@andreasdueren I'd be cautious about implementing it then. Cloudron hardens your server enough - doing more by installing more software, which is NOT recommended, will only lead to problems, especially if you don't already have a deep enough understanding of what is happening. It seems to be that @BrutalBirdie's gang knows their stuff (they're using Ansible to install Cloudron??? Yeah, that is next level coding there). Of course, they may also be paying for the Enterprise level of service (I'm not asking btw, no need to respond to that @BrutalBirdie ) so if they have hassles then I suppose it's fine for them to get help beyond typical Cloudron support, especially if they are doing more to their servers than what Cloudron themselves advise.
