Souvera Shield
Mail security for users. Reputation for admins.
Souvera Shield protects every inbox with upstream spam and virus filtering – and gives users control over their own quarantine. Administrators additionally get professional reputation management for their own domain.
- Personal quarantine per user
- White & blacklists in user hands
- DMARC reputation monitoring
For end users
Spam control belongs in the user's hands
No waiting for IT: every user manages their own quarantine and their own lists – directly in the workspace.
Overview dashboard
Five counters at a glance: quarantine, whitelist, blacklist plus withheld attachments and viruses – and the new arrivals of the last 24 hours.
Spam quarantine
Review withheld mails via preview (including headers), release or delete – individually or in bulk, with full-text search and CSV export.
File & virus quarantine
View content blocked by the content filter or virus scanner and release it in a controlled manner – if enabled by the administrator.
Personal whitelist
Permanently allow trusted senders or entire domains – every user maintains their own list.
Personal blacklist
Permanently block unwanted senders – without a ticket to IT.
Notifications
Alerts for new quarantine mails, optional daily summary, dashboard widget and results in the unified search.
Mail reputation management: so your mails arrive
The best email is useless if it lands in the recipient's spam folder. Souvera Shield continuously monitors your domain's delivery reputation – fully integrated, clearly presented and without external tools.
Domain setup assistant
Automatically detects your domain, registers it for monitoring with one click and shows the required DNS records (verification & DMARC) directly with a copy button.
DKIM & SPF statistics
Pass rates in traffic-light colors for 7, 30 or 90 days, total volume and top senders – you see instantly whether your authentication runs cleanly.
DMARC aggregate reports
The feedback from major recipient providers, clearly presented: reporting organization, period, DKIM/SPF result and applied policy.
Automated mail test
Every week, an automatic reputation test checks your outgoing mail and assigns a score from 0–10 – can also be triggered manually at any time, with a full history.

How it works
An email's journey through Souvera Shield
Arrival
Every incoming mail first passes the upstream security layer – before it ever reaches your mailbox.
Inspection
Spam scoring, virus scanning and content filtering analyze the message and its attachments.
Quarantine
Suspicious messages are withheld – the recipient is notified.
Your decision
Release, delete or permanently allow/block the sender – the control lies with the user.
Control & compliance
Traceable down to the detail
Shield is built for enterprise use: with a clean permission model and complete logging.
Audit log
Every release, deletion and list change is logged chronologically – exportable for compliance purposes.
Central settings
Enable file and virus quarantine per instance, control notifications and spam thresholds centrally.
Role-based permissions
End-user functions and reputation management are cleanly separated via groups – technically enforced on every endpoint.
Encrypted credentials
All connection data is stored encrypted; central API tokens are managed by the credentials hub in Souvera Central.
Security you can understand.
