Monitoring children's use of social network sites.

Below is a link to a computer program that parents can use to monitor their children's use of social network sites.  
If a child accesses inappropriate content or if strangers try to make contact with children via the internet and vice versa this can be highlighted by the program.
It can be used for multiple devices in the home and there is a phone app available that can alert you to any unsafe internet activity in the house.
