Cloud Computing Compliance Controls Catalog (C5) by the Federal Office for Information Security

The German Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik, or BSI) Cloud Computing Compliance Controls Catalog (C5) certification provides companies with a competitive edge, proving that their security protocols are among the most robust and reliable on the market. This certification also helps to demonstrate compliance with any legal or regulatory requirements that may apply to a company’s operations. As a result, it’s an integral part of any comprehensive security program and is essential for companies wanting to protect their data, systems, and reputation.

BSI C5 certification is difficult to obtain due to its stringent requirements and the significant amount of resources required to ensure compliance. Fortunately, we can help make the lengthy certification process more efficient to achieve Germany’s highest level of security compliance. Trust Us to Get You There.

The BSI C5 Process

The German BSI C5 certification is one of the most difficult security certifications to obtain due to its stringency. It requires an extensive audit, testing and assessment of existing information systems as well as new implementations to ensure that they are able to withstand multiple attack scenarios. Furthermore, the German BSI C5 certification involves a lot of manual labor in terms of process analysis, security reviews, and the implementation of additional controls. No matter where you are in your C5 process, 38North can make certification easier. ‌Talk with one of our BSI C5 experts.


BSI sets out criteria for evaluation based on five key areas: system architecture, data management and protection, authentication and authorization, network protection, and system operation. Let 38North take care of the self-evaluation for you in preparation for the audit.


The German BSI C5 certification process is carried out by accredited German BSI auditors. Auditors assess the system’s security levels according to the German standards and guidelines for secure IT systems that have been established by BSI. Additionally, audits require a full examination of the system architecture, as well as a review of networks, protocols and security measures. 38North partners with German BSI auditors who have a long history of expert in-country security services.

Committee Evaluation

BSI reviews the auditor’s findings to determine whether or not German C5 certification can be awarded. 


Finally, German C5 certification is granted upon successful completion of all the previous steps. 

BSI C5 Certification Challenges

Companies must also implement comprehensive policies and procedures to ensure their systems remain secure over time. To pass German BSI C5 certification, companies must demonstrate an exceptionally high level of security protocols that are enforced by regularly conducting ongoing monitoring activities.
