Over the past few months, we’ve also been working to enhance stability and persistence. You can also add a Zero Trust policy with Cloudflare Access to your DNS record so that only friends and collaborators can view your resource. Then, you would create your Tunnel and generate a hostname in the Cloudflare dashboard using your Tunnel UUID so that users can reach your resource and run your Tunnel. You would first install cloudflared to connect your origin to Cloudflare. With that, suppose you are working on a local development environment for a new web application and want to securely share updates with a friend or collaborator. More importantly, you can actually enhance the security controls of your origin by enforcing Zero Trust rules through Cloudflare which validate each request to your resource. This removes legacy model requirements of poking ingress rules into your machine often leaving your infrastructure vulnerable to attack. Tunnel secures your origin by making outbound-only connections to Cloudflare. This is commonly referred to as a reverse proxy model.īut what happens if an attacker discovers that origin IP address? Couldn’t they just bypass Cloudflare altogether? That’s where Tunnel comes into play. Cloudflare is then able to use this as an opportunity to block unwanted or malicious traffic instead of would-be attackers hitting your origin IP addresses directly. The second step is important because once you change your nameservers, requests made to your resources first hit Cloudflare’s network. Since 2010, Cloudflare has onboarded new users by having them complete two steps: 1) add their Internet property and 2) change their nameservers. This was of particular interest to us as we also wanted to solve what was a key pain point for many of our own customers, too. Instead of implementing other legacy models, we wanted to create a frictionless way to establish a private connection directly to Cloudflare. It was unnecessarily difficult to connect a server to the Internet. Originally, we built Tunnel to solve a straightforward problem. This means that only traffic that routes through Cloudflare can reach your origin. Instead, this private connection is established by running a lightweight daemon, cloudflared, on your origin, which creates a secure, outbound-only connection. With Tunnel, users can create a private link from their origin server directly to Cloudflare without a publicly routable IP address. We built Tunnel to help alleviate that burden. Traditionally, from the moment an Internet property is deployed, developers spend an exhaustive amount of time and energy locking it down through access control lists, rotating ip addresses, or clunky solutions like GRE tunnels. In 2018, Cloudflare introduced Argo Tunnel, a private, secure connection between your origin and Cloudflare. If you’re interested in how and why we’re doing this, keep scrolling. You can still add the paid Argo Smart Routing feature to accelerate traffic.Īs part of that change (and to reduce confusion), we’re also renaming the product to Cloudflare Tunnel. Starting today, we’re excited to announce that any organization can use the secure, outbound-only connection feature of the product at no cost. In the past, Argo Tunnel has been priced based on bandwidth consumption as part of Argo Smart Routing, Cloudflare’s traffic acceleration feature. With this model, your team does not need to go through the hassle of poking holes in your firewall or validating that traffic originated from Cloudflare IPs. Argo Tunnel, our secure method of connecting resources directly to Cloudflare, is the next piece of the puzzle.Īrgo Tunnel creates a secure, outbound-only connection between your services and Cloudflare by deploying a lightweight connector in your environment. A few months ago, we announced that we wanted to make Zero Trust security accessible to everyone, regardless of size, scale, or resources.
