- Built on real-world practices; PeopleCert certifications (Foundation to Strategic Leader).
Why Organizations Use It
Drives cost savings, 20% faster resolutions, 87% global adoption, cyber risk mitigation ($3M+ breaches), ROI up to 38:1, enhanced satisfaction, common language for collaboration, digital transformation edge, career boosts.
Implementation Overview
Phased via 10-step roadmap: preparation, assessment, design, integration, training. Tailored for enterprises/SMEs, all sectors; voluntary PeopleCert audits. Start small, iterate, customize for 12-18 months typical rollout.
ISO 27701 Details
What It Is
ISO/IEC 27701:2025 is the international standard for establishing, implementing, maintaining, and improving a Privacy Information Management System (PIMS). It extends ISO 27001 with privacy-specific requirements for PII controllers and processors, using a risk-based, PDCA (Plan-Do-Check-Act) management system approach to manage privacy risks.
Key Components
- Clauses 4–10 mirror ISO 27001, extended for privacy (context, leadership, planning, support, operation, evaluation, improvement).
- Annex A (controllers): controls for lawful basis, transparency, data subject rights, retention.
- Annex B (processors): contractual obligations, sub-processor management.
- Mappings to GDPR (Annex D), ISO 27002; ~100 privacy controls.
- Certification via accredited bodies, 3-year cycle with surveillance audits.
Why Organizations Use It
- Demonstrates accountability for global privacy laws (GDPR, LGPD, POPIA).
- Reduces risks from breaches, fines; builds supply-chain trust.
- Enables procurement differentiation, regulatory evidence.
Implementation Overview
- Phased: gap analysis, risk assessment, controls, audits.
- Applies to all PII-processing orgs; faster with existing ISMS.
- Involves RoPA, DSAR processes, training, vendor governance. (178 words)
