Over the weekend, Medallia received notification about a series of security concerns from Citrix, a well-established vendor used by Medallia for network load balancing.  As a precautionary measure to protect our systems and client data, Medallia reacted immediately to temporarily restrict access to affected environments at approximately 10:30 am PT while deploying the necessary updates. Medallia restored service to data centers on a rolling basis over the following hours.

Based on our investigation and monitoring to date, we have identified no evidence that client data was accessed or compromised as a result of these vulnerabilities. Medallia continues to monitor its environments and evaluate relevant guidance from Citrix as it becomes available.

Services in your environment have now been restored. As a result of the interruption, your IT teams may need to restart or retrigger  integrations or data transfers with Medallia.  Please open a ticket with Medallia Support at help.medallia.com if you have any questions or concerns.

For further details about the Citrix notification, please see https://www.cisa.gov/news-events/alerts/2026/09/27/critical-zero-day-vulnerabilities-exploited-citrix-netscaler-adc-gateway.

We appreciate your patience and understanding, and apologize for the disruption this may have caused to your organization.

Medallia Support
