Nucor, the largest steel producer in North America, halted production across multiple sites after detecting unauthorized third-party access to IT systems. OT was not directly compromised, but the lack of true IT/OT separation forced a costly shutdown to contain the threat.

This incident shows a dangerous reality for industrial environments: when IT and OT are tightly coupled, even a contained cyber incident can trigger widespread operational disruption.

BlastWave’s network cloaking and microsegmentation would have helped prevent this outcome by making OT systems invisible to unauthorized users and blocking lateral movement before it could threaten production.
