Reference guide for GAME

This guide is intended to help you purchase, set up, and test your G Suite Message Encryption (GAME) service for production use. GAME is an email encryption service for G Suite customers. Designed by ZixCorp at the request of Google, GAME provides secure email to G Suite users communicating outside Google’s secure cloud to all other email users.

Note: The Google Cloud Support team provides limited support for GAME, as it is a third-party service.

Get started

Learn about GAME International

GAME provides on-demand message encryption, so you can securely communicate with business partners and customers. G Suite customers can predefine security policies to trigger encryption of sensitive information in their outbound email communication. Using ZixCorp’s Best Method of Delivery, GAME provides transparent encryption between G Suite and ZixCorp customers, as well as the ability to deliver securely to anyone, anywhere and on any device. For additional information on ZixCorp's G Suite Message Encryption service, visit the GAME Resource Center.

Purchase GAME

Your first step in setting up GAME is to purchase it by contacting a Google sales representative or Google Cloud partner directly. Your order is then forwarded to ZixCorp, who is accountable for facilitating your GAME service set up. In addition, after purchase, you must also take some steps to complete your set up. See Service setup overview for details.

Understand setup tasks

After purchase, you must complete your GAME set up by doing the following, in this order:

Note: You must have Super Admin privileges in G Suite to complete many of the tasks described here. If you are the primary user who set up the original G Suite account, you are the Super Admin by default. The primary G Suite administrator must grant subsequent users Super Admin privileges.
  1. Choose your GAME configuration options using the GAME Self-Service portal. See Set up service using the GAME Self-Service Portal.
  2. Enable the Admin SDK within G Suite to allow the GAME Admin Tool to authenticate you. See Enable the Admin SDK.
  3. Set up authorized message encryption users and create custom email bounce messages in the GAME Admin Tool. See Set up the GAME Admin Tool.
  4. Configure the Google Admin console to route encrypted email properly. See Set up the Google Admin console for encrypted mail.
  5. Test your GAME service to ensure it is sending encrypted email properly. See Test your GAME configuration.
Set up GAME using the Self-Service Portal

Once you have purchased GAME by contacting and working with a Google sales representative, ZixCorp receives your order request and sets up your GAME Self-Service Portal (SSP) account information. The GAME SSP automatically sends you a welcome letter to help you get started. You must then choose your GAME configuration options using the GAME SSP.

Note: You must choose your configuration options using the GAME SSP and submit your service for deployment before continuing with the next step.

When you receive the automated welcome letter from the GAME SSP, follow the instructions in it to sign in to the GAME SSP to prepare and submit your service for deployment. Service deployments happen every Tuesday and Thursday night:

  • Deadline for Tuesday night deployment—Submit your GAME SSP order by the previous Wednesday at 5pm EST.
  • Deadline for Thursday night deployment—Submit your GAME SSP order by the previous Monday at 5pm EST.

After you choose your configuration options using the GAME SSP and submit your service for deployment, ZixCorp deploys the service. After that, you receive a confirmation email. Once you receive confirmation that your GAME service is deployed, you must then change some settings for the GAME service.

Set up and launch the GAME Admin Tool

Learn about the GAME Admin Tool

The GAME Admin Tool allows you to add authorized message encryption users and to set up custom email bounce messages that are sent to unauthorized users.

When a G Suite user need to send an encrypted email, that message is routed to the GAME SMTP server, which then checks the sender’s email address against the authorized message encryption users list you created.

If the user is authorized to send encrypted email, the message will be encrypted and sent using ZixCorp’s Best Method of Delivery (BMOD). BMOD provides transparent encryption between all ZixCorp customers as well as two different keyless delivery methods for other recipients. The default keyless delivery method for GAME customers is Portal Delivery.

Note: The GAME Admin Tool is intended to manage only your primary Google Admin console domain. Any users in additional domains are automatically allowed to send encrypted email. If you want to change these permissions, you must manage them using content compliance rules in the Google Admin console.
