They can be prevented from using certain CDs and parents will be able to track their Internet activity. Parents, according to Indigo's chief executive, Mr Shay Moran, will be able to control Internet access and the way children use computers. The product can also stop the children using parents' credit card numbers to go shopping on the net and can stop them exchanging personal information such as names and addresses. Adults may by-pass Net Nanny to see the excluded bits by using a personal code to override the software. The software may even watch for key words or phrases, so sites containing those words are off limits. When installed, it lists a range of sites that are blocked out. It enables adults to stop children accessing inappropriate material. Net Nanny is a piece of software sold here by Internet service provider Indigo. Net Nanny is there to steer children to safety.
