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 focuses on managing personally identifiable information (PII) lifecycle for controllers and processors, using a risk-based PDCA (Plan-Do-Check-Act) approach aligned with global privacy laws like GDPR.
Key Components
- Clauses 4–10 extend management system structure for privacy.
- Annex A (controllers): lawful basis, data subject rights, DPIAs.
- Annex B (processors): contracts, sub-processors, assistance.
- Mappings to ISO 27001/27002, GDPR (Annex D).
- Certification via accredited bodies, 3-year cycle with surveillance audits.
Why Organizations Use It
Reduces regulatory risks, fines; enables procurement differentiation; builds trust via auditable evidence. Harmonizes multi-jurisdiction compliance; lowers breach impacts; strategic for cloud/SaaS.
Implementation Overview
Phased: scope/gap analysis, design controls, operate processes, validate. Applies to all PII-handling orgs; 6–18 months typical. Requires PII inventory, training, vendor management, internal audits.
