How do Chromebooks manage to protect themselves so well? To begin, the Chrome OS is based on the Linux OS, one of the most secure operating systems out there. Linux is open-source, which means that anyone can contribute to its development. More people working on it raises the chances that bugs will be caught and fixed before they become problems. By using Linux as a template, Chrome ensures that it has the strongest securi1ty of any operating system on the market. With that said, we still recommend using one of the best antivirus software for Linux on any device running the Linux operating system since it still has some vulnerabilities.
