This solution brief focuses on securing operational technology environments, where legacy systems and flat networks create visibility gaps and allow attackers to move undetected. It explains how Illumio integrates with NVIDIA BlueField DPUs to deliver hardware-accelerated segmentation directly at the edge. This approach offloads enforcement to hardware, enabling real-time visibility and control without impacting performance. It also allows organizations to modernize security without replacing existing infrastructure. The key takeaway is that combining software-defined segmentation with hardware acceleration enables fast, scalable Zero Trust enforcement in complex OT environments while maintaining performance and reliability.
