ISO/IEC 27701:2019 is an extension of the ISO/IEC 27001 and ISO/IEC 27002 standards. While ISO 27001 provides a framework for an Information Security Management System (ISMS), ISO 27701 builds on this to include privacy-specific requirements and guidance. Essentially, ISO 27701 provides a structured approach for managing Personally Identifiable Information (PII) and enhancing data privacy practices within an organization.
