To protect the security of the computer, in addition to anti-virus software, another means is a firewall. The firewall has two main purposes: 1) To resist the attack of the external network on the local computer; 2) To effectively control the access of the local program to the Internet. It's a pity that Windows' built-in firewall has a single function and poor usability, so there are a large number of third-party firewall programs. Of course, all third-party firewalls implement corresponding functions based on the operating mechanism of Windows' built-in firewall.

The design idea of NetLimiter is to completely and reasonably control, distribute the Internet traffic/bandwith for various network software, so as to make sure they can run smoothly at the same time without disturbing each other. While in AppNee's view, its powerful and perfect Internet connection monitoring & statistics functions (with very comprehensive data) are really helpful to system security and computer efficiency management.
