Case Study: Large Healthcare Organization prevents security breach of sensitive patient data with OpenText ArcSight Intelligence

ArcSight Intelligence prevents security breach in sensitive patient data

A large U.S. healthcare organization that stores sensitive patient data and must comply with strict regulations like HIPAA faced the need to detect and stop advanced external attacks and insider threats while boosting SOC productivity by focusing analysts on the highest‑risk incidents.

The organization deployed OpenText ArcSight Intelligence — a cloud‑aligned solution using unsupervised machine‑learning to establish “unique normal” behavior baselines. The tool identified a previously dormant guest account that had hundreds of failed logins outside working hours and attempted to access a classified server; the team neutralized the activity before any breach, improving threat‑hunter efficiency and continuing to rely on ArcSight Intelligence.
