This research bulletin analyzes the aftermath of the Telegram ban in Iran and presents detailed data on the performance of Psiphon, one of the most widely used circumvention tools among Iranians. However, users expressed serious concerns about the security of state-sanctioned applications, and considered them to be facilitating state surveillance. Much of the state’s effort centered on migrating Telegram users to domestically developed alternatives. Iranian users rushed to apply circumvention tools to stay connected to Telegram despite the concerted efforts of different political bodies to diminish attention to the app.
