I liked the vulnerability scanning and patch management feature of GFI Languard. It is a must-have tool for patch management. Scanning is fast and accurate. The vulnerability list is comprehensive. The software is easy to install and configure. Report generated is good and very illustrative. Over all it is a powerful tool for system and network management.

I think the thing I like best, is the ability to be able to manage the system with ease. They designed the GUI to be easy to read, use and understand.

Kerio Control is one of the best intrusion detection and prevention system. The main reason why I love using it is because of its simplicity and ease of configuration. You can administer it from anywhere and anytime from your desktop or remotely from a tablet device. It manages bandwidth via prioritization and traffic monitoring, Internet link load balancing, and limiting access to streaming video and peer-to-peer networks. It helps to preserve the integrity of your network by preventing viruses and exploits, configuration-free VPN clients, create both in and outbound traffic policies, protect your servers, and advanced networking routing.
