IT security

We make IT secure

Virtually every company in Germany has been the target of at least one cyber-attack. The situation for personal internet usage is also alarming: Every second user has been the victim of cyber-crime. This is not about to change,
so the issue of IT security is of paramount importance. Telekom Security is the market leader for IT security solutions in Germany and brings together the Group's full range of cyber-security expertise. It offers customers – private individuals, SMEs, and major firms alike – products and solutions designed to protect every aspect of their IT networks, from smartphones to corporate infrastructures.

No security – no digitalization

We want to make security easy for everyone. Easy to order, easy to install, and easy to use. These are our guidelines when developing comprehensive security strategies for companies, organizations, and government institutions.

Telekom shapes the future of digital so it can bring people closer together. However, digitalization is not possible without security. Cyber-security is the key factor for making the internet of things a success, because protecting data is essential if companies want the market to accept their new business models. Team up with us: Together, we can create a secure infrastructure for the future and, at the same time, establish the conditions that digitalization needs.
