Microsoft 365 Alternative · Made in Germany
The Microsoft 365 alternative that keeps your data
Microsoft 365 is powerful – but your data is subject to the US CLOUD Act. Souvera Workspace offers the same functionality as a GDPR-compliant alternative from Germany: email, online office, files and video conferencing in one platform, operated in German data centers.
