What is a pre-boot operating system, and why is it important?
A pre-boot operating system is a small, fast, secure environment that hosts user authentication for GuardianEdge Hard Disk Encryption endpoints. This pre-boot operating system is hardened to protect against security exploits, with entry points rigidly defined to create a very small attack surface relative to the endpoint’s main operating system. It provides a highly secure environment for user authentication with features like automatic delay after a pre-defined number of incorrect password attempts, and supports user productivity with features like single sign-on to Windows.
