Seamless enterprise level email encryption with gateway scanning

ZixGateway is a policy-based email encryption appliance that sits on the edge of your network and monitors all outbound email for sensitive information. With full content scanning of the subject line, message body and attachments, ZixGateway can encrypt, route, block or brand outbound email based on corporate policies. It automatically strengthens compliance for email communication without requiring any special training or crazy procedures for your team.


Easy to use automation

ZixGateway automates the most complicated and expensive part of email encryption – management of the different keys. With ZixGateway, all key management is handled through ZixDirectory, the world’s largest public key repository with tens of millions of members. ZixDirectory also safeguards against expired keys and certificates by providing centralized distribution among all members.

ZixGateway scanning

For many healthcare organizations, safeguarding email sent by its employees is not enough. ZixGateway offers that insight and provides a way for healthcare organizations to better manage their compliance with the Health Information Technology for Economic and Clinical Health (HITECH) Act and the Health Insurance Portability and Accountability Act of 1996 (HIPAA). When vulnerabilities are identified, both the appropriate internal compliance manager and the business associate can be automatically notified.

Painless email encryption – delivered to anyone!


Just as ZixGateway automatically scans email, it also automatically determines the most efficient way to securely deliver messages using the ZixCorp Best Method of Delivery. Through the Best Method of Delivery, ZixGateway delivers encrypted email to anyone, anywhere and often transparently.

ZixGateway offers the industry’s only bidirectional transparent email encryption, enabling senders and recipients to exchange encrypted email without any extra steps. When a ZixGateway customer sends encrypted email to another ZixGateway customer, the message and replies are delivered securely and transparently, so that not even a password is needed. On average, more than one-third of our customers’ recipients receive their encrypted email messages transparently.

Superior Support for TLS


ZixGateway is unique in its support for TLS in several ways. ZixGateway simplifies the set up of TLS configurations by making it a part of the email encryption policies. This makes enabling TLS as easy as selecting it as one of the delivery methods. By including TLS in the policy, compliance and security officers also have increased control of and visibility into how sensitive data is delivered.Recipients who support the appropriate level of TLS, receive secure email transparently, further enhancing ease of use. No matter the recipient, ZixGateway ensures all replies are encrypted – a guarantee not delivered in standard TLS solutions.

Flexible Delivery


For recipients who do not have email encryption capabilities, ZixGateway offers two different delivery methods – ZixPort and ZixDirect™. ZixPort is a pull technology that provides a secure portal for delivering sensitive information to customers and partners. It can be branded and integrated into your corporate portal. ZixDirect is a push technology that delivers encrypted email directly to user inboxes. All of these options combine to create the ZixCorp Best Method of Delivery, which automatically determines the most secure and transparent method of sending your message.

State-of-the-Art Reporting Dashboard


ZixGateway also offers superior “at a glance” usability for compliance and security officers through an easy to customize reporting dashboard. Able to run more than 25 different reports, the dashboard provides immediate access to important information about inbound and outbound message data, including what policies were triggered, what delivery method was used, number of blocked messages, and top senders and receivers.
