I like that it's easy to use, secure from malware etc., as well have some useful features such as being able of blocking certain protocols or types if we want too! Very good product for an affordable price (it works great with other security products).
It could be better in terms of usability/user interface but nothing bad at all so far i've seen about this software!! Perfect solution since you can block any unallowed access without having problems when working over wifi networks where there is alot more traffic than usual internet sources.
