This case study describes how Tarrant Regional Water District (TRWD), serving 2.1 million people in North Texas, strengthened cybersecurity by adopting ExtraHop RevealX for network detection and response. With limited internal security resources, TRWD needed better visibility, baseline monitoring, and regulatory compliance support. RevealX enabled continuous packet monitoring, dependency mapping for custom water-service applications, and rapid troubleshooting, as shown on page 2. The platform helped uncover vulnerabilities, simplify audits under EPA mandates, and support investigations such as retrospective DNS searches after the SUNBURST incident. ExtraHop’s ease of deployment, unified dashboards, and detailed forensic context improved resilience across critical infrastructure operations.
