A tool that protects your computer against network traffic analysis and surveillance

What's new in Tor

  • Major features (Proposal 310, performance + security):
  • Implements Proposal 310, "Bandaid on guard selection". Proposal 310 solves load-balancing issues with older versions of the guard selection algorithm, and improves its security. Under this new algorithm, a newly selected guard never becomes Primary unless all previously sampled guards are unreachable. Implements recommendation from 32088. (Proposal 310 is linked to the CLAPS project researching optimal client location-aware path selections. This project is a collaboration between the UCLouvain Crypto Group, the U.S. Naval Research Laboratory, and Princeton University.)
  • Major features (fallback directory list):
  • Replace the 148 fallback directories originally included in Tor (of which around 105 are still functional) with a list of 144 fallbacks generated in July 2020. Closes ticket 40061.
Read the full changelog

Tor is an open source computer software designed as a network of virtual tunnels that can be used by a wide range of people and organizations who want to improve their security and safety while surfing the Internet.

Defend yourself against traffic analyzers and network surveillance

When one says Tor, it may refer to the actual application or the entire network of computers that form this project. With Tor, users will be able to defend themselves against traffic analyzers and network surveillance.

The project protects your privacy and secures your top secret documents from pesky government institutions, such as NSA (National Security Agency). It prevents hackers from learning your browsing habits or discover your current location.

Supports mainstream web browsers and operating systems

It works well with any web browser, instant messaging client, and many other applications that access the network. It’s supported on Linux, Android, Microsoft Windows and Mac OS X operating systems.

How does it work?

In order to understand better how Tor works, you should know that when you are connected to the Tor network and you want to access a certain website with your favorite web browser, the connection will be redirected from one computer to another before it reaches its destination. Once the application is installed, configured and started, it will automatically route all the network traffic from your computer transparently over the Tor network.

Tor work as a distributed, anonymous network comprised of all the computers where it is installed and active. For example, if you install the application in your computer, you will automatically become part of the Tor virtual network, every time you use it. This way, no one will know your IP address, location, etc., and random IP address will be displayed to those who try to track you. It’s best to use Tor when you really want to hide your online activity from someone, but especially when you are in public networks.
