The best-known and probably most widely used collaboration tool is packed with innovative features. But GDPR compliance is crumbling. Time to look for a Microsoft Teams alternative.

The Microsoft Teams alternative for fast and secure cross-company communication


With our data protection and data security concept, we ensure absolute GDPR compliance, offer you the best possible data sovereignty, and meet all compliance requirements for the telecommunications sector.

Cloud or Self-Hosting

With a server location based in Germany, we ensure the secure cloud alternative for cloud-based work. In case of demand for Microsoft Teams on-premise, we offer the option of self-hosting deployment on your own server.

Easy to use

The simpler the handling of the interface, the higher the user acceptance. We strive for ease of use for all users – office colleagues and mobile employees – despite all the complexity of certain work steps and processes.

Open API

The automation of collaborative work processes is constantly being accelerated. With the help of open APIs, third-party tools and systems can be directly linked and integrated. As the range of functions increases, so does the productivity of employees.

Why rely on a Microsoft Teams alternative?

The main requirement is security

Many requirements can be placed on a collaboration tool. When it comes to secure communication, it is advisable to use a GDPR-compliant business messenger.

Avoid CLOUD Act access through US companies

The CLOUD Act allows US authorities to access data from US IT companies and cloud providers. In the case of Microsoft Teams, the tool itself is GDPR-compliant, but access to the data stored in the data center cannot be completely prevented.

The Microsoft Teams alternative for all common communication channels

MS Teams is known for the platform concept that couples chat, video calling, notes and attachments. In conjunction with the Microsoft Office 365 suite, it even enables parallel work in Office documents, which benefits project teams in particular. If cross-company communication comes to the fore, an employee app should be provided for all employee communication.
