BitLocker is a full-disk encryption feature built into Windows. It encrypts data per volume and stores the key in the TPM chip so the drive can be unlocked automatically during boot, and it can be configured to additionally require a PIN, a USB key, or a recovery key. Like LUKS on Linux and FileVault on macOS, it belongs to the data-at-rest encryption category.
