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.

Key Cybersecurity Challenges to Overcome

Operational Imperatives Driving OT/IT Security Convergence
OT security devices generate continuous Syslog event streams from PLCs, SCADA systems and HMIs
Security analytics platforms depend on continuous, real-time access to OT security event streams
Delayed or filtered event forwarding reduces detection fidelity and response speed
The Cybersecurity Risks of Traditional Integration
Bidirectional Syslog connections expose OT systems to lateral movement from IT
Traditional bidirectional Syslog connections create persistent inbound attack surfaces into OT networks
SIEM collectors and log agents become high-value pivot points for attackers
Why Cyberium's OWA is the Ideal Architecture for Securing ArcSight ESM SIEM Connections?
