Symantec Encryption products enable you to encrypt and decrypt content automatically and on-the-fly so that effort is minimized during these operations. When automatic options are not possible, such as when email disclaimers are added to the encrypted content, causing the content to no longer appear encrypted, then we have some manual methods to be able to decrypt the content.
