ISO 27701 Details
What It Is
ISO/IEC 27701:2025 is an international standard providing requirements and guidance for a Privacy Information Management System (PIMS). It extends ISO/IEC 27001 for privacy governance, focusing on managing risks associated with personally identifiable information (PII) processing.

- Annex B (processors): contracts, confidentiality, sub-processors.
- Mappings to GDPR, ISO 27002; ~50 privacy-specific controls.
- Certification via accredited bodies, 3-year cycle with surveillance audits.
Why Organizations Use It
- Demonstrates accountability for GDPR/POPIA compliance.
- Reduces privacy risks, enhances supply-chain trust.
- Provides audit-ready evidence, competitive differentiation.
Implementation Overview
- Phased: gap analysis, risk assessment, controls, audits.
- Suits all sizes/industries processing PII; integrates with ISMS.
- Typical 6-12 months; requires documentation, training, RoPA, DSAR processes.
