 The recent court battle between Apple and the FBI, along with a slew of major security breaches from Experian to Ashley Madison, have popularized encryption as a way to protect messages, yet email encryption is also reported to be difficult to use for people unfamiliar with the encryption process.To simplify the encryption process, Zix email encryption uses an e-mail encryption directory called ZixDirectory that lists other email addresses protected by the encryption service to maintain a community of users who can send and receive e-mails to each other without having to use encryption keys.Customers install a ZixGateway application and configure compliance and security policy requirements, then the application monitors outbound emails to determine whether messages should be encrypted, and then works in conjunction with secure servers in a SaaS (software-as-a-service) environment to encrypt outgoing communications and securely decrypt inbound messages from other users listed within the ZixDirectory.
