Case Study: Major Healthcare Company neutralizes insider threats and prevents sensitive data theft with OpenText ArcSight Intelligence

ArcSight Intelligence neutralizes insider threats and prevents sensitive data theft

A large U.S. healthcare organization with more than 12,000 internal users faced significant insider‑threat risk to sensitive patient data. Its SOC relied on hypothesis‑based threat hunting but struggled with a flood of distracting false positives and needed more accurate behavioral intelligence to spot anomalous activity.

The organization deployed CyberRes ArcSight Intelligence in a hosted cloud environment to apply contextualized behavioral analytics and unsupervised machine learning. ArcSight Intelligence identified and neutralized an administrator’s exploit attempt against an EMC application, detected subsequent re‑authentication attempts after termination, reduced false positives, improved threat‑hunting efficiency, and the team plans to expand data sources to broaden coverage.
