A lawsuit filed by Self-Help Credit Union alleges that Fiserv misled its clients about security measures, particularly regarding two-factor authentication. The credit union claims that Fiserv represented it was implementing this security protocol while actually relying on less secure methods, such as email passcodes for accessing sensitive information. The attorney for Self-Help, Charles Nerko, emphasized a significant discrepancy between what Fiserv promised and what it delivered. The credit union is seeking restitution for fees it paid under the assumption that enhanced security was in place. Fiserv has pushed back against these claims, stating it will vigorously defend itself in court. Despite having an agreement with Self-Help for stringent security protocols, the complaint suggests Fiserv's actual practices fell short. This lawsuit is part of a broader trend; Fiserv has faced multiple shareholder lawsuits in recent months, with allegations that it failed to disclose critical information about its operations and misled shareholders regarding the transition to its Clover point-of-sale system. Following a disappointing second quarter earnings report in July, Fiserv's stock has suffered. In response, the company has made executive changes and is trying to reassure stakeholders about its direction. CEO Mike Lyons denied accusations of coercively moving clients to Clover during a recent technology conference, asserting that clients will not be forced to switch from their current systems.
