'We implemented the Evolved Intelligence Signalling Firewall in April 2017 as one element of our security strategy and our commitment to protecting customers’ communication from signalling attacks and fraud scenarios. It is deployed centrally with options of local enhancements and will serve all of our European networks. The firewall is already live in most of these networks, and each is able to implement its own rules and adaption of customized solutions. Since its deployment, the firewall has successfully blocked millions of category 1, 2 and 3 threats to our networks and customers. In particular, none of our customers were impacted by this year’s major banking fraud, which intercepted two-factor authentication text messages. Evolved Intelligence quickly addresses new threats and effectively provides new functionalities. Our state-of-the-art solution provides our valued customers with the best security and fraud protection'. Deutsche Telekom AG
