- Company that offers post-discovery identity monitoring services.
The TriZetto data breach may have been going on for almost a year and affected around 3.4 million people, he admitted.
The company filed a new data breach notification with the Maine Attorney General’s Office and began notifying affected individuals about the incident, noting that it detected “suspicious activity within a web portal that some of TPS’ healthcare provider customers use to access our system” on October 2, 2025.
Follow-up investigation determined that an anonymous threat actor gained access to the system in November 2024 and, through October 2025, stole patient data.

The data includes names, dates of birth, Social Security numbers (SSN), health insurance membership numbers, provider names, health insurance names, primary insured information, and other demographic, health, and health insurance information. TriZetto emphasized that payment card, bank account and other financial information were not affected by this incident.
“At this time, we are not aware of any identity theft or fraud related to the use of any affected individual’s information,” he added, although data like this may appear on the dark web even years later.
In Maine AG’s filing, the company said exactly 3,433,965 people were affected. To help them, TriZetto offers free identity theft monitoring services through Kroll.
TechCrunch says several organizations have already confirmed that their patient information was compromised in this breach, including OCHIN, a nonprofit that provides healthcare technology to rural and community care providers.
Given the sensitivity of the data they create and maintain, healthcare organizations are among the most popular targets for cybercriminals.
TriZetto (TPS) is a healthcare technology company that creates similar software and tools for health insurers, hospitals, and other healthcare organizations. The tools are designed mainly for the management of administrative and financial processes.
