From its inception, A1 Digital pursued a strategy of strategic investments to build a product portfolio comprising critical digital infrastructure elements: IoT, Connectivity, Cloud, Security, and Managed Services. This approach allowed the company to rapidly expand its capabilities and market presence. A key milestone was the establishment of Exoscale, a sovereign European cloud platform with data centers in Switzerland, Austria, Germany, and CEE countries.

One notable deployment is the GA-Lotse platform for the Frankfurt am Main Public Health Office, which uses Exoscale to ensure secure and sovereign cloud operations.
