SOC 2 vs. ISO 27001: Which One Should You Get First?
Both certifications demonstrate information security commitment, but they serve different audiences and markets. The answer depends on who you are selling to.
SOC 2 and ISO 27001 are the two most common information security frameworks that software companies and service providers pursue. They're often conflated, but they serve different purposes and different markets.
The Core Difference
**SOC 2** is a US-origin attestation report produced by a CPA firm. It's not a certification — it's an audit report. The Trust Service Criteria (Security, Availability, Confidentiality, Processing Integrity, Privacy) were developed by the AICPA. SOC 2 is primarily recognized in North America.
**ISO 27001** is an international standard — the leading global information security management system (ISMS) standard. It results in a certificate issued by an accredited certification body. ISO 27001 is recognized globally, particularly in Europe, the Middle East, Asia-Pacific, and with enterprise buyers.
The Market Question
**Choose SOC 2 first if:** - Your primary market is North America - Your buyers are US enterprise software buyers or SaaS procurement teams - You are selling to financial services, healthcare, or government contractors in the US - Your prospective customers are asking for a SOC 2 report in procurement questionnaires
**Choose ISO 27001 first if:** - You are selling to European enterprise buyers or government entities - You are pursuing DORA or NIS2 compliance (ISO 27001 is referenced in both) - Your buyers include large multinationals who prefer international standards - You are operating in healthcare (EU MDR environment) or financial services outside the US
Can You Do Both?
Yes — and many companies do. ISO 27001 and SOC 2 have significant control overlap. An organization with a mature ISO 27001 ISMS has approximately 60-70% of the evidence needed for a SOC 2 audit already collected. ComplianceGuard maps controls across both frameworks and identifies shared evidence opportunities, reducing the cost of dual certification significantly.
