I need to encrypt Windows VMs in a VMware environment at a host level. BitLocker is out as it's not supported by VMware. PGP appears to be problematic. TrueCrypt supports Windows Server 2003 and 2008 but not 2012, so that's problematic, but looks to be the best option so far. I can't encrypt at the hypervisor or storage layer.
Any suggestions as to what host-based encryption tool i can use that's fully supported in a VMware environment?
