Internet privacy has become an increasingly important issue over the past decade, and most people now understand that websites, businesses, and other entities can easily track and aggregate your personal information while you're online. Some people don't seem to mind this. But a growing number of businesses, activists, journalists, educators, and others are turning to Tor and tools like it to keep their locations, browsing habits, and IP addresses secret. Users may like to start by reading the section on the Tor website entitled, "Want Tor to really work?" This explains how to get the most out of the Tor browsing experience, which can be used with both Mac or Windows devices. Readers looking for more online privacy will find much to appreciate in this easily downloadable anonymity network.
