Rilasciata la nuova versione di Libra ESVA, la 2.0.1.

Libra Srl proposes two different solutions for the protection of your electronic mail. One solution is outsourcing to a dedicated server at a Libra data center, or a virtual appliance to be installed at the client’s location.

The outsourcing solution, (Online Protection) foresees the use of a virtual machine server dedicated to ESVA and utilized exclusively by the client, certified at the Libra Srl data center (Cluster VMware VSphere 4), which ensures continuous service without charging the client for technical interventions.

"We were impressed with Libra Esva as it delivered excellent anti-spam performance in our live tests. The software is very easy to deploy and configure and although we had some criticisms these are likely to be rectified in future versions. Libra’s low prices also make ESVA a worthy choice for SMBs looking to virtualise their network security services."
