More than your average web filter.
It's an uncomfortable situation for the network administrator:
You sift through web logs one Friday afternoon (because finally the network
is running smoothly enough to allow you time to play catch-up), and you
discover that John Q User has been visiting illicit, immoral, illegal
and most definitely unproductive Web sites during working hours. You dust
off your Internet Usage Policy and Procedure handbook to figure out what
should be done. In the end you wind up with a chagrinned employee, an
irate boss and an unhappy network administrator who now has the task of
putting out an e-mail to remind everyone of the surfing policies.
Websense Enterprise 4.3 removes the need for all human intervention from
the above scenario. Utilizing a database of more than 2.4 million sites,
it works with an existing “integration provider” such as Microsoft Internet
Security and Accelerator Server to filter URLs and to prohibit or allow
sites based on more than 75 pre-defined categories, such as adult material,
gambling, and health.
I chose to incorporate Websense Enterprise into an installation of Microsoft
Internet Security and Accelerator server. Websense Enterprise installed
without incident on my ISA server. After putting in the required registration
key and downloading the 25M database, I loaded up my browser ready to
be deterred from all of the illicit sites I was poised to test. I knew
from the exceptional documentation that the global policy would immediately
start filtering and blocking Web sites. I went straight to www.sex.com
and was surprised to see the screen-full of pictures that I'm glad my
boss didn't see. Forty-five minutes later, I decided to restart the Web
Proxy service, which I finally realized I’d have to do to reload the ISAPI
filter. I missed the part of the documentation that mentioned the need to do this; it would have been nice to have a dialog box during the installation mention this requirement. After restarting the Web Proxy service,
Websense jumped into action and presented me with a courteous webpage
informing me that "sex" was blocked. As I could no longer view illicit
material, I figured I would book a flight to Mexico. Websense saw through
my ploy and informed me that making travel arrangements, though permitted
in this profile, was being monitored by Websense. So then I decided I
would look for another job and was gracefully declined by the now-familiar
Websense Web page. I was very impressed with how many sites Websense was
| Websense Enterprise Manager includes a wide selection
of pre-defined filter categories. (Click image to view larger version.)
Websense goes way beyond basic filtering and offers many advanced features.
One of those features is the use of custom policies to limit the viewing
time by category with a built-in time quota system. All in all Websense
was very easy to install and implement and did everything advertised.
The extended feature set is well worth the yearly cost per user of roughly
$15 per year. After I was done testing, I immediately recommended to my
boss that we acquire this service because, although we have a written
policy for Internet usage in place, it would be nice to let Websense handle
the ugly work when a user goes astray.
