Due to the TriZetto Healthcare data breach, Cognizant is being sued in the US
Cognizant Faces Multiple Class Action Lawsuits After TriZetto Data Breach
US-listed IT services firm Cognizant Technology Solutions Corp is facing multiple class action lawsuits following a data breach at its healthcare claims processing subsidiary, TriZetto Provider Solutions (TPS), according to court filings.
At least four class action lawsuits were filed in December in US district courts for the District of New Jersey and the Eastern District of Missouri, alleging that TriZetto failed to adequately safeguard sensitive personal and health information and did not notify affected individuals in a timely manner after the cyberattack.
One of the complaints, filed on December 17, 2025, alleges that TPS failed to properly secure and protect sensitive data belonging to current and former patients, including protected health information (PHI) and personally identifiable information (PII). “Plaintiff brings this class action against Defendant for its failure to properly secure and safeguard Plaintiff’s and other similarly situated patients’ sensitive information,” the filing stated.
According to the complaints, the compromised data may include names, addresses, dates of birth, Social Security numbers, health insurance member numbers, insurer details, beneficiary information, and other demographic and health insurance data.
Court documents allege that an unauthorised third party breached TriZetto’s network in or around November 2024, but the company did not detect the intrusion until October 2, 2025, nearly a year later. After engaging an external cybersecurity vendor, TriZetto concluded that patient and insured persons’ private information had been exposed, according to a complaint filed on December 23, 2025.
The lawsuits claim that more than 100 individuals across multiple US states were affected by the breach. One complaint filed on December 19, 2025, estimates damages exceeding $5 million, exclusive of interest and legal costs.
In a statement, a Cognizant spokesperson said: “TPS takes the protection of information very seriously and regrets any inconvenience this incident may have caused. Because this matter involves ongoing litigation, we are unable to provide further comment at this time.”
Cognizant acquired TriZetto in 2014 to strengthen its healthcare IT services portfolio. The lawsuits add to growing scrutiny of data security practices among healthcare technology providers handling sensitive patient information.
