Case Study: Major Oil & Gas Manufacturer achieves unified OT visibility and eliminates false alerts with Armis

How an Oil Refinery Eliminated Alert Fatigue and Created Contextualized OT Risk Insights

Major Oil & Gas Manufacturer, an energy petrochemical refinery with geographically dispersed refining, logistics, asphalt, renewable fuels, and retail operations, was struggling with OT security alert fatigue, false positives from its IDS, and limited visibility across unmanned and scattered environments. With too many ghost asset alerts and no unified view of OT, IT, and IoT risk, the team had difficulty distinguishing real threats from noise. Armis helped address these challenges with Armis Centrix™ for OT/IoT Security.

Armis deployed Armis Centrix™ for OT/IoT Security on-prem to correlate data from existing tools, enrich asset intelligence with operational context, and suppress low-value alerts while surfacing high-priority risks. The result was a unified risk view across converged OT-IT-IIoT environments, automated OT compliance and auditing, and faster detection and response. Armis identified and eliminated more than 12,000 false alerts, including ghost assets, external cloud assets, and after-hours activity, improving the customer’s operational efficiency and security posture.
