Hoag operates a regional healthcare delivery system across Orange County, California, running two acute-care hospitals, 18 urgent care facilities, 13 health and wellness centers, and seven specialized clinical institutes. The system treats approximately 350,000 outpatients and nearly 30,000 inpatients annually, with a medical staff of roughly 1,800 physicians. U.S. News & World Report ranks it as the highest-ranked hospital in Orange County and the only Orange County hospital in California's top 10.
The organization's clinical footprint spans oncology, digestive health, cardiology, neurosciences, spine care, women's health, and orthopedics. It holds Magnet designation from the American Nurses Credentialing Center and invests in clinical research and medical technology. Founded in 1952 as a nonprofit, faith-based institution, Hoag operates across multiple care delivery modes - from acute inpatient to urgent and preventive outpatient services.
Healthcare delivery systems of Hoag's scale and service breadth face substantial cybersecurity attack surface. Patient data flows across hospital information systems, electronic health records, urgent care point-of-service platforms, and affiliated specialty institutes. Ransomware targeting healthcare remains persistent threat; operational technology in clinical settings requires network segmentation and monitoring distinct from corporate IT. Third-party risk extends across vendor relationships in medical device management, lab systems, and health information exchange with other providers.
