I've been using FilveVault for a while now, and while I don't have any complaints with regards to performance for functionality, but I am running into a problem now. I want to start using Time Machine, but it doesn't back up from a File Vault volume. You have to log out and let it back up the sparse image, which doesn't help me much (I have a backup solution for that already).

So what's left is full disk encryption. I have found three solutions that look promising:

PGP Whole Disk Encryption
Winmagic SecureDoc Disk Encryption
Check Point Full Disk Encryption

Does anyone have any real-world experience with either on these on a Mac? PGP I have plenty of colleagues using on Windows, but that doesn't mean anything.

I'm particularly interest in SecureDoc for offering support for Seagate's FDE drives - it's the only way I know of to use those with a Mac.

Thanks
 
I used PGP WDE for about 18 months, no issues at all.

However, they did not have support for Snow Leopard for a while so I uninstalled it. However I see now that there is a newer version of PGP WDE which does support Snow Leopard so I will probably go back to using it.

Our company uses PGP for email and documents so it was a bonus to be able to use the WDE on laptops as well.

Hi Duckie, what hardware did you use it on? Did you notice any performance hit? How much? The guys at work (Mostly Dell laptops with Windows XP or newer) complains about sluggishness with PGP.

Thanks
 
MacBook Pro 15" late 2007, 2.2GHz Core 2 Duo, 4GB RAM.

I can't say that I noticed any slowdowns. Bear in mind that the PGP solution uses (from what I can gather) some pretty low-level disk drivers so I would think that the performance hit is minimal (the drivers load before the OS does).

Cool! Is this with a Seagate FDE drive? Or the stock whatever came with it? I haven't been able to find out if the TPM chip merely keeps apple's keys or if it can actually be used for hardware encryption/decryption.
