This report describes our investigation into the global proliferation of Internet filtering systems manufactured by the Canadian company, Netsweeper Inc. After undertaking a mapping of worldwide country installations, we focus in on ten country cases in which we verify that Netsweeper systems are being used to censor the Internet for subscribers of consumer Internet Service Providers, and where human rights and corporate social responsibility questions are acute.

This section details the research questions that informed our study. We also outline in detail the methods that we adopted to identify Netsweeper installations worldwide, and those that we employed to reduce the findings to countries of interest. We also present high-level technical findings and observations.
