Communication as a Service

In today’s as-a-Service world, things like e-mail or calendars are part of the infrastructure. Regardless of the interface to the user, other services and applications must be able to access this data in a standardized and reliable way.

We see this interoperability and the resulting interchangeability as an important contribution to digital sovereignty.
