Its becoming more and more important to provide Encryption to clients. Sure if you have a small amount of computers you could use TrueCrypt or another alternative.
If you have all new Windows 7 Machines with Ultimate or Enterprise with a TPM chip you could utilize bitlocker. But alas not all users run Windows 7. (still trying to figure out the cost of Microsoft Bitlocker Administration)
Third party Software Vendor that offers the "suite" including anti-virus, encryption, email plugins etc etc.
If you had 40 Devices you could easily be looking at 4grand or so for 1-2 year subscriptions
Maybe a SAAS or CloudBased like TrustWave or someone similar.
What do you guys use? How do you manage it (Specifically what software)
Im interested in hearing what you guys have to say.
