Tor

Tor, which stands for the Onion Routing project, is an open-source privacy network that enables anonymous web browsing. To preserve users’ online privacy, the worldwide Tor computer network employs safe, encrypted protocols. Digital data and communications of Tor users are protected using a tiered strategy that is similar to the nested layers of an onion.

The U.S. Navy was the only organization to create and employ the Tor technology originally to secure sensitive government communications. Later, the network was made publically accessible as an open-source platform, making Tor’s source code available to everybody. The Tor network’s volunteer developers constantly improve and update Tor.
