Breaking the Myth: “Rail systems are air-gapped”

“Rail systems are air-gapped” — or are they?

This video challenges one of the most persistent cybersecurity myths in the railway industry: the assumption that train networks are disconnected and therefore secure.

In reality, modern railway systems increasingly rely on wireless technologies like GSM-R and remote access, making them vulnerable to cyberattacks — even if they’re technically “air-gapped”.

We explore how this outdated mindset can lead to dangerous complacency, why encrypted wireless communication is not enough, and how attackers can exploit remote interfaces, jam signals, and even trigger train stoppages without breaching physical perimeters.

Learn why assuming your railway OT network is breachable is the first step toward securing it. Get practical insights on how to detect vulnerabilities, enforce segmentation, monitor critical assets, and implement best-in-class railway cybersecurity strategies.

Whether you’re a CISO, rail operator, or OT network engineer — this video is a must-watch.
