WALPOLE, MA The Tor Project releases an article about the "Ten Things to Look for in a Circumvention Tool". As more countries crack down on Internet use, people around the world are turning to anti-censorship software that lets them reach blocked websites. Many types of software, also known as circumvention tools, have been created to answer the threat to freedom online. These tools provide different features and levels of security, and it's important for users to understand the tradeoffs.

This article lays out ten features you should consider when evaluating a circumvention tool. The goal isn't to advocate for any specific tool, but to point out what kind of tools are useful for different situations.

Tor's tools and technologies are already used by millions of people to protect their activities online. These users include journalists and human rights workers in politically rigid countries communicating with whistleblowers and dissidents. Law enforcement officers on Internet sting operations stay anonymous with Tor, as do people wanting to post socially sensitive information in chat rooms, like rape or abuse survivors and those with illnesses.  The Tor network also provides protection for people looking for another layer of privacy from the millions of websites and ISPs bent on collecting private information and tracking their moves online.


Based in Walpole, MA, The Tor Project develops free and open-source software that provides online anonymity to the everyday Internet user. Tor was born out of a collaboration with the U.S. Naval Research Lab starting in 2001, and it became an official U.S. 501(c)(3) non-profit in 2006. The Tor Project now works with many individuals, NGOs, law enforcement agencies, and businesses globally to help them protect their anonymity online.

In addition to its efforts developing and maintaining the Tor anonymity software and the Tor network, The Tor Project also helps to lead the research community in understanding how to build and measure scalable and secure anonymity networks. The Tor developers publish several new research papers each year in major academic security conferences, and just about every major security conference these days includes a Tor-related paper. Tor is a project-funded organization with a staff of 15.
