Published by the Review of Policy Research, this paper by the Citizen Lab’s Ron Deibert, Joshua Oliver, and Adam Senft takes a deep dive into data provided by the circumvention tool Psiphon to reveal Iran’s increasingly sophisticated Internet blocking strategy around elections.
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.
