With a footprint in more than 20 countries, 37,500 employees, and external revenue of 6.9 billion euros (2019), T-Systems is one of the world's leading vendor independent providers of digital services headquartered in Europe. T-Systems is partnering its customers as they address the digital transformation. The company offers integrated solutions for business customers. The Deutsche Telekom subsidiary offers one-stop shopping: from the secure operation of legacy systems and classical ICT services, the transition to cloud-based services (including international networks, tailored infrastructure, platforms and software) as well as new business models and innovation projects in the Internet of Things. T-Systems can provide all this thanks to its global reach in fixed-network and mobile communications, its highly secure data centers, a comprehensive cloud ecosystem built around standardized platforms and global partnerships, and the ability to offer top levels of security. The Internet of Things (IoT) is making its presence felt in the business world – the real-time world has reached the engine room. Sensors can measure the current state of different factors with virtually no delay time and immediately pass on data such as location, temperature, vibrations or any deviations from predefined normal ranges. This is the basis for new business models and depends crucially on fast networks for the transmission of data and a high-performance cloud to transport the data to where it is stored and analyzed. In addition, the transmission channels and data pools must be secured against unauthorized access. Deutsche Telekom and T-Systems have spent billions on connectivity, cloud, IoT and security to ready themselves for the connected world.
