The most important certifications in the cloud sector include international standards such as ISO/IEC 27001, a standard that defines requirements for information security management systems, and ISO/IEC 27017, which specifically describes security measures for cloud services.
In Germany, the BSI C5 criteria catalog and the Trusted Cloud Data Protection Profile (TCDP) are also relevant. They define binding minimum requirements for data and information security that cloud service providers must meet.
There are also various types of certification: While a self-disclosure by the provider is sufficient for some, others, such as the EuroCloud Star Audit or TÜV certificates, are based on external audits and on-site inspections. The main areas audited are data security, risk management, compliance with regulations, encryption and the reliability of all services.
Cloud certifications are very useful because they create transparency and make it easier for users to choose a trustworthy provider. At the same time, they provide companies with legal protection. Nevertheless, they should always be examined critically, as the test procedures and the validity can vary depending on the certificate.
