Secure solution: Cyber Defense for CORPUS SIREO

With Cyber Defense for SMEs, the real estate group provides audit-proof evidence of its internal company security policies

Cyber security for SMEs


CORPUS SIREO and T-Systems have been working together for many years in all areas of IT. The general increase in threats from cyberspace attacks and the desire for comprehensive transparency in IT security led to the implementation of Cyber Defense for SMEs. With the platform-based Cyber Defense solution, CORPUS SIREO gains the desired audit compliance and proof that its own security policies are adhered to. Thanks to the "out of the box" principle, the company also benefits from low costs when purchasing and operating the solution.

With Cyber Defense, we have found an effective solution to protect our customers' data at the highest level of security.

The Cyber Defense solution reports conspicuous access attempts and records a wide variety of events from networks, systems, and applications. A central cloud platform analyzes the data and transmits alleged threats to the T-Systems' Security Operation Center. Here, experts assess the situation and, in the event of a corresponding threat, immediately inform the management of CORPUS SIREO, who can immediately initiate defensive measures.
