What Does a SOC Audit Stand For? Types and Process

SOC stands for System and Organization Controls, referring to a series of independent audits that evaluate a company’s internal controls. These audits help businesses confirm their processes meet standards for security, financial reporting, and data protection. The framework for SOC audits was established by the American Institute of Certified Public Accountants (AICPA), ensuring a standardized evaluation. This framework helps service organizations, which are third parties performing services for other companies, demonstrate their control environment.

Distinguishing SOC Report Types

SOC reports are categorized into different types, each serving distinct purposes and addressing specific aspects of an organization’s controls. The primary types are SOC 1, SOC 2, and SOC 3, with SOC 1 and SOC 2 further distinguished by Type 1 and Type 2 reports.

A SOC 1 report focuses on a service organization’s internal controls over financial reporting (ICFR). These reports are particularly relevant for businesses that provide services impacting their clients’ financial statements, such as payroll processors or investment advisors. These reports assure user entities and their auditors about the reliability of the service organization’s financial processes.

In contrast, a SOC 2 report evaluates a service organization’s controls related to security, availability, processing integrity, confidentiality, and privacy. These five categories are known as the Trust Services Criteria (TSC), with security being a mandatory component for all SOC 2 reports. SOC 2 reports are widely used by technology and cloud service providers to demonstrate adherence to industry security standards.

Both SOC 1 and SOC 2 reports can be issued as either Type 1 or Type 2. A Type 1 report describes the design of controls at a specific point in time and assesses their suitability. It provides a snapshot of the controls in place. A Type 2 report, however, is more comprehensive, evaluating the design and operating effectiveness of controls over a period, typically six to twelve months. This type of report offers greater assurance that controls function consistently as intended.

A SOC 3 report is a general-use version of a SOC 2 report, offering a high-level summary of security controls. Unlike SOC 1 and SOC 2 reports, which have restricted distribution, SOC 3 reports are designed for public distribution. They serve as a tool for companies to showcase their compliance and security posture to a broader audience, including potential clients and stakeholders.

Navigating a SOC Audit

A SOC audit involves several structured stages, from preparation to formal report issuance. This process requires collaboration between the service organization and an independent Certified Public Accountant (CPA) firm, which acts as an unbiased third-party auditor assessing the organization’s controls.

The initial phase involves planning and scoping the audit. This includes choosing the appropriate SOC report type and defining the audit’s scope, including which systems and processes will be evaluated. Organizations often conduct a readiness assessment or gap analysis to identify and address control weaknesses before the formal audit, ensuring preparedness.

During the audit fieldwork, the CPA firm gathers evidence and tests the identified controls. This involves reviewing documentation, examining system configurations, and interviewing personnel to verify controls are designed and operating effectively. For a Type 2 report, this testing covers a defined period to assess the consistent operation of controls. The auditor evaluates whether the organization’s controls uphold relevant SOC standards and requirements.

The final stage is the issuance of the SOC report, which includes the auditor’s opinion on the effectiveness of the controls. An unqualified opinion indicates that the controls are designed and operating effectively. This report provides an independent assessment of the organization’s control environment, shared with user entities.

The Value of SOC Reports

SOC reports provide significant value to service organizations and their clients. They foster trust, transparency, and formal assurance that appropriate controls are in place.

For service organizations, obtaining a SOC report demonstrates a commitment to maintaining effective controls and protecting sensitive data. This provides a competitive advantage. SOC reports also help organizations meet compliance requirements and streamline vendor due diligence. The audit process can also improve internal processes and risk management by identifying weaknesses.

User entities, such as clients, benefit from SOC reports by gaining assurance over controls implemented by their third-party providers. This helps them evaluate outsourcing risks and meet their own compliance obligations. For instance, a financial institution relying on a third-party data processor might request a SOC 1 report to confirm secure handling of financial data. The reports provide insights into the service organization’s control environment, aiding in managing operational and financial risks.
