CORPUS SIREO: Cyber Defense detects potential threats immediately

With Cyber Defense for SMEs, the real estate group can verify compliance with its internal security guidelines in an audit-proof manner.
CORPUS SIREO and T-Systems have worked together for many years across all areas of IT. The growing numbers of threats through attacks from cyberspace and the desire for complete transparency when it comes to IT security led to the implementation of Cyber Defense for SMEs. The solution reports suspicious access and records a wide range of events across the board from networks, systems and applications. A central cloud platform analyzes the data and passes on details of supposed threats to the T-Systems Security Operation Center. Experts assess the situation and, if a threat situation exists, inform the management of CORPUS SIREO so that countermeasures can be taken immediately. This platform-based solution gives CORPUS SIREO the desired level of audit compliance and verification that its own security guidelines are complied with. Thanks to the “out of the box” principle, the company also benefits from low costs in the procurement and operation of the solution.
