ISO 27001

ISO 27001 is an international standard for information security management systems (ISMS), providing a systematic approach to managing sensitive company information.

ISO/IEC 27001 is the world's most recognized international standard for information security management. It provides a framework for establishing, implementing, maintaining, and continually improving an ISMS.

The standard follows a risk-based approach: 1. Context: Understanding your organization and stakeholder needs 2. Leadership: Management commitment and security policy 3. Planning: Risk assessment and treatment plans 4. Support: Resources, competence, awareness, documentation 5. Operation: Implementing risk treatment and security controls 6. Performance evaluation: Monitoring, measurement, internal audits 7. Improvement: Corrective actions and continual improvement

ISO 27001:2022 includes 93 controls across four themes: Organizational, People, Physical, and Technological.

Certification process: - Stage 1: Documentation review - Stage 2: Implementation audit - Surveillance audits: Annual - Re-certification: Every 3 years

Why It Matters

ISO 27001 is the gold standard for information security worldwide. While SOC 2 dominates in North America, ISO 27001 is the de facto requirement for doing business internationally. Certification demonstrates a systematic, risk-based approach to security that satisfies regulators, enterprise buyers, and partners across all industries. The 3-year certification cycle also provides ongoing assurance compared to point-in-time assessments.
