I finally understand Cloudflare Zero Trust tunnels

what's the difference between this and a reverse SSH tunnel, for example making a local port on your laptop accessible to a public-facing internet server or even running on localhost on that same server... or using sshuttle to access your local network from a remote server .... it doesn't sound like "zero trust" if you're proxying everything through some third-party company that you know nothing about what they're doing with your actual data that you're sending across the wire...

Zero trust is a marketing term used by them - surprisingly it has nothing to do with end-to-end encryption also.
