Over the last several years, we have been increasing data security and making every effort to better secure our client data, particularly PII.  As a result, we are to the point where we are evaluating the need to encrypt the data on all of our branch office servers, which includes both Exchange and files shares.  
 
We are interested in finding out if any of you are encrypting your server data and if so, how are you accomplishing it?  Has anyone used EFS on file shares and Exchange and if so, what are the performance implications?  Has anyone used self encrypting drives and have you had any issues or performance implications with them?

Hi,

If you're running Server 2008 you have the option of BitLocker encryption - this protects the drive when powered down:

The Best Idea is to establish VPN Connection between the physical locations for security
so if you can send me the network diagram for the whole offices so I can give you the best design to your network .
also is there any routers, firewalls are used or you just use windows servers?

I'm not interested in data in transit, I have that covered.  I am interested in data at rest or mitigating against something like a server being stolen, etc.

Hi,

Perhaps you should consider a 3rd party data at rest solution that's compatible with any RAID configuration you have. Ideally, 3 factor authentication should be used - e.g. TPM, USB and PIN or USB key, PIN and password.

That way if the server is stolen, nobody can start it or access data on the drives as they are in an encrypted state.

Go for a commerical tool with FIPS validated encryption.

Regards.

We believe of all the options available Self Encrypting Drives will be the best solution. Thx all.
