  • Unlike ISO 27001, SOC 2 produces an attestation report, not a certificate

What is SOC 2?

SOC 2 (System and Organization Controls 2) is an auditing framework developed by the American Institute of Certified Public Accountants (AICPA). It evaluates how well a service organization protects customer data based on five Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality, and Privacy.

Unlike ISO 27001, which results in a certificate, SOC 2 produces an independent auditor's report (attestation) issued by a licensed CPA firm. This report provides detailed information about your controls and whether they meet the criteria.

SOC 2 in a Nutshell

What: Auditing framework for service organizations
Who: Any company that stores, processes, or transmits customer data
Output: CPA auditor's report (not a certificate)
Standard: AICPA Trust Services Criteria
Recognition: Primarily North America, increasingly global

History and Background

SOC 2 emerged from the evolution of SAS 70 (Statement on Auditing Standards No. 70), which was replaced by the SOC framework in 2011. The AICPA created three SOC report types:

  • SOC 1: Internal controls over financial reporting (for service providers affecting client financial statements)
  • SOC 2: Controls relevant to security, availability, processing integrity, confidentiality, and privacy
  • SOC 3: Same criteria as SOC 2, but a simplified public report

SOC 2 has become the de facto standard for technology and SaaS companies demonstrating security to US enterprise customers.

The Five Trust Services Criteria

SOC 2 is built around five Trust Services Criteria (TSC). Security is always required; the other four are optional based on your services and customer needs.

1. Security (Required)

Also known as: Common Criteria
Focus: Protection against unauthorized access, use, or modification

Security is the foundation of every SOC 2 report. It covers:

  • Access controls (logical and physical)
  • System operations monitoring
  • Change management
  • Risk mitigation
  • Incident response

2. Availability (Optional)

Focus: System availability for operation and use as committed

Include this if you make uptime commitments (SLAs). It covers:

  • Performance monitoring
  • Disaster recovery
  • Business continuity
  • Incident handling for availability
  • Capacity management

3. Processing Integrity (Optional)

Focus: System processing is complete, valid, accurate, timely, and authorized

Include this if you process transactions or data that must be accurate. It covers:

  • Input validation
  • Processing accuracy
  • Output verification
  • Error handling

4. Confidentiality (Optional)

Focus: Information designated as confidential is protected as committed

Include this if you handle confidential business information (not personal data—that's Privacy). It covers:

  • Confidential data identification
  • Protection measures
  • Disposal procedures
  • Disclosure controls

5. Privacy (Optional)

Focus: Personal information is collected, used, retained, disclosed, and disposed of properly

Include this if you collect and process personal data. It covers:

  • Privacy notice
  • Consent mechanisms
  • Data subject rights
  • Third-party disclosures
  • Data retention and disposal
Which Criteria to Include?

Most organizations start with Security + Availability. Add Confidentiality if handling business secrets, Processing Integrity if doing financial calculations, and Privacy if you're the data controller (not just processor) for personal data.

Who Needs SOC 2?

SOC 2 is particularly important for service organizations—companies that provide services involving customer data. Common examples:

Industries Commonly Requiring SOC 2

  • SaaS Companies: Any cloud software provider
  • Cloud Service Providers: IaaS, PaaS providers
  • Data Centers: Colocation and managed hosting
  • Managed Service Providers: IT outsourcing, managed security
  • Payment Processors: Financial transaction handling
  • Healthcare Technology: EHR systems, health tech
  • HR/Payroll Providers: Employee data processors
  • Financial Services: Fintech, wealth management platforms

Signs You Need SOC 2

  • Enterprise customers ask for it in security questionnaires
  • You've lost deals because you don't have it
  • Your sales cycle is extended by security reviews
  • Competitors have SOC 2 and you don't
  • You're expanding into the US enterprise market

Benefits of SOC 2

1. Win Enterprise Deals

SOC 2 is table stakes for selling to US enterprises. Without it, you may not make it past procurement's security review. With it, you can satisfy security requirements with a single document rather than lengthy questionnaires.

2. Shorten Sales Cycles

Instead of weeks of back-and-forth on security questionnaires, you provide your SOC 2 report. Enterprise buyers know how to read them and trust the independent audit.

3. Competitive Differentiation

In crowded markets, SOC 2 sets you apart from competitors who can only say "we take security seriously" without third-party validation.

4. Improved Security Posture

The process of achieving SOC 2 forces you to formalize controls, document procedures, and address gaps. Most organizations emerge with genuinely better security.

5. Reduce Vendor Security Questionnaires

While you won't eliminate questionnaires entirely, a SOC 2 report answers 60-80% of typical questions, significantly reducing the burden.

6. Customer Trust

SOC 2 demonstrates commitment to security through independent verification, not just marketing claims.

Type I vs Type II Reports

SOC 2 comes in two flavors:

Aspect SOC 2 Type I SOC 2 Type II
What it assesses Design of controls at a point in time Design AND operating effectiveness over a period
Time period Single date 3-12 month period (typically 6-12)
Testing Inquiry, observation, inspection Inquiry, observation, inspection, re-performance, sample testing
Assurance level Lower (design only) Higher (design + operation)
Customer acceptance Some accept as interim step Strongly preferred/required
Timeline 2-4 months 6-15 months total
Cost $15,000-40,000 $30,000-100,000+

Most enterprise customers want Type II. Type I is acceptable as a stepping stone while you build the track record for Type II, but don't expect it to satisfy sophisticated buyers long-term.

What's in a SOC 2 Report?

A SOC 2 report typically contains:

Section 1: Auditor's Report

The CPA firm's opinion on whether your controls are suitably designed (Type I) and/or operating effectively (Type II). This is what customers look at first.

Section 2: Management's Assertion

Your company's statement that the system description is accurate and controls meet the criteria.

Section 3: System Description

Detailed description of your services, infrastructure, software, people, procedures, and data. This helps users understand what's being assessed.

Section 4: Trust Services Criteria and Controls

Mapping of the criteria to your specific controls and how they address each requirement.

Section 5: Tests of Controls (Type II only)

Description of testing procedures performed and results for each control. This is where exceptions are documented.

Section 6: Other Information (Optional)

Additional information provided by management, not covered by the auditor's opinion.

Frequently Asked Questions

What is SOC 2 compliance?

SOC 2 is a framework developed by the AICPA that evaluates service organization controls for security, availability, processing integrity, confidentiality, and privacy. It results in an independent attestation report issued by a licensed CPA firm, providing detailed assurance about an organization's controls to customers and stakeholders.

What is the difference between SOC 2 Type I and Type II?

Type I is a point-in-time assessment that evaluates whether controls are suitably designed. Type II evaluates both the design and operating effectiveness of controls over a period, typically 6-12 months. Type II provides significantly stronger assurance and is what most enterprise customers require.

How long does SOC 2 take?

Type I typically takes 2-4 months from readiness through report delivery. Type II requires a 6-12 month observation period during which controls must operate effectively, plus audit and reporting time. Total timeline from project start is typically 9-15 months for a first-time Type II report.

How much does SOC 2 cost?

SOC 2 costs typically range from USD 20,000-80,000 depending on scope, report type (Type I vs Type II), organization complexity, and the CPA firm selected. Additional costs may include readiness consulting, GRC tooling, and internal resource allocation.

Is SOC 2 the same as ISO 27001?

No. SOC 2 is a US attestation report issued by a CPA firm, primarily recognized in North America. ISO 27001 is an international certification issued by accredited certification bodies with global recognition. Both address information security but differ in approach, output format, and market recognition. Many organizations pursue both.

Which Trust Services Criteria do I need?

Security (Common Criteria) is mandatory for every SOC 2 report. The other four criteria — Availability, Processing Integrity, Confidentiality, and Privacy — are chosen based on the services you provide and what your customers require. Most organizations start with Security plus Availability.
