Internet safety is "the road safety of our children’s generation", according to broadband provider TalkTalk.
Dido Harding, Chief Executive of the firm, said a combination of IT security products, better education and information for families is needed to combat online threats.
"We believe that giving customers an active choice about using controls like HomeSafe is the most effective way to engage them in internet safety," she stated.
"TalkTalk remains the only [broadband provider] that asks new customers to make an active choice about using parental controls, and we are working on plans to roll out this active choice to our existing customers."
Ms Harding said that since the firm launched active choice for new customers in March, one in three has chosen to activate the controls.
She said that 80 per cent of TalkTalk customers think being offered the choice of using filters upfront is a good thing.
And over 60 per cent said they would not have turned on parental controls had they not been asked to make a choice.
"There is no silver bullet when it comes to keeping children safe online and no security solution can ever be foolproof, whether that’s online or in the real world," Ms Harding stated.
"But it is critical that we offer parents the choice to use simple and effective tools like HomeSafe to help make children safer online."
