Enreach receives internationally recognised audit attestation for SwyxON

8 Sep 2025

Independent audit confirms cloud security according to BSI C5 criteria catalogue

Enreach, a leading provider of smart contact solutions for business customers, meets one of the highest standards for cloud security in Europe for its SwyxON communications solution. The C5 catalogue sets out clear criteria for the highest cloud security and compliance standards. 

Enreach has achieved a key milestone in cloud security with the successful completion of the BSI C5 audit (Type 1) for its SwyxON communications solution. Issued by Germany's Federal Office for Information Security (BSI), the C5 (Cloud Computing Compliance Criteria Catalogue) is internationally recognised and aligns with globally accepted security frameworks such as ISO/IEC 27001. It serves as a valuable benchmark for organisations across Europe and beyond that require transparent, verifiable standards for cloud security and compliance. 

Enreach has fully met the strict criteria for cloud solutions defined by the BSI with SwyxON, demonstrating its commitment to security, data privacy and compliance in the cloud. Enreach thus provides customers with the basis for qualified risk management and shows that its Swyx cloud solution is also suitable for companies with special security requirements and strict regulations. 

”The C5 audit confirmed that our SwyxON cloud solution meets the highest standards in data protection, IT security, and compliance. This independent validation is not only a strong signal to our customers and partners that Enreach delivers innovative and secure solutions, but it is also a necessary factor for security-sensitive industries such as government, finance, insurance, and healthcare. For these sectors, trust is built on transparency and verified security. With SwyxON, they can rely on a cloud offering that has been independently tested, making it easier for them to adopt modern cloud technologies with confidence,“ explains Enreach Chief Product Officer Martin Claßen. 

With the successful C5 audit for SwyxON, Enreach once again underlines its commitment to providing companies with secure and powerful cloud communication solutions. This enables Enreach partners to address customer groups that have particularly high requirements for compliance, data protection and security, and to support their digital transformation in the long term.
