Cognizant Hit With Multiple US Class-Action Lawsuits Following TriZetto Data Breach

**Executive summary:** Cognizant's healthcare claims subsidiary TriZetto suffered a data breach in which attackers had access from November 2024 until discovery on October 2, 2025, exposing sensitive personal data (SSNs, financial account information, home addresses) for at least 100 individuals; class-action lawsuits accuse the firms of delayed notification and insufficient disclosure of root cause and remediation.
