Qubes OS

Qubes OS is a security-focused operating system that isolates different tasks into separate "virtual containers" called qubes. This compartmentalization ensures that if one part is compromised—like browsing a risky website—other parts, such as your personal files or banking information, remain protected. It uses virtualization technology to run these isolated environments simultaneously on a single computer. This approach enhances security without sacrificing usability, making it suitable for users who require strong privacy and protection while conducting everyday activities.
