As part of the remediation effort, we completed the task of deactivating S3 connections for customers whose S3 access keys have not been rotated since before January 2025.
On December 4th, between 6:00 AM - 9:00 AM PT, we will deactivate S3 connections for customers whose S3 access keys have not been rotated since before January 2025 as part of the remediation effort.
All customers using Google SSO OAuth, are strongly advised to complete the steps in the FAQ item item “My Google SSO login into Gainsight is failing. What can I do?”— even if access to Gainsight is still functioning—to move to SAML based authentication.
In addition, updated guidance is available for re-authenticating the GS Assist Gmail plugin and Gmail calendar integration, if you are running into issues with these features.
Google SSO logins (Gsuite) are currently failing for small subset of customers who use Google OAuth to sign into Gainsight. To ensure uninterrupted access, we would like to propose an alternative approach using SAML authentication. We support SAML setup with any Identity Provider, including Azure, OneLogin and Google. Our team will be happy to guide you through this configuration. Please see the question “My Google SSO login into Gainsight is failing. What can I do?” in our FAQ for more info - https://communities.gainsight.com/community-news-2/salesforce-security-advisory-relating-to-gainsight-faqs-29809

We want to provide more information on the issue we shared earlier today. We have engaged Mandiant, a leader in cybersecurity, to assist us in our comprehensive, independent forensic investigation.
Our current findings indicate that the activity under investigation originated from the applications’ external connection — not from any issue or vulnerability within the Salesforce platform. Salesforce has independently notified known affected customers and continues to investigate.
We are committed to keeping you informed, and we appreciate your patience and partnership
