Creating Safe Internet Zones is a second option for controlling Internet access. By default it blocks the user from accessing any web sites. You then add permitted web sites to a list to which you do want the user to access. This is done by making a list of websites, which you decide are suitable for each user to view - the user will only be able to visit those sites on the ‘safe’ list.
In the ReassureMe.com Netintelligence Control Centre, this is called 'Safe Internet'
Everything except those websites appearing on the safe list will be restricted.
