Case Study: Major Oil & Gas Company achieves complete visibility and zero-trust endpoint control with Fortinet Network Access Control

Major Oil & Gas Company Secures Critical Infrastructure with FortiNAC Network Access Control

A major North American oil and gas company managing 5,000 endpoints across 200 locations needed to ensure no unknown or non-compliant devices could access its production network. Their environment included widely distributed industrial control systems and legacy remote switches that couldn’t support 802.1x, and many sites had limited bandwidth—so they required a way to validate and instantly quarantine devices without heavy hardware installs or traffic‑intensive setups.

They deployed Fortinet’s centralized, vendor‑agnostic Network Access Control, which supports legacy Cisco and HP equipment without 802.1x or local appliances, avoiding bandwidth issues and enabling fast rollout. Within a year they achieved full visibility and automated quarantine of rogue devices, integrated live inventory with SIEM/IDS/CMDB, implemented zero‑trust controls, saved hundreds of thousands of dollars versus competitors, and plan to expand coverage to their SCADA network.
