What is Tor?
Tor is free software and an open
network that helps you defend against traffic analysis,
a form of network surveillance that
threatens personal freedom and privacy, confidential business
activities and relationships, and state security.

Why Anonymity Matters
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.
