Cloudflare Access can secure connections over Secure Shell (SSH)

Doing so requires configuring your Access-protected server to use Argo Tunnel for SSH connections. Argo Tunnel exposes your origin server directly to Cloudflare, avoiding external internet connections. Using Argo Tunnel ensures that Cloudflare evaluates all requests to your application.

Establishing an SSH connection to an Access-protected server requires installing Cloudflare's cloudflared command-line tool on the client machine so that it can connect over Argo Tunnel.
