Linux

Yea that's a bit limites of a description. Tails is an OS you can run from a USB stick. It doesn't keep data so when you reboot it's like a fresh install. This makes it popular among people who buy/sell illicit goods, but it's also very useful if you're not in a safe location and don't want your computer to incriminate you. Utilizing this with a VPN is one of the best ways to limit your digital footprint and tracking. It's also highly inconvenient for day to day use, but when utilized properly it is one of the best options.

I remember reading an article this year about a drug ring that got caught and shutdown because one of the leaders didn't follow protocol and used a personal device to send a message. Now while I'm not advocating that kind of usage of this tool, I do believe it speaks volumes as to it being secure as this ring had existed for years prior.
