C5
Demonstrate secure cloud infrastructure with C5 attestation
A commonly recognized compliance standard for cloud service providers (CSPs) is the Cloud Computing Compliance Criteria Catalogue or C5. Achieving C5 attestation is essential for security-conscious CSPs operating in Germany that want to demonstrate their commitment to security to clients and customers.
By embracing C5, organizations trading in the German market can establish a foundation for secure cloud services, improve their security posture, and gain a competitive edge in the market.

Processing health data using cloud computing?
In the context of the new German regulations for processing health data using cloud computing, cloud service providers must obtain a C5 certificate to demonstrate they meet these stringent security standards.
This ensures that health data is processed securely, aligning with the new legal requirements to protect sensitive information.
Benefits of C5 attestation:
- By complying with the C5 requirements, CSPs can demonstrate a high level of security maturity and gain a competitive advantage in the market.
- Provides a comprehensive framework of standard security controls for CSPs providing cloud services.
- Increased trust with customers through meeting C5’s high security standards.
