SOC 1 vs SOC 2 vs SOC 3: Which Report Does Your Company Need?

Not all SOC reports serve the same purpose, and selecting the wrong report type is one of the most common and costly mistakes organizations make when approaching a SOC engagement. Understanding the differences between SOC 1, SOC 2, and SOC 3 reports and matching the right report to your business model and stakeholder requirements is the foundation of a SOC program that delivers real value.

SOC 1 reports focus on internal controls relevant to a client's financial reporting. They're most applicable to service organizations whose processes directly affect the financial statements of the businesses they serve. Payroll processors, loan servicers, third-party administrators, and organizations that manage financial transactions on behalf of clients are typical candidates for SOC 1 reporting.

There are two types of SOC 1 reports. A Type 1 report assesses whether controls are suitably designed at a specific point in time. A Type 2 report evaluates both the design and the operating effectiveness of those controls over a defined period, typically six to twelve months. Most clients and auditors require a Type 2 report because it assures how controls actually functioned, not just how they were designed.

Organizations that process transactions, manage financial data, or provide outsourced accounting or administrative functions should evaluate whether a SOC 1 report is required by their clients or by the auditors of their clients.

SOC 2 reports evaluate controls related to one or more of five Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy. Security is required in every SOC 2 engagement. The remaining criteria are selected based on the nature of the organization's services and the expectations of its stakeholders.

SOC 2 reports are most relevant for technology companies, SaaS providers, data processors, managed service providers, and any organization that stores, processes, or transmits sensitive client data. As data security expectations have grown across industries, SOC 2 has become a standard requirement in vendor due diligence processes across financial services, healthcare, manufacturing, and professional services.

Like SOC 1, SOC 2 reports are available in Type 1 and Type 2 formats. A Type 2 report covering a full twelve-month period provides the strongest level of assurance and is what most enterprise clients and regulated industries require.

SOC 3 reports cover the same Trust Services Criteria as SOC 2 but are designed for general public distribution. Unlike SOC 2 reports, which are restricted to clients and stakeholders with a need to know, SOC 3 reports can be posted on a company website or shared with prospective clients as a general indicator of compliance.

SOC 3 reports don't include the detailed description of controls and testing results that make SOC 2 reports useful for due diligence purposes. They're better understood as a marketing and credibility tool than a deep assurance document. Organizations that already have a SOC 2 report can typically produce a SOC 3 with minimal additional effort. They're better understood as a trust signal for prospective clients than a deep assurance document.

The most reliable way to determine which SOC report you need is to ask the clients, auditors, and regulators who'll be requesting it. Client contracts, RFP requirements, and vendor assessment questionnaires often specify which report type is expected. If your clients' auditors are asking for a SOC 1, a SOC 2 won't satisfy that requirement.

If your organization's services directly affect the financial reporting of your clients, a SOC 1 is likely the right starting point. If your organization stores or processes sensitive client data, a SOC 2 is typically more appropriate. Some organizations need both, particularly those that provide financial processing services and also manage sensitive data in the same environment.
