How do I protect my children from exposure to pornographic or violent content online?

The best protection combines technical tools with an open relationship, because no filter is perfect without your child's trust. In practice, install content filters on devices, put the computer in an open area of the home, and limit device use in closed rooms. Build an atmosphere in which your child dares to tell you if he accidentally sees something, without fear of being scolded. Explain according to his age that some things are not appropriate and why, rather than simply forbidding. Check the games and apps your child uses. Most importantly, be their go-to person; children who are close to their parents look for answers in dangerous places less. See educating the family.
