Oura makes the Oura Ring, a smart ring worn on the finger that collects biometric data and surfaces health metrics to users. The device tracks sleep, activity, readiness, and over 50 additional wellness signals. More than 5.5 million rings are in the field worldwide, generating continuous streams of biometric data from millions of users - a scale that creates both opportunity and responsibility around data security, privacy, and system integrity.
The company operates across multiple continents with over 900 employees, including more than 30 in-house PhDs. Twelve-plus years of research and product development underpin the platform. This combination of scale, distributed user base, and research intensity means Oura's infrastructure must handle persistent connectivity from wearable devices, secure handling of sensitive health telemetry, user authentication and data access controls, and the defense of a centralized system that aggregates biometric information from millions of sources.
Security and privacy sit at the operational core: a wearable health company stores intimate data about sleep cycles, heart rate variability, body temperature, and activity patterns. Threat models include device-to-cloud communication integrity, protection of personal health information in transit and at rest, defense against unauthorized access to user accounts, and resilience of backend systems serving real-time health data. The security posture must be credible to users who are willing to wear the device only if they trust how their data is handled.
