It provides requirements and guidance for managing personally identifiable information (PII) throughout its lifecycle, emphasizing accountability and risk management.

    • Annex A (PII controllers) and Annex B (PII processors) with privacy-specific controls
    • Mappings to GDPR (Annex D) and other standards
    • Certification via accredited bodies with 3-year cycles and surveillance audits

    Why Organizations Use It

    • Demonstrates compliance with global privacy laws like GDPR, reducing fines
    • Enhances trust, competitive edge in procurement, and operational efficiency
    • Manages PII risks, minimizes breaches, and supports vendor oversight

    • Phased: discover/scope, design/plan, implement/operate, validate/improve
    • Applies to all PII-handling organizations; integrates with existing ISMS
    • Involves PII inventory, DPIAs, DSR processes, training; typical 6-12 months to certification (178 words)
