[FDE] Intro and EFS as a viable FDE solution?

[Mike Johnson]

Howdy all,

Just found this list while looking for information about full disk 
encryption for an enterprise.  We're approaching it as a two phase 
implementation, where the first phase may be tossed.  We have a 
short-term need (mandate) to implement encryption on a few (about fifty) 
sensitive laptops.  Long term, we want all our laptops encrypted.

We're looking at EFS because, well, it's free.  We've been doing 
research on it, its limitations and its weaknesses.  Some of the 
weaknesses seem to go away once you implement it on domain resident 
systems.  EFS may simply be a short term solution for us, but we're not 
sure how it'll scale/work across several thousand laptops.

Has anyone on this list done FDE on a large scale?

Oh, and, howdy. :)

Thanks!
Mike
