I like the ease of use, the ability to customize it to my needs, and the ability to monitor traffic and block malicious sites. I dislike the fact that sometimes it does not work as intended (if you have more than one instance of the software, you have to go into the settings and manually change the IP addresses). I have found that this software is very easy to use and is very effective in blocking malicious sites and traffic. It is very easy to setup and configure. I use it primarily to block malicious sites and traffic from my employees.
