Case Study: United Airlines improves OT visibility and reduces cyber risk with Armis Centrix™

United Airlines Uses Armis Centrix™ to Decrease OT Cybersecurity Risk

United Airlines, one of the world’s largest airlines, needed a better way to understand and secure its sprawling operational technology (OT) environment across airports and hubs. With thousands of OT devices and increasing cybersecurity and compliance pressure in the aviation industry, the airline lacked a complete, accurate inventory of its assets and the visibility needed to reduce risk. United Airlines turned to Armis Centrix™ from Armis to address these challenges.

Armis Centrix™ gave United Airlines agentless visibility into its OT estate, helping the team discover, categorize, and monitor devices such as switches, cameras, controllers, and other industrial systems. With integrations into existing security tools, Armis improved asset intelligence, helped prioritize vulnerabilities, and better prepared the airline for future regulatory requirements. United Airlines also used Armis to reduce noise in its inventory, cutting an initial view of over 3 million devices back to the assets that mattered most, while significantly improving OT security posture.
