BitLocker and MBAM serve complementary roles in managing disk encryption for Windows devices: - BitLocker is a built-in Windows feature that provides full-disk encryption to protect data on your computer or removable drives. - MBAM is a management tool by Microsoft that complements BitLocker. It offers centralized management, reporting, and key recovery features for BitLocker. If you need centralized management, compliance reporting, and enhanced key recovery capabilities for a larger number of devices in an enterprise setting, implementing MBAM alongside BitLocker is advisable.
