A centralized and standardized IT environment poses the risk of excessive dependence on a single system or data center since a system failure could have serious consequences for the entire company. We aim to minimize this risk by means of a number of safety mechanisms, including access control systems, emergency planning and uninterruptible power supplies for critical systems and redundant data storage. We use firewall systems, virus scanners, etc., to protect our IT systems against data security risks resulting from unauthorized access.
