PGP Whole Disk Encryption.   Nothing homebrew ;-)

Chris,

Are you using PGP and keys, or just PGP Disk? If the former, I'd be interested to know how you handle keys.

there are lots of edge cases with hardware capabilities.

I'm ignorant on it now so please raise any concerns with your sales/tech representatives.  Deployment wise, it seemed 
very nice.   However, it was implemented as a filesystem driver so when it wrote to disk, it would encrypt the contents 
of the files.

E.g   Students\BobbyTables-SSN.pdf  would still have a visible filename even if the content was encrypted.   That's a 
great reduction but implementing an encryption solution is a lot of work if you still end up with "disclosure due to 
loss" scenarios on assets you've touched.  I believe they added a feature to change that.   This wasn't an obvious 
scenario until we started discussing "how to do windows troubleshooting".

Hello,

We're on a fast growing campus here at the University of Washington Bothell.  We're in the initial stages of exploring 
encryption and I was wondering if anyone out there had any thoughts or suggestions on this topic?

So far we're looking at using BitLocker and maybe EFS.  We're also looking at Dell's Data Protection Solution.

Thanks!
Will
