To rectify the situation, Börsen decided to move all its Hamburg-based affiliates into one single building. The goal was not only to create a more cohesive business unit, but also to achieve synergies in the technical environment. Börsen needed to create highly available Internet connections with flexible usage options and effective network security was essential.
Working with solution provider LANtana, Börsen chose a high-performance firewall system from Clavister which includes two Clavister clusters designed to ensure the secure and smooth transition of data between the Hamburg and Hannover exchanges. For increased resilience, multiple communication lines are divided into two autonomous systems which are managed by independent providers, QSC and Colt Telecom. In Hamburg, two clustered Clavister Security Gateways provide a joint firewall solution for these two systems and in Hannover, the old solution was replaced by two clustered Clavister systems.
