Netmaster uses 'sniffer technology', it allows you to track individual Internet use within your organisation. You can see how much time is being spent on business and how much time is being spent on personal use from the Web site report generator. All Web site browsing is classed in to a wide range of categories from Adult to Education and shows the user responsible for downloading the page and the computer used. Netmaster can BLOCK Web sites from users via Category, Domain, or IP Blocking just by being on the LAN and without changes to your network users computers.
