Marshall Community Credit Union (MCCU) filed suit against Fiserv Solutions and Fiserv Inc. on October 5 in the U.S. District Court for the Western District of Michigan. The federal docket confirms the new case, Marshall Community Credit Union v. Fiserv Solutions, LLC, No. 1:26-cv-02858
MCCU alleges that several Fiserv systems lack adequate security controls, including insufficient multifactor authentication, and says it experienced numerous outages and service disruptions. According to the complaint, MCCU submitted more than 280 support tickets from the beginning of 2025 through roughly July 2026, including alleged outages involving SecureNow, Corillian and Portico. MCCU is also challenging what it says could be seven-figure termination/deconversion charges if it leaves Fiserv. Fiserv previously denied to MCCU that it had breached their agreement. These remain allegations and have not been adjudicated
