Zobst Storage Manager provides a robust application-level AES-CBC 256-bit encryption capability that your data deservers and your customers demand.  Array based encryption at rest can still be utilized, but the Zobst encryption provides additional capabilities that are vital for your business:

• Compatible with Zobst compression, so you can still save capacity while enabling encryption.
• Supported for both block and object storage.
• Ability to set different encryption keys per Zimbra mailstore, so that you have flexibility on when to offer encryption and ability to segregate keys.
• Key rotation is supported
• Re-key mail messages when needed, transparently to the end-user and without overwhelming either Zimbra mailstore server or the storage subsystem.
• Flexible implementation to allow seamless support for additional ciphers
