BSI C5 (Cloud Computing Compliance Controls Catalogue)

Companies are increasingly using cloud services to streamline their business processes. BSI C5 (Cloud Computing Compliance Controls Catalogue), developed by the Federal Office for Information Security (BSI), provides a reliable foundation for security and transparency. The standard defines how security measures should be implemented in the cloud, how risks should be managed, and how anti-fraud mechanisms are integrated. The BSI C5 report serves as proof that appropriate control measures are in place and is an important tool for mitigating risks when using cloud services. It ensures that cloud providers adhere to robust security standards, which are especially critical in sensitive sectors such as healthcare and finance.

BSI C5or ISO 27001 & SOC 2

BSI C5: Security and Transparency

BSI C5 enables cloud providers to demonstrate their security controls through independent audits. The standard systematically evaluates the protective measures in place for cloud services and promotes transparency for customers.

ISO 27001 & SOC 2: Data Protection and Information Security

ISO 27001 and SOC 2 focus more broadly on general security and data protection requirements across all industries. Both standards complement BSI C5 and can be applied in parallel.
