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.

As well as protecting our own customers’ data, our global business customers around the world rely on our security services to protect their clients’ details. For full details, visit our website.

Behind the scenes, our Security Operations Centres monitor our customers’ devices 24 hours a day, 365 days a year, to spot breaches and potential weaknesses and to keep our network secure. We work to internationally recognised security standards like ISO 27002 (the International Code of Practice for Information Security Management).

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.
