Cloudflare Introduces Argo Tunnel: A Private Link to the Public Internet

Yesterday, Cloudflare introduced Argo Tunnel, a private connection between a web server and Cloudflare.

Tunnel makes it so that only traffic that routes through Cloudflare can reach your server.

You can think of Argo Tunnel as a virtual P.O. box. It lets someone send you packets without knowing your real address. In other words, it’s a private link. Only Cloudflare can see the server and communicate with it, and for the rest of the internet, it’s unroutable, as if the server is not even there.

One reason why traffic through Argo Tunnel gets a performance boost is that Tunnel is built on top of Argo, Cloudflare’s optimized smart routing.
