Tor is free software for enabling anonymous communication. The name is derived from an acronym for the original software project name The Onion Router. Tor directs Internet traffic through a free, worldwide, volunteer network consisting of more than seven thousand relays to conceal a user's location and usage from anyone conducting network surveillance or traffic analysis.
Before hitting the open Internet, the Tor Browser will connect to several different relays, wiping its tracks each step of the way, making it difficult to figure out where, and who, you really are. While Tor is gaining a reputation as a tool for buying illicit goods online, the software has numerous legitimate uses. Activists masking their location from oppressive regimes and journalists communicating with anonymous sources are two simple examples.
