How is iShield different from URL Filtering Software?
URL filters only restrict access to known pornographic web sites and so are dependent on the list of known web-sites being up to date. This dependency is important since there are in the region of 100,000 new pornographic web-pages being placed on the Internet each day. iShield does not use any lists of known pornographic websites, instead it analyses each web-page as it is loaded finds pornographic images and then blocks them.
