The Unseen OT Battlefield 

Protecting critical infrastructure from escalating OT cyberattacks

OT and ICS environments are no longer “behind the fence.” As IT/OT convergence accelerates, ransomware groups and nation-state actors are targeting the physical control layer for maximum operational impact, and operational technology is now a primary target. Bad actors are shifting from “data theft” to “maximum impact” attacks that disrupt physical operations.

This white paper delves into what’s driving the surge in OT intrusions, how real-world campaigns unfold from initial access through lateral movement and disruption, and why traditional, perimeter-based defenses keep failing in environments where downtime and patching constraints are non-negotiable.

It also outlines how Dispersive® Stealth Networking can support a more resilient OT security posture by reducing exposed attack surface, limiting lateral movement through granular segmentation, and enabling secure remote access across hybrid and legacy environments.
