Best Full Disk Encryption for Windows Laptops - AES 256 and Single Sign on

Hi there,

I am currently on the lookout for a Full Disk Encryption product.

We are currently using CheckPoint but it does not work well with AHCI mmode and causes BSOD.

I am looking for an alternative product with the following minimum specs:

1. AES 256 or higher

2. Single sign on(Windows integrated logon) for better user exp.

3. Easy management for sys admins.

4. Compatible with Windows 7(AHCI)

It need not be freeware.

If anyone has suggestions then please reply.

Thanks,

Sanket
