NetDefender is a simple software program which was developed in order to aid people in cutting off all network traffic, scanning an IP range and blocking the ping command.
Surprise-free setup and clean interface
The installation process is a piece of cake and does not offer to add any products that are not actually vital for the app to work fully. Once you are done with it, you come across a simple and straightforward interface, as it is comprised of a menu bar, several buttons and a list of all rules currently registered. Both power and novice users can find their way around it, without facing any kind of difficulties.
Block traffic and view processes trying to connect to the network
First and foremost, this tool enables you to block or allow all incoming and outgoing traffic, as well as the ping command. Moreover, you can scan a single port or range, so as to view their status, and show a list of all apps currently trying to communicate with the outside network.
Add and manage rules
In addition to that, you should know it is possible create, edit or delete rules with just a few clicks. To be more precise, you can deny or allow access to a specified IP address. As stated above, rules are displayed in the main window, along with information such as source and destination IP, port and mask, as well as the protocol used (TCP, ICMP, UDP).
To wrap it up, NetDefender is a pretty useful piece of software, which acts as free firewall. The interface is suitable to all user categories, the response time is quite good and the computer’s performance is not going to be hampered. Nevertheless, you should know it does not always work properly, some features failing to open more than once.
