Internet is a global network that brings countless information and content and enables to communicate quickly. Although the usefulness of the Internet is indisputable, the dangers that threaten children on the Internet are being discussed more often. Some of the dangers that a child may encounter using the Internet are child pornography, pedophilia, identity theft, inappropriate content, abuse on the Internet, and the possibility of creating an Internet addiction. Parental control in the virtual world is crucial to minimize the possibility of facing dangers on the Internet. There are numerous applications that can make it easier for parents to control their children in the virtual world. The most prominent parental protection applications are FamiSafe, Google Family Link, Qustodio, Norton Family Parental Control and Kids Place Parental Controls. They can be downloaded from the Google Play Store platform. The results of the research conducted on 106 participants (parents) confirm the hypothesis that children of early and preschool age spend more than an hour a day on the Internet (43.9%). The hypothesis that parents are not familiar with the forms of the Internet protection was not confirmed (78% of research participants are familiar with the methods of protection on the Internet). The hypothesis that parents of children of early and preschool age are not aware of the dangers on the Internet was also not confirmed (95.1% of parents state that they are aware of the dangers). Children, as the most vulnerable group of our society, need help from adults in order to handle the world of technology as well as possible.
