In today’s digital era, data breaches and cyber threats have become critical concerns across industries, from fintech and e-commerce to healthcare and cloud service providers. As a result, organizations are under pressure not only to secure their systems but also to prove their commitment to information security to clients, regulators, and partners. Two of the most recognized frameworks for managing data security are ISO/IEC 27001 and SOC 2. But which one is right for your organization? In this article, we’ll help you understand the key differences, similarities, and considerations when choosing between the two. Or, in some cases—why you might need both.
What Is ISO/IEC 27001?
ISO/IEC 27001 is an international standard published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It provides a framework for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). The goal is to help organizations systematically manage sensitive data, reduce information security risks, and ensure legal, regulatory, and contractual compliance. ISO/IEC 27001 certification is globally recognized and applies to organizations of all types and sizes.What Is SOC 2?
SOC 2 is a security framework that specifies how organizations should protect customer data from unauthorized access, security incidents, and other vulnerabilities. The American Institute of Certified Public Accountants (AICPA) developed SOC 2 around five Trust Services Criteria:- Security (mandatory)
- Availability
- Processing Integrity
- Confidentiality
- Privacy
- SOC 2 Type I evaluates the design of controls at a specific point in time.
- SOC 2 Type II evaluates the operational effectiveness of those controls over a period (usually 3–12 months).
