This product brief explains how modern hybrid networks enable attackers to move laterally after initial access, making breaches more destructive and harder to detect. It highlights the limitations of perimeter-based security and the need for Zero Trust segmentation to contain threats. Illumio provides real-time visibility into workload communication, allowing organizations to identify vulnerabilities and enforce least-privilege access across cloud, endpoints, and data centers. It simplifies segmentation with scalable, unified policies and isolates compromised systems without disruption. The key takeaway is that segmentation is essential for stopping lateral movement, reducing risk, and building cyber resilience in modern distributed environments.
