Tails is ultimatum security on Snowden's orders

How to go online without leaving a trace? Is it possible to publish something while remaining anonymous? How to make a computer forget everything you did on it? All these questions are solved by the Tails operating system, which the general public learned about thanks to Edward Snowden. Tails allows you to boot on any computer from a flash drive, anonymizes your traffic using the Tor network - and then forgets everything and erases traces of your work.
