ISO/IEC 27018:2025 - Privacy in Cloud Environments

ISO/IEC 27018 helps organisations protect personal data in the cloud, and we help you design, implement, and maintain privacy controls that meet regulatory and customer expectations.

What is ISO/IEC 27018:2025?

ISO/IEC 27018 is the international standard for protecting personal data in public cloud services. It provides a structured framework for managing privacy risks, applying cloud‑specific controls, and demonstrating responsible handling of customer PII.

The standard requires organizations to balance regulatory and contractual privacy obligations with practical cloud controls. ISO/IEC 27018 emphasises transparent processing, data subject protections, and controls that address identified privacy risks
