Network filtering


BT operates the Cleanfeed filter on its network which blocks illegal child sexual abuse content and content blocked by order of the courts[2][3].


A 2023 court order refers to BT networks using an IP blocking technology known as RedCard.

BT Parental Controls

BT introduced a network-level filter for adult content, BT Parental Controls, in December 2013[4]. In 2013 it was reported[5] to be using Nominum as its source for site categorisation. BT spent a "seven figure sum"[6] obtaining the system.

Court-ordered blocks

BT uses a combination of Cleanfeed and DNS request-blocking for court ordered blocks.
