Tor browser is a free software that helps you defend against any form of surveillance that threatens individual liberties, privacy, as well as business and confidential relations. Since any sending or browsing goes through a connection between computers through encrypted links, it will be impossible to locate you through Tor USB. Indeed, this software prevents anyone from observing your Internet connection, to know which sites you visit. It even prevents the site you visit from knowing where you are. Therefore, your navigation will be safe. This software also allows you to send your mails confidentially because it uses an encrypted channel. This makes impossible any attempt of diversion by a third party. Thus, this software is an indispensable tool if you doubt the confidentiality of mails or important files that you must send. In addition, even when opening a folder on the PC, your system administrator or others will have no remote access to it. Being portable, there will be no installation to do. It can even work on a USB key.
