Introducing Lightway

Lightway is ExpressVPN’s state of the art mobile first VPN protocol. Designed for simplicity in a modern connected world, it now helps to provide Internet privacy for millions of people around the world. In this talk I cover what protocols the VPN industry has used, the rise of Wireguard with the privacy issues it raises, and a discussion on the design and focus points for Lightway itself.

Creating Trusted Server

Operating a consumer VPN platform for millions of users where not only performance but security and privacy are vital components can be extremely challenging. With thousands of servers, keeping them all updated, with known and verified software is essential but deployment tools such as Ansible don’t scale well for this task, and how do you handle the huge variety in data centers?

Trusted Server is a ram-only operating system that boots from a cryptographically signed ISO to ensure that each server is running exactly what it’s supposed to at all times. With an innovative approach to constantly refresh servers, Trusted Server led the charge for this next-gen approach to VPN platform management.
