Hello Folks,

I do healthcare IT and I have a client to wants my advice in encrypting a server small medical office. To me,  email encryption of server seems like a bad idea due to reliability issues that I've seen in the past with encrypted drives.  I just wanted to get some advice from some of you folks who may have had real in the trenches experience with email encryption on servers.  For  anyone has experience, I have the following questions:

1.  Does email encryption decrease the reliability in general of the server storage array?
2.  Does it decrease the performance  throughput to the drives?
3.  What do you do if you need to remotely reboot the server and you don't have an HP ILO or similar device to log into the encryption software before the OS boots?
4.  Is encrypting a server worth the potential drawbacks  and if not, are there any alternatives you might recommend?

Thanks!

1) It depends on how you encrypt, but a trustworthy solution will not inherently decrease reliability

2) There will always be a performance hit. Some products are slight, some are more noticeable. But yes, performance will be impacted. Plan accordingly.

3) Choose an encryption that does not require this.

4) For some environments, yes.

Personally, I'd go with Bitlocker. It is fully supported with Exchange. The performance hit is minimal. And it can be configured to automatically unlock with a TPM module. So data at rest is secure and cannot be read if drives are removed, but servicing and reboots are transparent. Plus AD can hold backup keys.
