BT and Deutsche Telekom have opened separate security centres in Germany as they look to strengthen services for customers.
The German operator's Cyber Defense and Security Operation Centre is in Bonn (pictured), with more than 200 employees tracking its systems and those of its customers across Germany and overseas.
The staff identify attacks, work out which methods have been used, defend against them and then use the data to determine potential future routes of attack.
To date, the operator has collected more than 20 million sample attacks to improve their own systems and analyses more than a billion pieces of security sensitive data per day from 3,000 sources.
Dick Backofen, Head of Telekom Security, said the opening of the centre was part of his plans to turn Bonn into "Europe's Cyber Security Valley".
Deutsche Telekom's CEO Tim Höttges added: "By opening the Security Operation Centre, Deutsche Telekom is once more underlining the leading role that we are playing in cyber defense and IT security.
"Our customers and an increasing number of other businesses are benefiting from our know-how in internet security.
"We are working worldwide with the best partners in the field, bundling their applications and deploying them with maximum effectiveness.
"The result is that our quiver now contains all the best possible defensive weaponry against every attack."
Eschborn, near Frankfurt, is the location of BT's new Security Operation Centre, which will track BT's own assets as well as the network and IT infrastructure of customers to defend against attacks.
The operator will advise customers on how best to avoid attacks and defend against them when they happen. It said the Eschborn centre will focus on how to help German companies ensure sensitive data stays within the country.
BT has a global "follow the sun" network of 15 Security Operation Centres employing more than 2,500 security specialists.
Torsten Jüngling, General Manager for BT Security in Germany, Austria, Switzerland, the Nordics and Eastern Europe, said: “Security is at the very top of the agenda for many CIOs and CEOs as they steer their businesses through complex digital transformation journeys.
"BT has one of the most comprehensive portfolios of managed security services and an extensive global team of professional consultants around the world.
"By further strengthening our capabilities in Germany, we are determined to become the security partner of choice for companies based in the region.”
