Overview

CompuGroup Medical (CGM) is one of the world's leading companies in the field of e-health. It develops and markets innovative, platform-based solutions for hospitals, rehabilitation facilities, and nursing homes.

Challenge

Following the acquisition of a medium-sized German company in 2023, CGM faced a critical challenge: The previous IT service provider was unable to deliver the project in a market-ready state—neither meeting the required quality standards nor providing the necessary level of information security, nor within a reliable timeframe.

By the time our team came on board, the project had already been stalled by the previous provider for over a year.

Working with sensitive patient data always requires the highest standards of compliance and security. Our goal was to build a secure, scalable hybrid cloud infrastructure capable of hosting the patient portal and its associated services.

Our Solution

As soon as we took over the delayed project, we launched a complete overhaul of the cloud infrastructure from the ground up. Despite the complexity, the team delivered the solution in just six months —and with fewer staff than the previous company.

The new system was deployed on the T Cloud Public. Since the customer operates in the healthcare sector, security was a top priority. We therefore implemented a BSI C5-compliant architecture that meets the highest German federal standards for cloud security.

To support the customer’s future, growing needs, the platform was designed for automatic scaling, ensuring optimal performance even during peak traffic on the patient portal.

Business Impact

We are proud to report that our client’s infrastructure now reliably delivers healthcare IT solutions. Healthcare providers no longer need to worry about security or compliance when working with our client.

Hospital staff, patients, and administrative teams all benefit from a seamless experience. Patients report improved communication and efficiency throughout their entire treatment process. Now everyone can focus on receiving the best possible care.

Following CompuGroup Medical’s (CGM) acquisition of a medium‑sized German company in 2023, we determined that the existing IT service provider was unable to bring the project to market‑ready status with high quality, high information security standards, and within a reliable timeframe. We then commissioned iits‑consulting to completely rebuild this infrastructure using the OpenTelekomCloud. Within just six months, iits‑consulting not only successfully completed the project but also helped us establish a highly secure, BSI C5-compliant infrastructure that specifically addresses client isolation and complex connections to the hospitals’ system networks from the cloud. iits‑consulting’s ability to develop a complex and secure cloud environment under tight deadlines while meeting the highest technical and security standards has made them a valuable partner. I recommend iits‑consulting for demanding IT projects, particularly in areas that require a high level of security and technical excellence.
