The web connects billions of devices, running a plethora of clients, and serves billions of users every day. To cope with such a widespread adoption, the web constantly changes. This is evident by some browsers that have a release cycle of just six weeks. These rapid changes are not always studied from a security perspective, resulting in new attack vectors that were never observed before.

The proposed workshop aims to attract researchers that work on the intersection of browser evolution and web security. Our goal is to create and sustain a new venue for discussing the rapid changes to browsers from a security perspective, the security implications of current web technologies, how we can protect users now, and make browsers in the future more secure without hindering the evolution of the web.
