Globally, Internet censorship is on the rise and Iran has been portrayed as one of the most critical cases. So far, however, no studies have investigated the issue from an inside look. To fill this literature gap, the present paper aims to provide an overview of Internet censorship in Iran, by assessing the Iranian perspective on Internet freedom, different aspects of the subject, as well as the domestic and foreign types of limitations clients face today. This study has shown that Iran’s current filtering policy is a lenient one pursuing Internet development and simultaneously providing protection against potential threats. The Iranian case also includes some global issues such as censorship imposed due to the U.S. sanctions. Specifically, the findings of this study revealed that the range and extent of restrictions imposed on the Iranians’ access to mobile applications by the U.S. are significantly more than those placed by the Iranian filtering regime.
