About the team
The Zero Trust Connectivity team builds the hub that connects Cloudflare One and Zero Trust products such as Cloudflare WAN, Cloudflare One Client, Cloudflare Tunnels, Gateway and Workers VPC. Powering this hub is a set of Rust-based services operating on every one of the data-centers that Cloudflare runs. These services route all of Cloudflare One traffic end to end. By leveraging Cloudflare's incredible infrastructure and programming languages such as Rust, this critical service is safe, performant and secure.
As Cloudflare Zero Trust set of features evolves, this team is responsible for evolving these hub services to deliver those new capabilities while guaranteeing scalability and reliability as top priority.
