Tor can help protect you against network surveillance that threatens personal freedom and privacy, confidential business activities and relationships.

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.

Tor can't solve all anonymity problems. It focuses only on protecting the transport of data. Please check the available documentation before using Tor.
