Case Study: Practice Fusion achieves proactive, real-time EMR performance and patient-data-safe monitoring with ExtraHop

Practice Fusion Delivers EMR Performance to Help Doctors Save Lives

Practice Fusion is a fast‑growing, free web‑based EMR used by more than 150,000 providers and housing 50 million patient records. As usage surged (270% year‑over‑year), the Technical Operations team needed better, correlated visibility across their three‑tier .NET application to ensure availability, performance, and patient privacy while supporting rapid code releases and infrastructure changes.

Practice Fusion deployed ExtraHop’s passive, wire‑data APM to monitor performance in staging and production, including real‑time SSL decryption without storing PHI. The platform delivered end‑to‑end visibility that enabled proactive problem resolution, faster, lower‑risk rollouts, a successful physical‑to‑virtual migration that avoided ~$75,000 in hardware costs, and stable support volumes even as user numbers doubled.
