How Russia Helped Build Iran’s Digital Prison
Iran’s internet shutdowns from December 2025 through January 2026 were the longest in the country's history. UN Special Rapporteur Mai Sato estimates casualties from the associated crackdowns range from 5,000 to 20,000. Iranian authorities have shifted to a "white-listed" model of internet access, blocking global connectivity by default through infrastructure-level control. The Role of Russian Technology Analyses suggest significant Russian influence in the deployment of Iran’s censorship architecture, specifically relying on Deep Packet Inspection (DPI) technology. Protei, a firm with roots in St. Petersburg, has supported Iran’s interception, traffic management, and monitoring systems. Documentation for Protei's DPI platform confirms its capability to identify, block, or throttle specific protocols, including messaging, file sharing, and VoIP services. Global Reach and Clients Protei serves numerous authoritarian regimes; its client list includes MTN Irancell in Iran, Tcell in Tajikistan, Uztelecom and Ucell in Uzbekistan, Zong 4G in Pakistan, and Safaricom in Kenya. Citizen Lab research from 2023 linked Protei to the development of mobile surveillance systems for the Iranian mobile provider Ariantel, covering user authentication and network signaling. Corporate Structure and Outlook In 2024, the Russian state-owned telecom operator Rostelecom entered into a joint venture with Protei, with industry experts suggesting a potential full acquisition by Rostelecom in the future. Despite international scrutiny, Protei maintains operations across branches in Russia, Jordan, and Estonia, claiming to support over 400 customers and 300 million subscribers worldwide.
