CyberGuard IT-OT architecture implements a four-zone segmented defense model protecting enterprise IT, DMZ, SCADA supervision, and operational technology shop floor. Traffic flows through layered firewalls (NGFW IT, DMZ inspection, OT micro-segmentation) with unidirectional data historian, bastion jump servers, and decontamination kiosks enforcing strict IT-OT isolation. This architecture prevents lateral movement and direct IT-to-OT communication, addressing critical industrial control system vulnerabilities. Fork this diagram on Diagrams.so to customize firewall rules, add additional sensor networks, or adapt zone boundaries for your manufacturing environment. The SOC defense platform provides unified visibility across all four zones while maintaining air-gap principles.
