VivaBlock is a complete email server, security, plug and play solution.
-
It is licensed per unit and not per user.
-
The spam firewall blocks at source based on business rules and not analysis of the emails’ content, making it greater than 90% effective. This method also means it cannot generate false positives.
-
The firewall is also unique in identifying new spam sources twice as fast as the traditional real-time block lists (RBLs). More than 400 new spam sources per second can be added in real-time.
-
The VivaBlock appliances form a server community connected via the central license monitoring hub and the spam blocking improves as each device shares its blocking information.
-
VivaBlock is Self healing. Every 24 hours the appliance automatically does a complete self-test and rebuilds its database before rebooting, so you have a fresh system every day.
