Qubes OS - A Reasonably Secure Operating System
https://www.qubes-os.org/

Qubes is a security-oriented operating system (OS). The OS is the software which runs all the other programs on a computer. Some examples of popular OSes are Microsoft Windows, Mac OS X, Android, and iOS. Qubes is free and open-source software (FOSS). This means that everyone is free to use, copy, and change the software in any way. It also means that the source code is openly available so others can contribute to and audit it. Qubes takes an approach called security by compartmentalization, which allows you to compartmentalize the various parts of your digital life into securely isolated virtual machines (VMs). A VM is basically a simulated computer with its own OS which runs as software on your physical computer. You can think of a VM as a computer within a computer. This approach allows you to keep the different things you do on your computer securely separated from each other in isolated VMs so that one VM getting compromised won’t affect the others. For example, you might have one VM for visiting untrusted websites and a different VM for doing online banking. This way, if your untrusted browsing VM gets compromised by a malware-laden website, your online banking activities won’t be at risk. Similarly, if you’re concerned about malicious email attachments, Qubes can make it so that every attachment gets opened in its own single-use, “disposable” VM. In this way, Qubes allows you to do everything on the same physical computer without having to worry about a single successful cyberattack taking down your entire digital life.
