Illumio

Illumio is a Zero Trust Segmentation platform designed to limit the impact of breaches by dynamically isolating workloads, applications, and devices across hybrid and multi-cloud environments. It focuses on preventing lateral movement inside networks rather than relying solely on perimeter defenses, helping organizations contain attacks before they spread. The platform provides real-time visibility into communication flows, enabling security teams to understand and control how systems interact at scale.

Key capabilities include granular microsegmentation based on workloads, labels, and policies rather than static network constructs like IP addresses or VLANs. Illumio allows security teams to visualize application dependencies, simulate policy changes, and enforce segmentation policies consistently across data centers, public clouds, and endpoints. Its enforcement is agent-based and supports major operating systems and environments, providing fine-grained control without requiring major network redesigns. Integration with SIEM, SOAR, and other security tools enables automated response and improved incident containment.
