8. Qubes OS: Security-by-Isolation OS

Qubes OS is based on Xen, X Window System and Linux. It provides hardened security using the security-by-isolation approach, creating many security domains, which are implemented as lightweight Virtual Machines (VMs). These domains have their own set of security restrictions, isolating one domain from the next.

So if you separate your browser from your sensitive work data, a hacker or malware would not be able to access your information even if it has compromised your browser, thanks to the isolated domains and strategic compartmentalization. That’s the beauty of the security implementation of Qubes OS.
