Past Project


The Berkman Center's Circumvention project is engaged in designing and conducting research aimed at gaining a broad understanding of the usage of circumvention tools, as well as field-building in the area of circumvention research. Activities include a workshop convening circumvention tool developers, a survey of circumvention tool usage, a survey of VPN providers, and an evaluation of circumvention tools to complement research undertaken in 2007.

This project is supported in part by the U.S. Department of State and Internews.
