TOR - The Onion Router

 

The Tor Browser isolates every site you visit so that third-party ads and trackers do not follow you. After you are done browsing, the cookies would automatically clear too. The browser also mitigates others from eavesdropping your connection and finding out the sites you visited. This security-focused browser wants to make all its users appear the same. It doesn’t want you to develop an identity based on your device and browser information. Using Tor Browser ensures your traffic gets encrypted and relayed three times while passing over Tor.

The Tor Browser also lets you access the "dark web" (dot onion) web-sites. The dark web is the World Wide Web content that exists on darknets: overlay networks that use the Internet but require specific software, configurations, or authorization to access. Darknet websites are accessible only through networks such as Tor ("The Onion Routing" project) and I2P ("Invisible Internet Project").

* It is important to note that someone monitoring your Internet connection (such as your ISP or a government agency) can see that you are using Tor. However, nobody can tell what you are accessing with Tor, only that you are using it to access something on the Internet (open or dark web).

While Tor protects what you are doing on-line, the fact that you are using Tor can be used as evidence against you, as we saw in 'How Tor Helped Catch the Harvard Bomb Threat Suspect.'
