When it comes to data security and compliance, ISO 27001 and SOC 2 are two of the most recognized frameworks. While they serve similar purposes—ensuring data protection and risk management—they cater to different audiences and have distinct approaches.
ISO 27001 vs SOC 2: Key Differences
| Feature | ISO 27001 | SOC 2 |
|---|---|---|
| Purpose | Establish a formal Information Security Management System (ISMS). | Ensures service providers securely manage data to protect customer privacy. |
| Applicability | Global standard for any organization. | Commonly used in the U.S. for SaaS and cloud service providers. |
| Certification Body | Requires certification by an accredited body. | AICPA governs SOC 2, and audits are performed by CPA firms. |
| Focus Areas | Risk management, continuous improvement, security controls. | Security, availability, processing integrity, confidentiality, and privacy. |
| Assessment Type | Certification-based audit. | Type 1 (point-in-time) or Type 2 (ongoing) audit. |
ISO 27001 is a globally accepted security management standard, while SOC 2 is an attestation report that proves compliance with trust service criteria.
