More secure than Skype for Business.

End-to-end encryption

Element is end-to-end encrypted; even if a server or network is compromised, encrypted data can’t be viewed.

Message security

Messages are decrypted per-device, rather than per-user, to add an extra layer of security.

Cross-signed device verification

Cross-signed device verification guards against man-in-the-middle style attacks.

Fast and simple migration.

Skype for Business Server is approaching End of Life, and it has no on-premise migration path. 

Element is the natural replacement. It offers the same data ownership model, but with the added protection of end-to-end encryption and a complete enterprise messaging and collaboration platform.

Element is helping all types of organisations migrate from Skype for Business.

Our Skype bridging service, in particular, helps large organisations migrate per department or by region. It enables Element and Skype for Business users to message each other, with a native look and feel, without switching apps.

And of course, being Matrix-based, Element also bridges to traditional collaboration and messaging apps such as Microsoft Teams, Slack, WhatsApp and Signal.

A unique Skype for Business replacement.
