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.
