Because all adult material on the Internet must be accessed by using a textual command, Net Nanny is able to prevent access by storing a list of sites that are off-limits. Likewise, a child's personal information is kept in the dictionary - and if any details are typed on the keyboard the system will automatically shut down. Net Nanny cannot be turned off except by the Administration Program.
Net Nanny monitors all activities taking place on the PC - not just Internet-related activities. For example, if someone sends a pornographic picture as an email attachment which is later decoded for display - Net Nanny will not be fooled! It watches the activities on the PC in real-time.
A Macintosh version is anticipated. See the vendor's site for details.
Net Nanny is available in Europe from Leaf Distribution, Basingstoke, UK.
