With internet access server you have multiple internet connections running simultaneously in your office
with automatic fail-over and load balancing.
Also you can restrict usage of internet on a per-user basis.
For example some staff will be allowed to use only few websites.
The senior staff may be allowed a larger base of websites but will be
restricted for some sites.
The bosses may not be restricted at all.
Also you can have a report of the usage summary with a list of websites each user
has used and also the number of bytes the particular user has consumed.
The web filter is based on Opensource proxy server.
These features are all based on the server, nothing is installed on the users computer so the user cannot tamper with any settings.
