What people say about us…

We tried to find a supplier who understood our requirements and would work with us to help achieve our security standards. This partner we found in Libra Esva.
Libra Esva helps us to facilitate easy email security management throughout our networks.
The system is easy to administrate without any cost intensive long-term training and it’s working exactly as we imagin.

Norbert StegmannPhoenix Mecano Group

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.

I learned from many years using data programs that a program is not better than the people who stand behind and support it. My experience with Libra as a company is excellent, so is the spam filter they stay behind. They manage my Libra ESVA spam filter and also my not understanding computer problems. They have reasonable prices and to cooperate with them is a win win satiation. They deliver more value to us. Thanks …

I needed a simple solution that would work well and be cost effective for all of my customers. Libra ESVA was installed in minutes. It is great that I can offer this additional service and protection to my customers so quickly and easily.The deciding factor was the ease with which Libra ESVA could be deployed and managed. We really needed a set-and-forget type product that wouldn’t place too much of a drain on our IT department’s time.
