Why one would use Qubes OS? (2023)

Qubes OS is a security-focused operating system that utilizes virtualization to compartmentalize applications and tasks, enhancing privacy and security. It operates on a minimal XFCE interface within a domain called dom0, from which users can launch virtual machines (qubes) that run various applications. Each qube can be configured to use different templates, such as Debian or Fedora, and can be set to discard changes upon reboot, ensuring a clean state. The system includes specialized qubes for network management (sys-net and sys-firewall) and USB device handling (sys-usb), allowing for secure and controlled access to external devices. While Qubes OS offers significant advantages in security, such as efficient VM management, disposable VMs, and integration with Tor, it also has drawbacks, including limited hardware support, high resource requirements, and a steep learning curve. It is particularly beneficial for users who need to run untrusted software or maintain strict separation between different tasks and data. However, it is not suitable for multimedia tasks or gaming due to the lack of GPU acceleration. Overall, Qubes OS is designed for users who prioritize security and are willing to invest time in learning its complexities.
