SOC 2 vs ISO 27001: Which Security Certification Is Right?

SOC 2 and ISO 27001 are the two most common security certifications requested by enterprise customers. Understanding the differences will help you invest in the right certification for your business.

SOC 2 and ISO 27001 are both respected security frameworks that demonstrate to customers, partners, and regulators that your organization takes information security seriously. But they serve different purposes and are recognized differently in different markets.

SOC 2: The US Enterprise Standard

SOC 2 (Service Organization Control 2) is an attestation report issued by a CPA firm verifying that your security controls meet the AICPA's Trust Services Criteria. It is the de facto standard for SaaS companies and service providers selling to US enterprise customers. SOC 2 Type I attests controls are designed correctly at a point in time; SOC 2 Type II attests controls operated effectively over 6-12 months — what most enterprise customers require. Timeline: 6-12 months. Cost: $30,000–$100,000+. Best for: US-focused B2B SaaS companies.

ISO 27001: The International Standard

ISO 27001 is an internationally recognized standard for Information Security Management Systems. It carries weight globally — particularly in Europe, Asia-Pacific, and government contracting. Timeline: 9-18 months. Cost: $30,000–$150,000+. Best for: international expansion, European customers, government contracting.

Which Should You Pursue?

Choose SOC 2 if you sell primarily to US enterprise customers or you are a SaaS company.

Choose ISO 27001 if you have international customers, sell to European companies, or need a comprehensive ISMS.

Choose both if you are an international SaaS company targeting enterprise customers globally.
