Protecting legacy OT systems against modern cyberthreats

The article highlights a growing and increasingly serious cybersecurity threat to manufacturing operations, particularly due to the convergence of IT and OT systems. Despite a long history of neglecting OT security, ransomware gangs and nation-state actors are now actively targeting these systems, exploiting vulnerabilities and causing significant operational disruption. The cost of addressing this threat is rising, driven by stricter supplier contracts, cyber insurance premiums, and increasingly stringent regulatory requirements. Addressing this requires a shift in mindset, focusing on long-term support and visibility beyond vendor lifecycles.
