Qubes OS A reasonably secure operating system

What the experts are saying

"If you're serious about security, Qubes OS is the best OS available today. It's what I use, and free."
Edward Snowden, whistleblower and privacy advocate

"Happy thought of the day: An attacker who merely finds a browser bug can't listen to my microphone except when I've told Qubes to enable it."
Daniel J. Bernstein, mathematician, cryptologist, and computer scientist

"When I use Qubes I feel like a god. Software thinks that it's in control, that it can do what it wants? It can't. I'm in control."
Micah Lee, Freedom of the Press Foundation, The Intercept

"Donated a % of my consulting company's last year revenue to Qubes OS. I rely on it for all my work, and recommend it to clients too."
