SOC 2 and ISO 27001 are two of the most recognized information security frameworks. Both help organizations protect data, but they serve slightly different purposes.

SOC 2 Overview

  • Developed by AICPA (U.S.-based).
  • Focuses on five Trust Services Criteria (security, availability, processing integrity, confidentiality, privacy).
  • Widely requested in North America, especially by SaaS companies.

ISO 27001 Overview

  • Developed by the International Organization for Standardization (ISO).
  • Focuses on building an Information Security Management System (ISMS).
  • More global recognition, especially in Europe and Asia.

Key Differences

  • Geography: SOC 2 is more U.S.-centric; ISO 27001 is international.
  • Audit Style: SOC 2 = flexible controls, ISO 27001 = structured ISMS.
  • Report Type: SOC 2 results in a detailed audit report; ISO 27001 provides a certification.

Which Should You Choose?

  • If you’re a U.S.-based SaaS company → SOC 2 is usually required.
  • If you serve international clients → ISO 27001 may be more valuable.
  • Some companies pursue both for maximum assurance.

Final Takeaway: The right choice depends on your market, but SOC 2 is essential for SaaS growth in the U.S.
