Why OT Security Is the Next Frontier for CISOs

Episode 22 of Cybersecurity Business with Fexingo explores why operational technology (OT) security has become the most urgent priority for enterprise CISOs. Lucas and Luna examine the Colonial Pipeline ransomware attack as a turning point, then drill into a specific case: a 2025 water-treatment facility breach in Florida where attackers manipulated chemical controls via the same network as the HVAC system. They discuss the scale of the challenge — an estimated 3.5 million exposed OT devices globally, according to a 2025 Dragos report — and why traditional IT security tools fail in environments running legacy PLCs and SCADA systems. Luna asks whether convergence with IT security is realistic or a pipe dream. Lucas breaks down the shift from air-gapped to connected OT, the rise of OT-specific detection and response tools from companies like Dragos and Nozomi Networks, and why the SEC's new incident disclosure rules are forcing board-level attention. The episode closes with a look at how OT security is reshaping M&A strategy for industrial firms. #OTSecurity #OperationalTechnology #IndustrialCybersecurity #SCADA #PLCs #CriticalInfrastructure #VendorRisk #Convergence #Dragos #NozomiNetworks #SECRules #CyberInsurance #IndustrialIoT #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #CyberPodcast #NetworkSecurity Keep every episode free: buymeacoffee.com/fexingo
