End-to-end efficient encryption prevents unauthorized access to sensitive data that is in flight from a host application, or data at rest within the PowerMax safe. This solution brings together encryption from Thales (using Vormetric transparent encryption with data security external key management) and PowerMax Data at Rest Encryption with easy-to-manage internal key management. Incorporating both encryption technologies allows you to take advantage of the space-saving data reduction while ensuring that all sensitive data is secure.
