  • Reduce the risk of data breaches or data misused from cloud-based storage and processing.
  • Provide operation efficiencies and accountabilities throughout an organisation.

What are the benefits of ISO 27018?

ISO 27018 is a code of practice based on ISO IEC 27018:2019, which outlines information technology security techniques code for public cloud service customers. It inspires trust in your business, reassuring customers and stakeholders that personal data and information is protected. The cloud provides numerous benefits, including cost savings, flexibility, and mobile access to information. However, sensitive personally identifiable information (PII), such as medical records, financial information, and digital fingerprints, can be stored and processed on cloud-based services, making it crucial to follow the best practices for protection.
