With locations in more than 20 countries, 37,500 employees and an external turnover of 6.9 billion euros (2018), T-Systems is one of the world’s leading cross-vendor digital service providers headquartered in Europe.

T-Systems supports its customers on the way to digitization. As a company, we offer integrated solutions for business customers. At the Deutsche Telekom subsidiary, everything comes from a single source: from secure operation of existing systems and classic IT and telecommunications services to transformation into the cloud, including international networks. From the demand-oriented provision of infrastructure, platforms and software to new business models and innovation projects on the Internet of Things. This is based on global reach for landlines and mobile communications, highly secure data centers, a comprehensive cloud ecosystem with standardized platforms and global partnerships, and the highest level of security.
