Everlywell

Everlywell is a digital health company operating a Biomarker Intelligence Platform that turns complex diagnostic data into personalized health insights. The stack integrates AI-powered technology with virtual care and patient engagement systems. The company has delivered close to 1 billion personalized health insights across a U.S. footprint, partnering with hundreds of enterprise clients including 8 of the 10 largest U.S. health plans. The threat surface here is substantial and specific: protected health information (PHI) at scale, AI/ML pipelines processing sensitive biomarker data, and integrations with major health plan systems. The attack model spans data exfiltration, model poisoning, API-layer exploitation, and regulatory exposure under HIPAA. Security teams operating in this environment are dealing with healthcare-specific compliance frameworks, not just generic cloud posture management. Technical domains include AI/ML infrastructure, advanced diagnostics pipelines, and patient-facing engagement systems - all of which demand security engineering that understands both the data sensitivity and the clinical stakes. With 60 million people's health data flowing through the platform, the work is concrete: securing biomarker intelligence at the intersection of diagnostics and digital health.
