Instead of simply banning VPN services on the Internet, Iranian authorities acted more competently: they introduced VPN
licensing and now
collect millions of dollars from their citizens , while retaining the possibility of censorship and control over passing Internet traffic.
Since 2011, an advanced deep inspection (DPI) and traffic filtering system called FilterNet, an analogue of the “Great Chinese firewall,” has been operating on the Iranian Internet. The country is officially blocked by Facebook, Twitter and other sites. But if you pay a couple of dollars to the VPN provider, you can use the Internet more or less normally. About 20 million Iranians access the same Facebook via VPN. Not a bad business for the state.
The operation of VPN services in Iran has been
formally banned for several years, but de facto many VPNs openly offer their services. According to
official statistics , almost 70% of young people use VPN to access the filtered resources.
Iranian Cyber ​​Police (FATA) has waged war against VPN over the years, but without success. As a result, the authorities changed tactics, and now there are several VPN services in the country that
have received permission from the authorities : Pardakht Net, Sharj Iran, Jahan Pay & Baz Pardakht and others. To purchase a subscription, an Iranian citizen must provide identification documents and pay for the service from an official bank account.

The authorities are hiding their connection with these VPN services, but independent researchers say that 70% of the VPN market is actually “covered” by government agencies. At the same time, the authorities periodically conduct successful attacks on Tor, as
in July 2014 . After all, free and anonymous Tor competes with commercial VPN.

Well, you need to recognize that implement censorship, then introduce a paid service to circumvent it, and follow the users of this service is a very clever approach to spying on the population. A good example for the Russian authorities, however sad it may sound for the users themselves, who are inspired by a false sense of security, are deprived of their freedom of choice and are subject to additional “tax”.
