In this talk [WebXray](www.webxray.eu), a consultancy specializing in the auditing of online web tracking, will illustrate the scale of the problem in enterprise and explain its origins.

As privacy engineers, WebXray demonstrate open-source [tools](www.webxray.org) which audit illicit practices.

There is an alternative the dominant business model of targeted advertising. We will advocate how we can create a pathway towards responsible, privacy-friendly online platforms.
