Security on the Internet is no longer the work of one talented individual, or even a team of talented individuals. Security comes from collaboration, from working together with others (industry, academia, and government) to share information and best practices. With over 20 years of experience in building some of the largest broadband networks on Earth, Chris has built a career at creating these collaborations and bringing people from different backgrounds together to solve difficult and complex problems. Chris is the customer security lead at Charter Communications, chairman emeritus of MAAWG, & treasurer of the technology coalition against online child sexual exploitation. In the past, Chris taught computer science at Williams College, and has held senior engineering positions with broadband service providers in the US, Germany, and Singapore.
