Encryption Question CRM

Encryption Question CRM

Hi Folks! Are the data in CRM encrypted at rest? Or are only the fields marked Encryption encrypted at rest? 

And if not, I understand there is full disk encryption available for certain data centre, I believe mine is in the US data centre, will I be able to request for full disk encryption? 


Additional information, I am in the financial services space, so I'll need a lot of personal data to be encrypted
