SOC 2 vs SOC 3: What’s the Difference and Which One Do You Need?

As business owners of SaaS firms, navigating the world of SOC compliance and regulations can be challenging due to its complex legal language, audits, and other requirements. Nonetheless, data security is paramount; therefore, it is beneficial to explore this landscape with a thorough understanding of the SOC (Service Organization Control) reporting framework.

In this article, we compare SOC 3 vs. SOC 2 compliance, discussing their similarities and differences.

¿Qué es un informe SOC 2?

A Informe SOC 2 is a detailed description of your SOC 2 audit process. It is an evaluation by an independent certified auditor of whether your business provides a secure, available, confidential, and private solution to your customers. The auditor releases the report after examining your organization’s control over one or more of your chosen Trust Services Criteria (TSC). SOC 2 Type 2 evaluates control effectiveness over an observation period. Before choosing between SOC 2 and SOC 3.

The SOC 2 report contains the auditor’s detailed opinion on the design and operational effectiveness of your organization’s internal controls.  It is, in essence, a testament to the strength of your information security practices. It is meant to enable the report users (your customers and customers’ customers) to assess and address the risks arising from their relationship with your organization.

¿Qué es un informe SOC 3?

A Informe SOC 3 is a public account of your organization’s internal controls over the chosen TSC (Security, Availability, Confidentiality, Processing Integrity, or Privacy). While it shares similarities with SOC 2 in scope, it offers a relatively general overview of how your organization approaches data security.  Therefore, organizations use them for marketing purposes to amplify their security readiness to prospective customers.

According to the American Institute of Certified Public Accountants (AICPA), a SOC 3 report is, ‘designed to meet the needs of users who need assurance about the controls at a service organization relevant to data security, availability, processing integrity, confidentiality, or privacy, but do not require or the knowledge necessary to make effective use of a SOC 2 Report.

SOC 2 vs SOC 3: Key Differences

The key difference in the SOC 2 vs SOC 3 reports is in the reporting, whereas in general, SOC 3 reports are less exhaustive than SOC 2 reports.

1. Scope of the report

SOC 2 reports offer a detailed and comprehensive view of your audit. They include the auditor’s opinion, management assertion, system description, control testing, and the test results. This level of depth is often regarded as the gold standard for vendor assurance, as customers rely on it during the onboarding process.

SOC 3 reports, on the other hand, offer only a summarized view. They confirm that your controls meet the Trust Services Criteria but exclude all control descriptions and testing details.

2. Intended use of the report

SOC 2 reports are restricted-use documents intended for internal teams, customers, and customer auditors. They are typically reviewed during vendor risk assessments.

SOC 3 reports are designed for general use. They can be shared publicly, and many organizations publish them on their website to highlight their security posture. This is why SOC 3 is often referred to as a marketing-friendly version of SOC 2.

3. SOC 3 report vs SOC 2 type

SOC 2 reports are categorized into Type I and Type II. Type I offers a point-in-time view of control design, while Type II evaluates how those controls operated over a period.

SOC 3 reports are issued only in Type II format. They follow the same Trust Services Criteria as SOC 2 but present the results in a simplified, public-facing format without disclosing any testing evidence.

SOC 2 vs SOC 3: Price Differences

The primary cost difference between SOC 2 and SOC 3 primarily stems from the audit effort and the depth of reporting.

A SOC 2 audit is far more detailed, requires extensive evidence collection, and involves rigorous control testing, so it naturally costs more. SOC 3, being a summarized version of SOC 2, doesn’t require a separate full audit, which keeps the cost lower.

En la mayoría de los casos:

• SOC 2 is the primary cost driver. A SOC 2 Type I audit typically ranges from $5,000 to $25,000, while a SOC 2 Type II audit ranges from $7,000 to $50,000. When you factor in readiness work, tooling, internal time, and hidden costs, the total SOC 2 compliance investment typically ranges from $30,000 to $150,000.
• SOC 3 is usually an add-on deliverable derived from your SOC 2 audit. Because no additional testing is required, the incremental cost is minimal—often bundled or charged as a small administrative fee by the auditor.
  

For most organizations, the real investment is in SOC 2; SOC 3 becomes an optional, public-facing summary report built upon it.

SOC 2 vs SOC 3 Report Similarities

To best appreciate the differences between SOC 2 vs SOC 3 report, let’s first dive into their similarities.

Alcance de auditoría

The two frameworks are based on the five principles laid down by the AICPA’s Trust Services Criteria – data security, confidentiality, availability, privacy and processing integrity. The organization chooses the TSCs based on the services it provides to its customers. 

Here’s a quick overview of the five Trust Services Criteria.

• Seguridad 

It must be in scope for every SOC 2 audit and is, therefore, referred to as the common criteria. It requires you to enable access the Controles SOC 2, entity-level controls, firewalls, and other operational/governance controls to protect your data and applications. This TSC takes substantial effort and will require participation from your IT Development, IT Infrastructure, HR, senior management, and operations teams.

• Disponibilidad

The Availability criteria in SOC 2 focus on minimizing downtime and requires you to demonstrate that your systems meet operational uptime and performance standards. It includes network performance monitoring, disaster recovery processes, and procedures for handling data security incidents, among others. Business continuity, data recovery and backup plans are critical pieces here.  

• Confidencialidad 

This principle requires you to demonstrate the ability to identify and safeguard confidential information throughout its lifecycle by establishing access control and proper privileges (to ensure that data can be viewed/used only by the authorized set of people or organizations). Confidential data includes financial information, intellectual property, and any other form of business-sensitive details specific to your contractual commitments with your customer. 

• Integridad de procesamiento 

This principle assesses whether your cloud data is processed accurately, reliably, and on time and if your systems achieve their purpose. It includes quality assurance procedures and Herramientas SOC to monitor data processing. This is relevant for businesses that execute critical customer operations such as financial processing, payroll services, and tax processing, to name a few.

• Privacidad

It requires you to protect Personally Identifiable Information (PII) from breaches and unauthorized access through rigorous access controls, two-factor authentication, and encryption. Privacy is relevant to you if your business stores customers’ PII data such as healthcare data, birthdays, and social security numbers.

SOC 2 vs SOC 3 Audit Estándar

Both audit processes are based on the same standards (AT-C Sections 105 and AT-C Section 205) and guidance. For that matter, you cannot generate a SOC 3 report without first complying with the requirements for a SOC 2 report.

Who can perform the audit?

When it comes to the auditing process, there isn’t much difference between SOC 2 and SOC 3. Both SOC 2 and SOC 3 audits require an independent CPA firm specializing in security and compliance assessments. For organizations new to this space, understanding how security differs from compliance clarifies why being compliant doesn’t automatically mean being secure. The auditor should have proven experience in evaluating information security controls and must remain fully independent, meaning they should have no ties to your board of directors or executive team.

Once you select your SOC 2/SOC 3 auditor, you can onboard them directly into Sprinto’s secure dashboard for a streamlined audit experience. This allows you to grant role-based access, share SOC 2 and SOC 3 evidence, respond to queries, communicate with the audit team, and track audit progress from a single location.

How to choose between the SOC 2 vs the SOC 3 Report

In our experience, organizations typically begin with a SOC 2 Tipo 1 or SOC 2 Tipo 2 report before proceeding to a SOC 3 report. This is because a SOC 3 report cannot be generated without first complying with the requirements for a SOC 2 report. Additionally, SOC 3 requires the same level of planning and audit process preparation as a SOC 2 Type II report. Many organizations, therefore, decide to add SOC 3 only after getting their SOC 2 Type II reports.
