If a service is publicly accessible, anyone can access it. Even if it’s secured, there can be security issues in the auth layer of the app, improperly secured endpoints, etc.
If a service is only available over VPN, nobody can access it unless they’re on the VPN. The service isn’t visible over the public internet and other people won’t even know it exists. You can require two factor auth to connect to the VPN.
I’m not sure why you seem to think that a private network isn’t more secure than a public network. There’s a reason why practically every company requires people working remotely to connect to a VPN to access company resources.
I never said anything about using the VPN as an ACL. All I said was to only expose the service over the VPN. That doesn’t necessarily mean that the app doesn’t have authentication or authorization.
I’m also only talking about residential use cases, where it’s a common practice (when not using a VPN) to just expose everything via port forwarding. Businesses aren’t setting up Jellyfin on their servers.
true, fun fact a VPN is also an application with an auth layer. dun dun dun!
Sure, but someone would have to first get on the VPN, and then find vulnerable apps once on the internal network, as opposed to just scanning the internet for public-facing vulnerable systems. Wireguard (and thus Tailscale) doesn’t respond to port scans at all - it only responds to packets that are signed with a known key.
Admittedly, networking and network security isn’t my specialty so I’m absolutely sure you’ve got more knowledge in this area.

The VPN isn’t “on top of” anything, it’s instead of everything.
