Parrot Security OS, which recently celebrated its 4th birthday [1], comes from the Frozenbox Network, an Italian network dedicated to hacking, IT security, and programming [2]. It follows in the footsteps of already mighty security-focused OSs such as CAINE [3] and WeakerThan [4] both of which were also developed in Italy.

The OS doesn't follow an official release frequency but since 2014 has released versions on roughly a monthly basis.

Version 3.1, code-named Defcon, was released in July and is based on Debian jessie. It is available both for 32-bit and 64-bit architectures, as well as ARM and IoT images, including the Raspberry Pi and Cubieboard 4 (CC80). Visitors to the Parrot Security OS website can download either the Full or the Lite version of the ISO from a variety of mirrors. Alternatively, the ISO can be downloaded via BitTorrent.
