From Solid Oak Software:
Cybersitter gives adults the ability to limit children's access to objectionable material on the Internet. Parents can choose to block, block and alert, or simply alert them when access to these areas is attempted. Working secretly in the background, Cybersitter analyzes all Internet activity. Whenever it detects activity that the parent has elected to restrict, Cybersitter takes over and blocks the activity before it takes place. The program's intelligent "content recognition" system even recognizes and filters brand new sites that contain objectionable material. Cybersitter also offers selectable blocking of WWW, Newsgroups, Chat, Mail, and ICQ. If desired, Cybersitter will maintain a complete history of all Internet activity, including attempts to access blocked material. Password-protected, Cybersitter is easy to deactivate or reconfigure by the parent, and virtually impossible for the child to detect or defeat.
