Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis. Originally known as "The Onion Router".
Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.
The Tor network gained further mainstream prominence following the NSA surveillance scandal in June 2013 and is featured on the "PRISM Break" website.
According to privacy advocates, "Use a combination of Tor Browser and another free browser to surf the web. Try to use Tor for as many things as possible. Browsing the web may be slower, but it will offer you far better anonymity. Make sure to learn the basics of Tor before using it."
Tor has been widely criticized for abuse. Some networks and websites intentionally use Tor exit lists in an attempt to block the network.
