ArcSight ESM Introduction
ArcSight ESM (Enterprise Security Manager) is a market-leading SIEM platform developed by Micro Focus (now OpenText). It aggregates and correlates security events from across OT and IT environments, enabling real-time threat detection, compliance reporting, and incident response. When deployed in critical OT environments, it provides centralized visibility into network traffic, system logs, and security events — helping SOC teams detect, investigate and respond to threats at operational scale.
By forwarding OT security event data through Cyberium’s OWA (One-Way Architecture) via a direct Syslog connector, ArcSight ESM receives a unidirectional, tamper-proof stream of security events — preserving operational integrity while enabling full-spectrum threat detection across OT and IT environments.
