The most secure OS to date. Everything on it is another virtual mission practically sandboxes from everything else. Open a browser in one VM, a text editor in another and you have to do quite a bit to cut and paste to the other. Hacker gains control of browser but can’t access any other part of machine. If any portion is compromised you just close it and spin up another. Requires significant time to get spun up on using it but then you are a pro after reading all their materials.
