Iran Internet infrastructure

The organisation is responsible for the operation and maintenance of Iran's national internet infrastructure. It oversees both fixed-line and mobile telecommunications networks that provide connectivity across the country. A core function of the organisation is to ensure continuous and reliable internet service for users throughout Iran. To protect this infrastructure, the organisation employs a cyber‑defense capability known as the Digital Fortress (DZHAFA) system. The DZHAFA system is designed to detect and mitigate large‑scale distributed denial‑of‑service attacks targeting the networks. In addition to DDoS mitigation, the organisation has used DZHAFA to counter previous state‑sponsored cyber operations and espionage attempts against government systems.

The organisation's headquarters is located in Iran, reflecting its national scope. Its reach is nationwide, as demonstrated by the February 8 2020 incident that disrupted approximately seventy‑five percent of the country's internet for seven hours. During that event, authorities activated the DZHAFA mechanism to repel a highly distributed denial‑of‑service attack affecting both fixed‑line and mobile services. The successful neutralization of the attack showed the organisation's ability to mobilize its cyber‑defense resources under pressure. Prior to the 2020 incident, the DZHAFA system had been deployed in response to earlier cyber threats, indicating a established defensive posture. While the organisation's exact ownership or parent‑subsidiary structure is not detailed in the available sources, it functions as a key component of Iran's critical communications infrastructure.
