Cloudflare Tunnels – are a way to securely connect your resources to Cloudflare without a publicly routable IP address. They use a lightweight daemon called cloudflared that creates outbound-only connections to Cloudflare’s global network. This way, you can hide your web server IP addresses, block direct attacks, and encrypt application traffic. You can also use Cloudflare Tunnels to access internal applications in a Zero Trust environment, without a need for a VPN.
