I just have all my services exposed through reverse proxy with whatever authentication they have on their webpage. I see most people using VPN which I know is the more secure option but I like the zero setup of just typing in the name of the service I want to go to and just having it work. Is there a better way to secure this?

This is Heimdall. You can add your apps and links to them and then link their API to show statuses.

I have some custom CSS on top of it which I found with a couple of quick searches.
