We manage enormous amounts of data for our customers. Sustainable data management means using resources efficiently and minimising the ecological footprint. An important keyword when it comes to sustainable data is data resilience. This refers to ensuring business continuity in the event of natural disasters, hackers and all incidents that could result in data loss. Specifically, the cloud is an ideal platform for protecting data from these threats and saving resources. We therefore attach great importance to the security of our data centres and the availability of customer data. These efforts are implemented through multiple secured access points to the data centres, video surveillance of the rooms, high fire protection requirements, NEA and UPS systems, regular maintenance of the IT and infrastructure as well as state-of-the-art firewalls.
