Netfee Enterprise (32 bit) provides a way for Communicating with external departments. However, they have to face many administration problems such as how to control the time usage, traffic usage, and websites visited. Integrated with popular firewall systems (ISA server, Winroute, Winproxy), Netfee can do Usage Analysis, Reporting, and Performance management. It is a network software solution for managing Internet access. It consists of an analysis module, charge module, and reporting module. Netfee analyses the firewall's log files, then write the result into database. The administrator can monitor the Internet usage (Bytes, Time, and URLs) of every user at real time by querying the database. And base on the usage of Bytes and time, Netfee can calculate the user's fee to pay. In addition, Netfee can classify the URLs into categories by content.
