# Overview

FileVault is macOS's built-in full-disk encryption feature, protecting data at rest so it cannot be read if a device is lost or stolen. This section covers what FileVault is, how to enable it during the Setup Assistant with Intune, and the insights you need to manage encryption and recovery keys in production. It is aimed at IT administrators responsible for endpoint security and compliance on macOS.

Begin with the overview, then follow the setup guide and review the field insights.
