Cyber Index

We play a vital role in protecting people from cyber attacks.

We want everyone to feel safe when using our technology, so we work behind the scenes to help our customers protect their devices - from both large scale attacks and more targeted attempts to steal data.

The BT Cyber Index pulls together some of the key cyber data that we are monitoring across our networks. It highlights key trends and events, explains what these mean and shows how we are protecting you from cyber threats.
