SOC 2 vs ISO 27001: What’s the Difference and Which Standard Do You Need?

• SOC 2 and ISO 27001 are leading security frameworks that help organizations demonstrate strong data protection and compliance, with an 80% overlap in their criteria.
• SOC 2 is more flexible and widely recognized in the US, while ISO 27001 is internationally respected, focusing on building a comprehensive information security management system (ISMS).
• Tools like a basic ISO 27001 mapping spreadsheet can help organizations efficiently align controls across both frameworks, saving time and resources during compliance efforts.

SOC 2 and ISO 27001 are the most recognized frameworks for information security compliance. SOC 2, developed by the AICPA, focuses on protecting customer data through five Trust Services Criteria: Security, Availability, Confidentiality, Privacy, and Processing Integrity. It is particularly popular among US-based companies, offering flexibility in selecting applicable criteria. ISO 27001, on the other hand, is an internationally recognized standard for establishing and maintaining an Information Security Management System (ISMS). With its 93 mandatory controls under Annex A, ISO 27001 provides a structured approach to securing sensitive information, especially appealing to global organizations and European markets.

While both frameworks require rigorous third-party audits, they differ in structure and scope. SOC 2 audits often focus on a specific point in time (Type I) or over a defined period (Type II), making them a quicker option for companies looking to validate operational effectiveness. ISO 27001 involves a two-stage certification process with a more prescriptive approach, requiring detailed documentation and continuous improvement of the ISMS. Both audits demand significant time, effort, and cost, but ISO 27001 certifications typically require more extensive documentation and have a higher price tag. Despite these differences, many companies pursue both to cover diverse customer requirements and strengthen their global compliance posture.

A valuable resource for organizations navigating these standards is a ISO 27001 vs. SOC 2 mapping tool, which highlights an 80% overlap between the two frameworks. Provided by the AICPA, this mapping spreadsheet allows companies to streamline their compliance processes by aligning overlapping controls, reducing redundancy in documentation and audits. This efficiency is particularly beneficial for growing companies aiming to meet both US and international customer expectations. Leveraging tools like this, combined with compliance automation platforms, helps accelerate audit readiness and maintain ongoing compliance with both standards.

Choosing between SOC 2 and ISO 27001 depends mainly on a company’s target market, industry standards, and long-term business goals. US-based SaaS providers often prioritize SOC 2 to meet local customer demands, while global enterprises favor ISO 27001 for its international credibility. However, many organizations find that pursuing both certifications strengthens customer trust, expands market opportunities, and provides a competitive advantage. By utilizing mapping tools and expert support, companies can navigate the complexities of both frameworks efficiently, ensuring comprehensive and cost-effective compliance.
