Case Study: US-Based Natural Gas Utility Operator achieves air-gap breach detection and hardware visibility with Sepio

US-Based Natural Gas Utility Operator Company - Customer Case Study

A large US-based natural gas utility operator discovered that highly sensitive operational documents had been stolen from its supposedly air-gapped critical network. The customer’s security team initially ruled out Internet leakage and removable media, but the investigation revealed that the environment had been breached through a peripheral-based attack involving a USB HID device that could emulate a mouse and keyboard.

Sepio addressed the issue with its HAC-1 hardware visibility and rogue device mitigation solution, which fingerprints connected peripherals, detects anomalous behavior such as a mouse acting like a keyboard, and helps block malicious devices. By providing complete visibility across hardware assets and enforcing policy-based controls, Sepio helped the utility identify and mitigate hidden hardware threats that bypassed traditional air-gap and USB protections.
