Health Care Service Corporation (HCSC) is the largest customer-owned health insurer in the United States, serving more than 27 million people across five states (Illinois, Montana, New Mexico, Oklahoma, and Texas). With nearly a century of experience since its founding in 1936, HCSC operates as an independent licensee of the Blue Cross Blue Shield Association, providing comprehensive health coverage options for employers of all sizes, individuals and families, and Medicare and Medicaid plans. The company employs over 35,000 people who are dedicated to expanding access to quality, cost-effective healthcare. Beyond traditional health insurance, HCSC offers related healthcare products and services including pharmacy solutions, life and dental insurance, and health data technology. The company focuses on three core pillars: expanding access to care, improving affordability, and empowering member health through compassion and innovation. HCSC is committed to making a positive impact in communities through its mobile health programs, volunteer initiatives, and major grant programs that have impacted hundreds of thousands of people. As a mutual legal reserve company, HCSC is member-owned, meaning it operates in the best interest of its customers rather than shareholders.

Emory Healthcare operates 11 hospitals and a clinically integrated network serving 26,000 employees across Georgia - which means the attack surface is sprawling. The threat model here is healthcare-standard: HIPAA compliance, ransomware targeting clinical systems, and the operational risk of downtime in environments where EHR access, imaging systems, and connected medical devices directly impact patient outcomes. With 3,800 physicians and over 50 specialty areas generating protected health information at scale, data segmentation and access control aren't theoretical - they're daily operational requirements. The security function supports both clinical operations and the research side of an academic health system tied to Emory University. That dual mandate means protecting patient data while enabling collaboration across research networks, which introduces federation and data-sharing complexity. The infrastructure spans legacy hospital IT, modern cloud services for analytics, and operational technology in clinical settings - ventilators, infusion pumps, imaging equipment - all of which require different threat modeling than standard enterprise environments. Established in 1997 and expanded through the Emory Healthcare Network since 2011, the organization has been consolidating what were once independent hospitals into a unified system. That history suggests ongoing integration work: harmonizing security policies, centralizing identity management, and standardizing tooling across acquisitions. The scale and regulatory environment demand mature incident response, vulnerability management across heterogeneous systems, and the ability to operate under the assumption that you're a target.

In 1999, Lifepoint Health began with a simple but powerful vision: to bring quality healthcare closer to home in communities that needed it most. Founded with 23 locations across nine states, the company recognized a critical gap in non-urban healthcare access and set out to fill it. What started as a network of community hospitals has evolved into a diversified healthcare delivery network spanning the entire care continuum - from acute care hospitals to rehabilitation and behavioral health facilities serving patients coast to coast. Today, Lifepoint Health stands as a national healthcare leader with 60 community hospital campuses, more than 70 rehabilitation and behavioral health hospitals, and over 300 additional sites of service across 33 states. The company's mission of 'making communities healthier'® drives every decision, from the cutting-edge technologies implemented through Lifepoint Forward to the rigorous quality standards upheld by the National Quality Program. With a culture built on core values like Champion Patient Care, Do the Right Thing, and Make a Difference Together, Lifepoint has created places where patients choose to come for care, physicians want to practice, and employees are proud to work.
