Broadband provider TalkTalk has already blocked more than one million websites at the request of its customers.
Dido Harding, Chief Executive of the firm, explained that TalkTalk already offers network level parental controls, protecting all web-enabled devices using the home broadband connection.
Last week, the Bailey Review proposed a range of measures designed to protect children using the internet, including blocking access to adult websites.
Ms Harding said TalkTalk welcomed the recommendations, adding that parents should be offered an 'active choice' about whether to use parental controls.
TalkTalk has already been offering such services for some time.
"We launched HomeSafe for free for all our customers because we believe in safe broadband, affordable for all," she noted.
"We think that all parents should have the ability to block undesirable content and, crucially, they should not have to pay a premium to do so. Since we launched HomeSafe we have blocked one million websites at our customers' request."
Ms Harding said it was "encouraging" to see the government's continuing commitment to helping parents understand the opportunities and risks of the internet.
HomeSafe allows customers to block certain categories of content from reaching any device – PCs, laptops, games consoles, tablets and smartphones.
According to TalkTalk, the three most commonly blocked categories of content are Suicide & Self-Harm, Pornography and Violence & Weapons.
