BitLocker encryption was introduced with Windows Vista, but has been enhanced with Windows 7.
The rise in laptop usage and roaming/remote workers means that terabytes of sensitive information are potentially wandering the street at any given moment. Laptops are easily lost or stolen and steps need to be taken to protect the data they contain.
BitLocker provides the ability to encrypt all of the data on the drive and ensure that it can not be compromised even if the laptop falls into the wrong hands. Windows 7 extends the BitLocker protection to USB thumb drives and removable storage as well.
