Cloudflare Tunnel Safer Now? (alien.top)

I've seen a post on here before about Cloudflare tunnels being unsafe for exposing your locally hosted services to the web which I totally get.

However I'm a bit of a noob with complex VPN set ups and I tried to get Wireguard working in Docker but couldn't. I got a tunnel configured and exchanged all the peer keys and things but I think my initial networking docker-compose stack was incorrect possibly. Also the windows client for it is a bit ugly but that's by the by.

I've also used Tailscale in the past which is great but it feels like a temporary solution to me as you still have to remember ports and things (there may be a way around that if I remember correctly but I'd rather stay away from Tailscale. I prefer having control myself or through my domain name - probably illogical I know).

Instead I decided to try to protect the Cloudflare tunnel to my home network and I've made a policy in Cloudflare Access that won't let you in without emailing you a code (only my email address works) and having you enter it. I'd also rather adjust that to my 2FA app but I can't seem to get that to work here.

My question is: is that secure enough? And if not, what would you all suggest as an alternative (preferably an alternative that is pretty easy and means I can use my domain name)?

We use cloudflare tunnels in production for massive workloads at FiveM/Cfx.re, I can with 100% confidence say that I trust in it.

Only caveat is that if you have rapid scaling, CF might accidentally route to a non existent tunnel, and if that doesn’t resolve itself you will have to recreate it.

But this has only been an issue if you force shutdown some of the cloudflared instances. And only very intermittently, reproducing it has been difficult.

Gotcha, thanks.
