Sorry for asking, but what will they gain from this? If the laptop is
stolen, are they aware of the fact that unless it's encrypted with
BitLocker, it's most likely that the content of e:\data will be stolen as
well? Are they using some sort of Smart Cards or other method of
authentication?

Unless something really sophisticated is going on that we're not aware of,
I'd suggest that you review your requirements, and that you ask a good
security expert to help you design your security solutions.

Daniel is correct. Until you can define which threats you want to mitigate,
then you really can't design an appropriate encryption process.

Hi,
We have more than 10.000 clients and the idea is to migrate to Vista in
2010, so that we can use bitlocker. Meantime management request that we
protect the data on our laptops, against data lost and if possible encrypted
and without spending money...
Therefore I is was thinking to implement EFS but then users should not have
the option to decrypt files...

What kind of data loss? Do you mean theft of a laptop? If so, then BitLocker
is better suited to this, so perhaps you can accelerate your upgrade plans.

Properly configured, EFS can also be used to mitigate this threat, but it's
more work. Follow the guidance in the Data Encryption Toolkit for Mobile PCs
(search our web site for it).
