What Is the Difference Between SOC 2 & SOC 3 Attestation Services?

What’s the Difference Between SOC 2 & SOC 3 Attestation Services?

In today’s digital ecosystem, organizations handling sensitive customer data must demonstrate trust, security, and compliance. Two widely recognized frameworks for this are SOC 2 and SOC 3. While both are built on the AICPA’s Trust Services Criteria, they serve different audiences and purposes. Understanding these differences helps businesses choose the right report to strengthen their credibility and transparency.

What Is SOC 2?

SOC 2 attestation services are designed specifically for service organizations that store, process, or manage customer data. SOC 2 focuses on five Trust Services Criteria (TSC):

  • Security

  • Availability

  • Processing Integrity

  • Confidentiality

  • Privacy

SOC 2 reports come in two types—Type I (design effectiveness) and Type II (operating effectiveness over time). These reports are detailed and intended for auditors, customers, and prospects who require assurance on internal controls.

What Is SOC 3?

SOC 3 reports are also based on the same Trust Services Criteria but are less technical and designed for public use. Unlike SOC 2, SOC 3 reports do not include detailed descriptions of testing procedures or control results. This makes SOC 3 ideal for marketing, website badges, and trust building with a wider audience.

Key Differences Between SOC 2 & SOC 3 Attestation Services

Below are the major distinctions that help organizations understand which report suits their goals:

1. Audience & Purpose

SOC 2

  • Intended for clients, auditors, and stakeholders needing detailed assurance.

  • Used during vendor assessments or due-diligence processes.

SOC 3

  • Public-facing report for general audiences.

  • Suitable for marketing materials, websites, and trust-building.

2. Level of Detail

SOC 2 Attestation Services

  • Provides in-depth documentation of controls, testing, findings, and auditor opinion.

  • Includes sensitive information (e.g., system architecture, security controls).

SOC 3

  • High-level summary without revealing technical or sensitive details.

  • Safe to publish online.

3. Report Distribution

SOC 2

  • Restricted distribution—shared only with customers under NDA.

  • Not allowed for public posting.

SOC 3

  • Public report—can be posted on websites and shared freely.

  • Helps showcase compliance to all users.

4. Use Cases

SOC 2

  • Required by B2B clients and enterprise customers.

  • Used to satisfy compliance, vendor audits, and security questionnaires.

SOC 3

  • Ideal for brand credibility and public communication.

  • Helps companies signal security without disclosing internal details.

Which One Should You Choose?

Organizations that need to demonstrate comprehensive control effectiveness should opt for SOC 2 attestation services, especially when working with enterprise clients. However, if your goal is broad public trust and marketing visibility, a SOC 3 report is a powerful complement.

Many companies choose to obtain both—using SOC 2 for contractual clients and SOC 3 for public assurance.

Final Thoughts

Both SOC 2 and SOC 3 help build trust, but their purpose and depth vary significantly. Businesses aiming for strong information security credibility should start with SOC 2 attestation services, then use SOC 3 to communicate that achievement publicly. Together, they form a complete compliance and trust-building strategy.
