UPDATE from Gainsight 10/16/15: 





Zendesk security issues have been resolved and it is live again! The new version is available on the internal Zendesk App marketplace and will be available on the public site in the next day or so.





Please note that you MUST be on Gainsight V 4.33.1 to deploy the integration. This version was automatically pushed to all customers yesterday who have not opted out of Gainsight automatic upgrades.

----





From 10/3/15: If you installed our Zendesk integration app, we recommend that you uninstall it, or hold off on installing it, until we fix a security issue. 





We have a security issue in our Zendesk connector that we released this month. The issue is that once a Gainsight user authorizes MDA and then enables Zendesk integration, any user/agent in Zendesk is automatically logged into SFDC as the user who has authorized MDA. Agents can gain this unintended access only via the Gainsight app in Zendesk. Therefore, we recommend customers uninstall the app from their Zendesk Sub-domain (or hold off from installing our app) until we provide a fix and publish an updated version of the app. If you have enabled syncing of Gainsight and Zendesk data, disable the sync.
