Cloudflare Access can secure connections over Secure Shell (SSH). Doing so requires configuring your Access-protected server to use Argo Tunnel for SSH connections. Without Argo Tunnel, Access can be circumvented by using a server's public IP address. Argo Tunnel exposes your origin server directly to Cloudflare only, avoiding external internet connections.
