In this article you'll find an overview of all security related articles for VPSs in our knowledge base. This includes information about what you can do to secure your VPS, but also what we do (e.g. DDoS protection).
One of the most important tips we can give you for securing your server (and what you host on it), is to keep it up-to-date. Frequently check for and install updates for your OS, software, hosted CMS-systems and its themes / plugins if applicable (e.g. WordPress).
