Case Studies

U.S. Utility Company – Colorado


Cyber Security Testing Pro deployed GFI LanGuard to manage patching and vulnerability scanning across the client’s field service laptops, smart meter management consoles, and admin workstations. In 60 days, over 1,200 vulnerabilities were remediated, and system uptime improved by 25%.

U.S. Smart Infrastructure Agency – Ohio

A statewide initiative for smart transit and water management used Cyber Security Testing Pro and GFI LanGuard to audit their IoT-connected infrastructure. Rogue device alerts led to faster response times and eliminated unapproved network access in less than two weeks.

Canadian Gas Distribution Network – Saskatchewan

Cyber Security Testing Pro integrated GFI LanGuard into a hybrid IT-OT setup. Remote patch management and CVE tracking enabled automated compliance with NERC CIP policies, reducing manual effort by over 60%.
