Although there are free trials with some of this software, some of the full versions are not free - unless marked accordingly.
Providing safer surfing for little ones - while still leaving adults with the ability to override it and see what they wish to.
Parental Internet Locks
These sites provide products which can make surfing the internet a safer place for children - and for people who do not wish to be bombarded with material which they may find unsuitable. In addition to filtering sites of a lewd nature, the filters can also screen for violence, drug and bomb and similar links. A filter should never be relied on as a "cast iron guarantee" of safety - but should be seen as a useful tool to assist parents, carers and teachers in their efforts to enable safer surfing. Weblocker seems to offer a good selection of options - enabling children of different ages to have access to different material.
We will be adding to this list as and when we find other products.
http://www.weblocker.com/ This one is completely free to download and use now - and allows adults to override it.
NB: To find this, click the "parents teachers" link at the bottom of the screen and then about halfway through the text, you will find a link to zeeksafe.
