Secure Company-wide Collaboration in Microsoft Teams

Decentralized teams and home office work are standard nowadays. Accordingly, the importance of collaboration platforms to support digital communication is constantly increasing. However, especially for companies in the public sector or in highly regulated industries, the use of cloud services such as Microsoft Teams represents a seemingly impassable hurdle.

Laws and regulations such as the GDPR and the US-Cloud Act significantly restrict the storage of data in the cloud. The eperi Gateway encrypts chat messages, channels and files in real-time before they leave your company.

This ensures that you always stay in full control over your data and your way into the cloud is hassle-free.
