Static passwords serve as a welcome mat to attackers. By contrast, two-factor authentication shields sensitive data and infrastructures from spying. The one-time passwords are generated through hardware or software tokens, for example, by apps, key rings, chip card, or sent via text message as an mTAN.

Accredited trust services provided at the highest security level

A trust center acts as an independent certification body and trust authority for electronic data exchanges. T-Systems is accredited as a trust service provider by the German Federal Network Agency. To ensure the highest level of protection, all services offered by the trust center are based on the very latest security technologies – including those for encrypting data and networks or for providing two-factor authentication.

Highly secure trust center environment

A high security environment based in Germany consisting of geo-redundant data centers backs up all services. If a crash occurs in one area,a second data center (in which all data, the entire IT infrastructure and all network connections are mirrored) will automatically spring into action. By taking this approach, T-Systems not only ensures dependable and highly available operations, but also complies with the most stringent German and European requirements for data protection and security.

Highest level of confidentiality

The provision of certification is performed in the company's own trust center and is performed exclusively by trained personnel who have undergone security checks. The result is the provision of certificates at the highest security level. T-Systems can guarantee secure electronic data exchanges even for extremely sensitive information.
