The platform
The complete workplace. Sovereignly operated.
Souvera Workspace bundles all everyday work tools in one environment – from email and office to video conferencing. Every module is deeply integrated, every instance strictly separated from other customers.
Modules

All modules share login, search, contacts and notifications – so the workspace feels like a single product, not a collection of tools.

Architecture
Three layers. All exclusively yours.
Souvera deliberately avoids shared infrastructure: what belongs to your workspace belongs only to your workspace.
Your workspace
Your team's work environment: Mail, Files, Desk, Link, Calendar – one interface, one login.
Your own mail server
Every workspace receives a dedicated mail server with modern delivery infrastructure – exclusively for your domain.
Your security layer
Upstream spam and virus protection with quarantine plus DMARC reputation monitoring of your domain.
All three layers are provisioned and operated separately per customer. There are no shared mailbox systems – what happens in your workspace stays in your workspace.
Migration made easy
From your old provider to Souvera – without data loss
The integrated mail importer fetches your existing emails directly from your previous provider. No exports, no workarounds, no downtime.
- Direct IMAP import from virtually any provider – including all folders
- Keeps running in the background, even if you close the window
- Your old provider's credentials are discarded immediately after the start and never stored
- Files, calendars and contacts can also be migrated via open standards
