Case Study: Leading North American Energy Company achieves real-time device visibility, classification and control with ForeScout

Leading North American Energy Company - Customer Case Study

This leading North American energy producer operates across 25+ sites with roughly 3,500 employees and more than 20,000 endpoints, including field IoT devices. Their challenge was securing widely dispersed and rapidly deployed networks—isolating vendor and guest systems, keeping rogue or dual‑homed devices off the corporate network, maintaining accurate asset inventories for patching and compliance, and adding IoT/BYOD without introducing new vulnerabilities.

They deployed the ForeScout CounterACT platform and Enterprise Manager for agentless, real‑time device visibility, classification, policy‑based access control and integration with existing security tools. The solution automated discovery and inventory, enabled fast network segmentation in remote builds, and closed critical gaps—detecting 400 vulnerable hosts and remediating WannaCry exposure within 48 hours—while cutting field deployment time by weeks and providing ongoing asset reporting for patch management.
