The upper midsize customers in the DACH region has a very high security need and requires, in order to continue to be successful, a high agility in the implementation of new ideas and solutions. We help to fulfill these requirements and needs with our Sustainable AWS Landing Zone approach. In a few days we implement an AWS Landing Zone based on the AWS Control Tower with the customer's internal experts. We directly implement best practices and jointly define specifications and concepts. We also integrate the expertise of the customer's CISO and security experts into the conceptual work, so that a comprehensive, sustainable AWS landing zone is created as the basis for the customer's relevant workloads. We guide the customer in IAM, encryption, log management, provisioning of AWS accounts, best practices in different dimensions and strong security specific solutions. This prepares our customers for productive use of the AWS Landing Zone and allows them to get started right away.
