What Data Was Compromised

  • Full legal name, date of birth, and Social Security Number
  • Health insurance member ID and plan details
  • Diagnosis codes and treatment history
  • Provider names and treatment facility information
  • Claims amounts and billing codes
  • Prescription and medication data in some records
Why This Is Worse Than a Standard PII Breach: Medical record data cannot be changed. Your diagnosis history, claims, and prescriptions follow you permanently. Once exposed, they enable insurance fraud and medical identity theft for years.

A Systemic Architecture Problem

TriZetto functions as a hub — processing claims across multiple insurers and providers. A single intrusion unlocks data belonging to millions of patients who never interacted with TriZetto directly.

🔒
Zero-Trust Architecture
Treat every internal request as untrusted. Lateral movement enables the largest breaches.
🧱
Data Segmentation
Records belonging to different payers should be logically isolated.
📡
Continuous Monitoring
Bulk data access patterns must trigger automated alerts and session termination.
🗂️
Data Minimization
Retaining only necessary data reduces breach scale. Archival and purge policies are a security control.

Our custom software development team applies security controls that exceed HIPAA minimums because compliance is a floor, not a ceiling.
