SOC reports that address broader operational or security controls.

Types of SOC 1 reports

There are two primary types of SOC 1 reports, defined by the nature of the assurance provided. A **Type 1** report offers an opinion on the fairness of the service organization's description of its system and the suitability of the design of its controls as of a specific point in time, such as the end of a fiscal quarter. In contrast, a **Type 2** report includes everything in a Type 1 report but extends the opinion to also cover the operating effectiveness of those controls throughout a specified period, typically a minimum of six months. The Type 2 report is generally more valuable to stakeholders as it provides evidence that controls were not only well-designed but also consistently applied, and it includes a detailed description of the CPA's tests of controls and the results of those tests, often presented in the form of a control objectives matrix.

Key principles and criteria

The examination is based on key principles derived from the Committee of Sponsoring Organizations of the Treadway Commission (COSO) framework, which is the most widely recognized model for internal control. The service organization must present a description of its system that is fairly presented, and the stated control objectives must be reasonable in the circumstances. The controls are evaluated against the criteria of completeness, accuracy, timeliness, and authorization to determine if they are suitably designed to achieve the related control objectives. For a Type 2 report, the operating effectiveness is assessed by testing whether the controls were applied consistently by competent personnel throughout the period, providing reasonable assurance that the control objectives were achieved.

Relationship to other frameworks

SOC 1 exists within a family of service organization control reports, each with a distinct purpose. While SOC 1 focuses on Internal control over financial reporting (ICFR), SOC 2 reports address controls related to the Trust Services Criteria of security, availability, processing integrity, confidentiality, and privacy. SOC 3 provides a general-use SysTrust or WebTrust seal for public consumption. Internationally, ISAE 3402, issued by the International Auditing and Assurance Standards Board, serves a nearly identical purpose to SOC 1 and is often obtained by multinational organizations serving clients in jurisdictions like the European Union. Many firms undergo a single examination that yields both a SOC 1 and an ISAE 3402 report to satisfy global clients.

Audit process and requirements

The audit process begins with a planning phase where the service organization, its management, and the independent auditor agree on the scope, control objectives, and period to be covered. The service organization prepares a detailed system description, and the auditor performs procedures to obtain evidence about the fairness of that description and the design of controls. For a Type 2 examination, the auditor then performs tests of controls, which may include inspection of documents, observation of processes, inquiries of personnel, and reperformance of control activities. The auditor issues an opinion letter and a detailed report, which includes the service organization's assertion letter from management, the auditor's opinion, the system description, and the results of the tests of controls.

Common uses and stakeholders

SOC 1 reports are predominantly used by service organizations whose services are integral to the financial reporting of their clients. Common examples include application service providers (ASPs), data center operators, loan servicers, claims processing companies, and investment advisors. The primary stakeholders are the user entities (the clients) and their external auditors, who use the report as audit evidence to support their own opinion on financial statements and SOX 404 assessments. Other stakeholders include regulatory bodies such as the Securities and Exchange Commission (SEC), banking regulators, and the management and board of directors of the service organization itself, who use the report for governance and continuous improvement of their control environment.
