You don’t need to be IT expert to secure your computer

 Developed by Air Force Research Laboratory's Information Directorate, of the United States Air Force. TENS is a thin Linux operating system optimized for maximum security, confidentiality and privacy. It boots from an USB flash drive without mounting a local hard drive and doesn’t require any administrator privileges; nothing is installed. Because the environment runs entirely without hard drives, nothing malicious already on a local drive can infect your running session, and nothing sensitive from the secure session can be left behind on a hard drive. TENS creates a secure computing environment which can run on almost any Intel-based computer.

Malware free

As TENS boots from a USB Flash drive without mounting the internal hard drive, no malicious malwares (virus, trojan, keylogger...) can affect your running session because no local hard drive is mounted, no persistent user session data is saved. Each time you reboot TENS, you have a new clean and secure session.

charis.ma - Secure from hackers

Secure from hackers

TENS is more secure than most operating systems since it is designed to run from USB flash drive with no persistent storage. You can browse securely the Internet without leaving traces of Internet transactions, browser history, personal data, or sensitive information on the host computer. So no cyber-thieves or hackers can steal your sensitive data, and gain backdoor access to your system.
