2026 Agenda

With 15.14 billion IoT devices projected by 2029 and 77% of industrial firms still in initial OT security phases, operational technology networks have become the largest blind spot in enterprise security. This session addresses the critical challenge of securing interconnected OT/IoT environments where traditional security tools fail and unmanaged devices create pathways for devastating attacks.

The convergence of operational and information technology creates unprecedented vulnerabilities. Legacy OT systems, originally air-gapped, now connect to enterprise networks alongside proliferating IoT sensors, cameras, and smart devices. What's more, many are deployed without IT knowledge. These unmanaged endpoints become invisible attack vectors that bypass conventional security controls and enable lateral movement into high-value systems.

We'll explore how modern security architectures can overlay existing OT/IoT infrastructure without disrupting critical operations. Key topics include making devices unreachable while maintaining authorized access, securing protocols like DICOM/PACS in healthcare environments, and protecting industrial control systems without requiring costly replacement of functional equipment. The session demonstrates practical deployment strategies that work across manufacturing, utilities, healthcare, and smart city environments.

We'll pay special attention to wireless security gaps, where the majority of wireless networks lack basic manipulation protection, and supply chain vulnerabilities in embedded OT components. Real-world examples from government field operations and industrial deployments showcase immediate risk reduction while preserving operational continuity and avoiding capital expenditure on device replacement.

Takeaway

• Identify and inventory shadow OT/IoT devices creating security blind spots in your infrastructure
• Implement overlay security that protects legacy systems without operational disruption or replacement costs
• Secure wireless OT networks against manipulation attacks and unauthorized access
• Deploy deterministic access controls that prevent lateral movement from compromised IoT devices
