Available Locations: Remote - US About the Team

Cloudflare helps build the future of the Internet. We started Cloudflare to solve one half of every IT organization's challenge: how do you ensure the resources and infrastructure that you expose to the Internet are safe from attack, fast, and reliable. We saw that the world was moving away from hardware and software to solve these problems and instead wanted a scalable service that would work around the world. To deliver that, we built one of the world's largest networks. Today our network spans more than 250 cities worldwide and is within milliseconds of nearly everyone connected to the Internet. We have built the capacity to stand up to nation-state scale cyberattacks and a threat intelligence system powered by the immense amount of Internet traffic that we see.

We are now expanding Cloudflare’s product offerings to solve the other half of every IT organization's challenge: ensuring the people and teams within an organization can access the tools they need to do their jobs and are safe from malware and other online threats.

To do that, we released Cloudflare Zero Trust Platform, a Zero Trust platform built on Cloudflare’s network to secure users, devices, and data in organizations of any size. Cloudflare for Teams consists of multiple products that deliver a comprehensive solution. Those products include

Cloudflare Access, built to replace VPNs and protect internally-managed applications. Cloudflare Tunnel, the best way to connect your infrastructure to Cloudflare in a secure way. Cloudflare Gateway, a tool that keeps team members protected from malware and other threats on the Internet. The Cloudflare Zero Trust Agent, the secure on-ramp for your traffic to the Internet.

What Makes Cloudflare Special?

We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: We equip politically and artistically important organizations and journalists with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost.

Athenian Project: We created Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here’s the deal - we don’t store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
