What is the difference between the versions of GFI WebMonitor?
See the GFI WebMonitor features area.
What types of authentication options are available in the standalone version of GFI WebMonitor?
See the documentation page for information on authentication.
How are users counted in GFI WebMonitor?
Licensing is based on users when authentication is enabled or IP addresses if it is not. See http://go.gfi.com/?pageid=webmon_user_count for more information.
How do we configure clients to use GFI WebMonitor as the proxy and how do we prevent them from bypassing it?
The user's Internet browser must be configured to use the GFI WebMonitor server as the proxy to enforce web filtering. With Internet Explorer, this can be configured with Group Policy. With other browsers, it is best to use the port blocking or traffic forwarding option, as described in http://go.gfi.com/?pageid=webmon_portblocking.
