Web Application hosting

Hi! I'm in need of a web application host for an educational & ERP web application. The website will require advanced security measures, as it needs to provide a safe online environment for use. I have decided to go with Contabo hosting. I am confident that Contabo will provide the necessary resources to ensure that my web application is hosted securely, we have already used contabo for previous hosting and now it is down so we need to reconfigure it. Thanks in advance for your assistance!
