Just how secure are the various reverse proxy options? (feddit.uk)

Specifically from the standpoint of protecting against common and not-so-common exploits.

I understand the concept of a reverse proxy and how works on the surface level, but do any of the common recommendations (npm, caddy, traefik) actually do anything worthwhile to protect against exploit probes and/or active attacks?

Npm has a "block common exploits" option but I can't find anything about what that actually does, caddy has a module to add crowdsec support which looks like it could be promising but I haven't wrapped my head around it yet, and traefik looks like a massive pain to get going in the first place!

Meanwhile Bunkerweb actually looks like it's been built with robust protections out of the box, but seems like it's just as complicated as traefik to setup, and DNS based Let's Encrypt requires a pro subscription so that's a no-go for me anyway.

Would love to hear people's thoughts on the matter and what you're doing to adequately secure your setup.

Edit: Thanks for all of your informative replies, everyone. I read them all and replied to as many as I could! In the end I've managed to get npm working with crowdsec, and once I get cloudflare to include the source IP with the requests I think I'll be happy enough with that solution.

I have yet to see anything I can run myself that works as well as cloudflare. Still, not exactly self hosted.

Yeah I'm running a Cloudflare tunnel for external access (which is why I need DNS based LE certs), but that's another thing that I don't really know what it's doing beyond basic reverse proxying.

I have a country-based whitelist for where my Immich instance can be accessed from but I find the Zero Trust admin backend to be massive overkill for my needs, and it doesn't help that they've recently moved everything around so none of the guides out there point to the right places anymore!

Btw, you can do http based LE certificates through cloudflare. They just proxy the ACME URLs.

Hmm I must be doing something wrong then because it doesn't work for me.
