Blocking websites from certain users

Posted on 2007-08-09

My router does this in a very limited fashion. I would like to control which sites certain users are able to visit at various hours of the day. Does anyone know of any hardware that can control access for at least 50 computers? Thanks.

    The best bet is to install a proxy server. This will allow you to control access, monitor activity, and automatically cache frequently used pages for quicker access. Several of Proxy server apps can be found at the following sites, but there are many more available.

    You can also control access using Internet Explorer and do a mass deployment using the IEAK (Internet Explorer Administration Kit), but it is rather a nuisance to update.

    Are there no hardware solutions then?

    Many routers have some basic filtering, the mid and upper level routers often offer add on web filtering services, such as WatchGuard's WebBlocker service:

    Then there are Web filtering dedicated appliances such as:

    However, using a PC and Proxy server software, is usually the most affordable, and gives you good control.

    How about a Barracuda appliance? I have installed them and they work GREAT!

    I'm using a couple Fortigate 100A's ( for 50ish users at each site and a site to site VPN. Performs well under these loads. You can configure time schedules, allowed url lists, blocked url lists, for groups and individual systems (users and/or IP) based on internal groups or AD integration - all the standard firewall functions then some.  Added perks of antivirus, antispam, IPS at the perimeter for a yearly support/services subscription all for a good price point. Any Cisco ASA appiance will also do what you want, but for more $$. I've used the Fortigates for several months now and am pleased with them so far.

    Just to mention another one that hasn't been mentioned... we use SonicWALLs extensively for many sites and this functionality is available as well as a host of other great features... the smallest Pro device should be adequate for your needs...
