You can run this OS of a thumb drive on almost any computer without actually installing the operating system.

It feels safer and more privacy orientated than other Operating Systems, and I am in control of my own personal data.

Tails is hands down the best Operating System if you are worried about Security. It's built on Linux and comes with everything you need to get up and running on the latest SecOPs Tools; Its literally plug and play. Download it; Check the SHA Sum; Burn it to a USB drive; and boot from the drive. It will walk you through everything you need and you literally will be covered. It automatically connects you to TOR, so you don't need to know anything to have NSA level Security
