You can even go completely free with Cloudflare tunnel with your own office/home hardware. I have a simple web running on my old Raspberry Pi 3 + nginx + golang web app. Also with ssh access to the Pi.
I ended up turning that off and switching to Tailscale. Tailscale is set to advertise my home IP range (I chose one that's not 192.168 based which avoids problems with range conflicts). So I can just connect to Tailscale and connect to 10.X.Y.Z as though I'm home. If I want memorable hostnames I can point DNS records to those private IPs.
As I understand it it is a reverse tunnel from your internal network to cloudflare? If your device is compromised it may lead to an attacker using that tunnel to access your internal network through the host device?
