A study published on Monday by the broadcast watchdog revealed that 23% of parents in NI do not think that the benefits of the internet outweigh any risks to their child.
It is almost twice the figure recorded by households across the UK, Ofcom said.
Meanwhile NI parents are equally likely as those in other parts to feel they know enough about web safety to protect their child while they are online.
Ofcom's annual 'Media Literacy in the Nations' reports looks at the attitudes of children and parents with regards to different forms of media - including internet, phone and television usage.
It found that more than four in ten children in the region who use the internet at home do so alone and 23% have access in their bedroom.
Just under 20% go online through a fixed or portable games console, and internet access that way has increased by 8% since 2009.
Parents' worries also extend to both television content and what children can access through their mobile phones, with concern at 43% and 35% respectively.
Areas of concern include who their child is in contact with by phone, bullying via calls or text and the child giving out personal details by phone.
