Enterprise Vault security and encryption

Hi People,

What is the latest security feature that Enterprise Vault 10.0.3 can handle ?

I have googled around and found this long closed article https://www-secure.symantec.com/connect/forums/encrypt-enterprise-vault-data which doesn't convince my Security manager which enforce me to secure and encrypt the Symantec Enterprise Vault data.

this document Enterprise Vault and FIPS 140-2.pdf doesn't actually says that it is encrypting the content of the VaultStore on the fly for the latest version of EV 10.0.3
