Lawsuits over TriZetto data breach filed against Cognizant

Cognizant Technology Solutions has been accused of failing to properly secure sensitive healthcare data and waiting nearly a year to notify affected individuals in the multiple US class-action lawsuits filed following a data breach at its TriZetto Provider Solutions subsidiary, reports GBHackers News.

The lawsuits allege that hackers accessed TriZetto's systems as early as November 2024, but the intrusion was not discovered until Oct. 2, 2025. Court filings claim that sensitive information, including Social Security numbers, home addresses, and financial account details, may have been exposed for about 11 months. Plaintiffs from states such as Arizona and California accuse Cognizant and TriZetto of negligence and failing to implement adequate security measures. The complaints also fault the company for delaying notification after discovering the breach.

According to CNBC, legal filings argue that this delay prevented victims from taking steps to reduce the risk of identity theft and fraud. Plaintiffs further cite limited public information about the cause of the breach and the actions taken afterward. TriZetto said it "takes the protection of information very seriously" and declined further comment because of the ongoing cases.
