ICT: protecting people and nations

T-Systems’ highly reliable ICT solutions support the work of national and international security organizations.
T-Systems’ command and control systems, for example, filter vast amounts of data and deliver relevant information to security and defense forces. This makes it possible to analyze data in near real-time, and quickly gain an accurate overview of the situation – for more effective decision-making and rapid deployment of resources. In addition, T-Systems develops and operates solutions tailored to specific tasks for the armed forces, the police, and fire departments.

Encrypted digital mobile voice and data communications

TETRA (terrestrial trunked radio), a digital radio standard, enables government agencies and organizations with security mandates to communicate reliably and securely – and completely independently of public cellular networks. T-Systems is an experienced partner in the defense space – providing networks and solutions that support organizational tasks, reconnaissance, command, logistics and communications. It goes without saying that the Deutsche Telekom subsidiary fulfills all tactical and operational requirements in terms of security, real-time operations, and other mission-critical criteria.
T-Systems’ SIMKo solution enables secure mobile communications. It is recommended by the German Federal Office for Information Security (BSI), and provides protection from external threats thanks to end-to-end encryption. Data is accessed via tunneled connections, and if a SIMKo smartphone is lost, it cannot be used by unauthorized party.

SiMKO (secure mobile communication) is the only solution for secure mobile communications recommended by the German Federal Office for Information Security (BSI). It safeguards smartphones from unauthorized access, and provides end-to-end encryption. This means that emails, calendar data and contacts are well-protected.


The digital radio standard TETRA (terrestrial trunked radio) enables users to communicate reliably and securely – and completely independently of public cellular networks. T-Systems’ TETRA project team includes experts for the design, deployment and operations of these solutions.
