Over 3.4 million patients had their personal and health insurance information compromised in a cyberattack on TriZetto Provider Solutions, a healthcare IT firm owned by Cognizant Technology Solutions. The company discovered suspicious activity in its web portal on October 2, 2025.

While no financial data was stolen, hackers accessed names, addresses, Social Security numbers, dates of birth, health insurance member numbers, and other medical information. TPS provides billing and claims management software to hospitals, physician practices, and insurers.

The company has implemented additional security measures and is offering credit monitoring to affected patients. Parent company Cognizant has faced previous major breaches, including a 2020 ransomware attack costing $50-70 million.
