Email remains one of the most underestimated cyber risks in operational technology environments . It is often treated as an IT-layer concern, something isolated from industrial processes and unrelated to the functioning of physical equipment. In reality, OT network security teams depend on a continuous flow of operational messages, automated alerts, vendor communications, firmware packages, and field reports that enter the environment through enterprise communication channel

Critical infrastructure operators now rely more than ever on accurate operational technology data. Logs, historian outputs, configuration reports, maintenance files, and compliance evidence all need to be transferred from OT systems to IT environments where analytics, monitoring, and decision-making take place.   While essential for operational continuity and regulatory compliance, this flow of information also introduces one of the most underestimated risks inside industrial

Energy and utility operators collaborate constantly with external vendors, contractors, and remote field teams. These partnerships often involve transferring files into protected OT networks , including software updates, diagnostic logs, engineering reports, and configuration changes.   But while the files themselves may seem harmless, the way they enter the network is where the risk lies. USB drives passed between field teams, portable laptops brought in by vendors, or remo

In industrial environments, the boundary between SCADA systems and corporate IT networks is often assumed to be secure. Yet in many architectures, these two domains are more connected than most realize. Whether through shared infrastructure, reporting interfaces, or vendor access, attackers increasingly exploit these connections to move laterally between operational and enterprise zones .   When a threat actor gains a foothold in one environment, the next objective is almost

For decades, operators in the energy sector have leaned on the belief that their OT environments are “ air-gapped ”, which means they are...
