Some Iranians have been taking the streets in the last few weeks protesting the government and asking for more freedoms. The protests have been met with violent resistance from the government’s forces on the ground, and with tightening censorship online.

After years of growing restrictions online, Iranians know a thing or two about getting around their government’s censorship system, colloquially known as the “Filternet,” and they often turn to circumvention services like Virtual Private Networks, or Tor. Censorship circumvention isn’t done just with ad hoc apps though.
