Like any good firewall, VisNetic Firewall lets you control network activities by blocking or allowing certain ports, protocols, and IP ranges. The program distinguishes itself with its handy interface. The firewall is quite easy to set up and automatically generates a default list of allowed transfers. Creating new rules is simple. The program also offers some professional features; you can control instances of VisNetic Firewall on other machines, for example, and lock the firewall with a password. However, the program lacks e-mail notification and alarms that would let you react immediately to threats. It consumes about 5MB of memory, a bit much for a program that constantly runs in the background. Because it doesn't explain how dangerous detected network activities are, beginners might want to steer clear. VisNetic Firewall suits knowledgeable users, especially those in small businesses or with home networks.
