Web Filtering is absolute must when it comes to protecting your students and to some extent your staff and network.
Here at the academy we have an unfiltered broadband connection to the Internet via a sponsored connection to EMMAN.
When the academy first opened I decided at the time to install a Bloxx web appliance as I had used Bloxx web appliances on other networks in other schools and colleges.
The appliance had worked well and the Tru-View technology was also very good, anonymising proxies detection worked very well at first but started failing to detect and block our students gaining access to them. This is clearly a big problem on school network! In saying that the support that we got from Bloxx was very good and any problems that we had with any aspect of the appliance other than the webproxy detection was resolved swiftly and effectivly.
Our Web filtering was on a three year contract due to expire in September 2010 so with this in mind we started to look at the whole web filtering market. This may not be the way to go about finding the best solution but I do not like getting involved with products that charge per client or unique user so this ruled out a few products sorry Websense and the like. I hate to say it but if you are dealing with schools and the product you are offering is over 1/2 the cost of our whole MS licensing cost then its not for schools.
This left us with a few good options:-
Bloxx even with the anonymising proxies get round issue was still a good product and they where working on a solution for the anonymising proxies detection. Another slight let down with the the Bloxx appliance is that the reporting is not as good as some of the other products that we tested. The user interface is clean and easy to navigate, blocking and allowing sites is straightforward and the Tru-View web categorisation allows for easy site filtering for multiple groups.
WebCritical this product was available in two forms an appliance and the software to run on your own hardware, this is a good idea as it can cut the cost of your filtering solution if you have some spare hardware that can be used. We where sent a trial version of the product that we installed and on the whole it was a very good filtering product, it used the Tru-Veiw technology from Bloxx and had good reporting. The same problem also plagued this product as it also did not pick up anonymising proxies and another issue was not in functionality but was in the fact that it had not been re-branded and Bloxx error pages and the like where still visible. Again the user interface is good and is on a par with the Bloxx appliance.
Sophos sent us a loan product WS500 we plugged this in and went throught its setup routine 10-15 minutes later it was up and running. This has a good dashboard that shows at a glance the number of concurrent connection, throughput and added page latency. The box has some of the best reporting we have seen in a web filtering product and the user interface is straightforward and easy to use.
SmoothWall we downloaded this product and installed it on a spare desktop we had in our office. This is a very good product a bit rough round the edges and has some features that the others did not. The one that shone out was the ability to give some control away to groups of users (Teachers) to allow sites for a period of time via a web page, we could see where this would save us as ICT Services time, and help teachers in the classroom. As I said the user interface is not as polished as the others we tested this also meant that it was not the easiest to navigate around and the reporting although not as good as the Sophos box it was not the worst in the test.
Crunch time and it was between Sophos and SmoothWall this was due to what we thought was the complacency/ arrogance of Bloxx as we felt that they thought that they had our business and was not prepared to move much. SmoothWall was bang on and we where tempted to just take them up on their offer but as we run Sophos AV products for Exchange and desktops and this was also up for renewal we decided to talk to them and the deal we got was to good to be true so we snapped their hands off! we ended up getting the WS1000 appliance from them and to be honest the more we use it the better it is, and have no problem in recommending this product to anyone in the market for a web filtering solution.
