Oil Refinery OT Security Improvement Case Study

This case study details the challenges and solutions faced by an oil refinery in enhancing its operational technology (OT) security. The refinery experienced alert fatigue due to a high volume of false-positive notifications from its Intrusion Detection System (IDS), which hindered the security team's ability to identify genuine threats. The company sought to reduce alert noise and gain unified visibility across its assets. The deployment of Armis Centrix™ for OT/IoT Security addressed these issues by optimizing data sources, providing asset intelligence, and enabling risk-based prioritization. The solution resulted in the identification of over 12,000 false alerts, improved operational efficiency, and automated compliance reporting. The case study highlights the transformation in the refinery's security posture, emphasizing the importance of comprehensive visibility and effective risk management in maintaining a secure operational environment.
