In this report, we introduce the design of GFWatch, a large-scale longitudinal measurement platform that informs the public about how GFW censorship changes over time and its negative impact on the free flow of information.

This call comes on the heels of recent Citizen Lab research which shows that Netsweeper, a Canadian company who has received funding from the Canadian government, is being used by governments to block access to content in ten authoritarian countries around the world, including LGBTQ2+ sites.

This report describes our investigation into the global proliferation of Internet filtering systems manufactured by the Canadian company, Netsweeper Inc.

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.

In this section, we spotlight several countries where we have evidence of public ISPs blocking websites using Netsweeper’s products. Each country has significant human rights, public policy, insecurity, or corruption challenges, and/or a history of using Internet censorship to prevent access to content that is protected under international human rights frameworks.

This section examines the legal, regulatory, corporate social responsibility, and other public policy issues raised by our report’s findings. We focus on the responsibilities of Netsweeper, Inc. and the obligations of the Canadian government under international human rights law.
