- TriZetto Provider Solutions breach exposed sensitive data of over 700,000 individuals
- Stolen information includes names, SSNs, insurer details, and member numbers
- Breach led to class-action lawsuits against Cognizant, TPS’s parent company
The number of people affected by the TriZetto Provider Solutions (TPS) data breach is now thought to have exceeded 700,000 people - far more than initially thought.
Deschutes County Health Services (DCHS), one of TPS’ customers, confirmed the news in a recent data breach notification published on its website.
In the data breach notification letter, it was said that TPS spotted unauthorized activity in October 2025 and launched an investigation, which determined that threat actors broke in almost a year prior - in November 2024. Since then, they have been exfiltrating sensitive personal and health data on more than 700,000 people.
Extorting the victims
The data belongs to TPS’ customers, it was said, and some of the affected organizations are Deschutes County Health Services, Best Care, and the La Pine Community Health Center. None of these companies were breached themselves - the breach occurred solely in TPS’ infrastructure.
The exposed data varies from person to person, but generally includes people’s names, addresses, birth dates, Social Security numbers (SSN), health insurer names, health insurance member numbers, and provider names.
DCHS stressed no medical diagnosis or treatment information, as well as payment data, was taken in the attack.
TriZetto Provider Solutions is a healthcare technology company and a subsidiary of Cognizant that provides healthcare organizations with software and services for revenue cycle management and claims processing.
