Illumio provides microsegmentation through host-based enforcement using existing operating system firewalls, combined with visual maps of workload communications. This lets teams define policies and block lateral movement without redesigning networks.
The company markets breach containment as a core outcome and extends segmentation to cloud workloads, Kubernetes and endpoints.
Innovation Matrix Assessment
Has extended from data center segmentation to cloud, Kubernetes and detection of lateral movement.
Visibility maps plus enforcement make containment practical without network rearchitecture.
Large enterprise base; Forrester Wave Microsegmentation Q3 2026 Leader per vendor announcement.
Agent-based segmentation decoupled from network topology was a notable shift in how segmentation is done.
Containment of lateral movement is well-evidenced by customer use, but independent test data was not reviewed.
Assume-breach architecture and ransomware containment remain priorities.
Why CISOs Should Care
Limits blast radius of ransomware and intrusions by blocking lateral movement across workloads.
What Makes It Different
Enforces policy on the host itself via native firewalls, independent of network topology.
