Case Study: West Burton Energy achieves 98% fewer threat alerts and 87% greater efficiency with Tenable Networks OT Security

West Burton Energy Reduces Threat-Detection Alerts by 98% and Improves Efficiency by 87% Using Tenable OT Security

West Burton Energy, an advanced UK power and battery storage facility, needed a better way to secure its converged OT/IT environment after a spin-off left a small security team managing a large, complex plant. The team was burdened by manual, spreadsheet-driven asset tracking, excessive false-positive alerts, delayed OEM guidance, and difficulty proving compliance.

Tenable Networks implemented Tenable OT Security, with Tenable Nessus used in one OT environment for broader scanning and visibility. The solution gave West Burton Energy centralized asset inventory, early vulnerability detection, and better prioritization, cutting reported events by 98%, improving efficiency by 87%, and saving more than 200 hours per year previously spent on manual asset management.
