Check Point Full Disk Encryption.
Does whole disks only, will not do partitions or RAID Volumes.
Is what was PointSec PC but rebranded since Check Point purchased PointSec. Is now part of the Check Point End Point Security Suite.
Just don't use it with Dell Laptops as forums full of issues with different dell machines, either bios upgrades or settings need changing.
PGP were pointing us to their Universal Server product with Full Disk Encryption which works with AD etc etc.
As always costs is an issue!
Never realised true crypt does full disk encryption. According to the website it does container based encryption.
website said:Main Features:
* Creates a virtual encrypted disk within a file and mounts it as a real disk.
* Encrypts an entire partition or storage device such as USB flash drive or hard drive.
* Encrypts a partition or drive where Windows is installed (pre-boot authentication).
