WFilter is an internet monitoring and filtering software program that can help organizations to monitor and manage all internet behaviors on their networks. You only need to install WFilter in one computer to monitor and manage your whole network.

WFilter is a network sniffer. All functions are based on network packets analysing.

WFilter is a content-based management tool. WFilter intercepts, records and monitors Internet behaviors of users on a network, for the purpose of ensuring policy compliance, or measurement on job performance in an organization.

WFilter is not a firewall. Firewalls generally work on the gateway, and provide access control based on IP and ports. WFilter is a sniffer, which doesn't need to install on the gateway. It is content based instead of IP/ports based.

WFilter is not a trojan program. It doesn't need to install any trojan programs on client computers. So it can not support screen monitoring, USB forbiding and keystroke recording.
