Cognizant Technology Solutions Corp. is facing mounting legal pressure in the United States as class-action lawsuits accuse the company of failing to promptly disclose a major cyber intrusion tied to its healthcare subsidiary, TriZetto — a lapse plaintiffs say left sensitive personal data exposed for months.
At the heart of the dispute is the cognizant trizetto data breach, which attorneys argue unfolded quietly, like a slow-burning fuse, before erupting into litigation late last year.
Alleged Breach Went Unreported for Nearly a Year
According to court filings, hackers infiltrated Cognizant’s computer network and gained access to protected private information handled by TriZetto, a healthcare claims processing unit. The breach allegedly began around November 2024, but Cognizant says it did not discover the unauthorized access until Oct. 2, 2025 — nearly a year later.
Plaintiffs including Liam Lytle, Maricruz Jimenez, and Carson Noel claim the breach affected at least 100 people across multiple U.S. states, exposing data such as Social Security numbers, financial account details, and home addresses.
The lawsuits contend that Cognizant and TriZetto either knew or should have known about the intrusion far earlier and failed to alert victims in time to protect themselves from identity theft and fraud.
