Yale New Haven Health

Yale Medicine, also known as Yale New Haven Health, is a healthcare organization headquartered in the United States. It provides a range of medical services to patients, including inpatient and outpatient care. The organization maintains electronic medical record systems and offers a patient portal for accessing health information. It also manages legacy medical records systems that originated from prior private practices before integration into its secure environment. These services support clinical operations and patient engagement across its facilities.

Yale New Haven Health operates a dedicated Digital and Technology Solutions team responsible for overseeing its information technology infrastructure. This team monitors network and application connectivity, and leads incident response when disruptions occur. In March 2025, the team identified an IT services issue, engaged Mandiant for investigation, and confirmed a cybersecurity incident while keeping patient portal and electronic medical records operational. In August 2022, the organization disclosed a breach involving unauthorized access to a legacy medical records system, noting that post‑acquisition electronic health records remained unaffected. These events illustrate the organization’s focus on cybersecurity preparedness and its collaboration with external experts to protect health information. No further details about the organization’s size, ownership structure, or broader market footprint are provided in the available source material.
