Global IT services provider Cognizant is facing significant legal challenges following a data breach at its healthcare subsidiary, TriZetto Provider Solutions (TPS). Multiple class-action lawsuits have been filed, accusing the company of negligence in protecting vast amounts of sensitive patient data, including Protected Health Information (PHI). The suits allege not only a failure to implement adequate security controls but also a significant delay in notifying victims, exacerbating the potential harm. This incident highlights the immense responsibility and legal liability carried by third-party service providers in the healthcare sector and underscores the severe consequences of failing to meet data protection obligations under regulations like HIPAA.
TriZetto Provider Solutions (TPS) acts as a technology and services provider for healthcare organizations, processing claims and managing patient data. This central role makes it a high-value target for threat actors. While the exact technical details and timeline of the breach have not been fully disclosed by Cognizant, the lawsuits contend that hackers successfully accessed and potentially exfiltrated sensitive data. A key point in the legal filings is the allegation of a prolonged notification delay. Under many data breach notification laws, including HIPAA's Breach Notification Rule, companies are required to notify affected individuals without unreasonable delay. The lawsuits argue that Cognizant's failure to do so left millions of patients unaware that their data was compromised, preventing them from taking protective actions like freezing their credit or monitoring their accounts.
The lawsuits likely claim violations of various state and federal laws, including:
This incident provides critical lessons for organizations, especially those acting as third-party data processors.
New details emerge on TriZetto breach timeline, including nearly year-long discovery delay and recent notifications to Oregon residents.
New information reveals the TriZetto data breach, which began in November 2024, was not discovered until approximately October 2025, nearly a year after the initial intrusion. This significant delay has prolonged the risk of identity theft and fraud for affected individuals. The consequences continue to expand, with thousands of residents in Oregon now receiving notification letters regarding their exposed Protected Health Information (PHI). This update underscores the long-term impact and challenges of supply chain breaches in healthcare.
