Case Study: Major Water and Wastewater Treatment Facility Supply Company achieves continuous SCADA protection and uninterrupted operations with Virsec

Major Water and Wastewater Treatment Facility Secures SCADA Systems

Major Water and Wastewater Treatment Facility Supply Company, a large U.S. water utility serving nearly one million people and processing roughly 100 million gallons daily, relied on AVEVA System Platform for SCADA, RTU and PLC control but faced persistent runtime vulnerabilities, limited security staff, and attacks that bypassed traditional defenses by operating in memory and fileless vectors. After evaluating options, the customer selected Virsec’s Security Platform for application control and control-flow integrity (CFI) to deliver application-aware workload protection across their distributed OT environment.

Virsec implemented its application-aware runtime protection—including memory CFI, file-system monitoring, and automated application control—hardening AVEVA Historian, SCADA and HMI components and protecting legacy applications without signatures or tuning. The Virsec solution delivered full-stack runtime protection with zero dwell-time: deviations are detected within milliseconds, stakeholders receive instant alerts and can respond immediately, fileless and memory-based attacks are stopped at the first step of the kill chain, and management overhead and resource consumption were reduced, ensuring continuous operations across the utility’s facilities.
