CORPUS SIREO: New corporate network

​​​​​​​A homogeneous, flexible and secure communications landscape makes the real estate group’s work easier and offers added security, flexibility and availability.
As one of Europe's largest asset managers with 11 locations, CORPUS SIREO relies on a flexible, cutting-edge communications network. As part of the migration to Windows 7, it became apparent that its WAN, which was hosted by two different providers, did not have the required performance. CORPUS SIREO therefore wanted to use a state-of-the-art, homogeneous and fully managed corporate network throughout the group in the future.
T-Systems implemented a virtual private network based on MPLS IntraSelect as the WAN platform. Juniper switches are used on the local area network (LAN). The wireless network (WLAN) and Voice-over-IP technology are operated using products from Cisco. CORPUS SIREO uses RCI (Remote Connect Internet) as a dial-in solution. Thanks to this all-round, worry-free package, all communications at CORPUS SIREO have been made significantly easier and are now far more flexible. The straightforward, secure outside dial-in option along with easy adaptability for mobile end devices optimally supports CORPUS SIREO's business, which is characterized by close customer contact.
