We're failing in our duty to protect children online, according to a new report.
CyberSafeIreland says a third of children have not discussed their activities on the internet with their parents.
More than two-thirds of teachers (69%) say they have not been given enough resources to teach online safety.
It also found that 16% of the children surveyed spend 'in excess' of 4 hours online a day.
22% of the children said they were in online contact with strangers.
CyberSafeIreland's Programme Director Cliona Curley says parents need to be proactive.
She says kids love to talk about their favourite YouTubers and games, "so it really helps if you can engage them on a positive level".
