Illumio

What the company sells

Illumio is a security company that sells the Illumio Breach Containment Platform, which includes Illumio Insights and Illumio Segmentation for hybrid and multi-cloud environments.

Illumio says it addresses lateral movement, the workload-to-workload movement inside an environment. Illumio says cloud-native controls were not built to cover this east-west traffic, and that each cloud provider has its own console, so there is no single policy view across Azure, AWS, GCP and OCI.

Illumio Insights is described on the Illumio site as a tool to identify lateral movement, detect attacks, and stop breaches at cloud scale. Illumio says it is powered by an AI teammate called Insights Agent, which supports prioritisation of threats with context-rich analysis, deep observability, and one-click containment.

Illumio Segmentation is described as a way to secure critical assets, workloads, and devices across a hybrid, multi-cloud environment. Illumio says it lets customers see risk, set policy, and prevent lateral movement.

For cloud security, Illumio says its platform works across the data center, endpoints, containers, Azure, AWS, GCP, and OCI, with or without an agent. Illumio says policy is label-based and follows the workload through auto-scaling, redeployment, and IP changes. Illumio says Draft-view shows which connections a rule would change before it goes live.

Illumio publishes pages for several industries. For financial services, Illumio says it helps secure systems from core banking to mobile apps. For energy and utilities, Illumio says it helps operators identify risks, detect threats, and contain breaches across IT and OT systems. For healthcare, Illumio says it blocks the spread of attacks across IT, OT, and medical devices. Illumio also has pages for government, manufacturing, telecom, and small and midsize businesses.

For compliance, Illumio names GDPR, HIPAA, PCI DSS, and DORA, and says it can generate audit-ready evidence of segmentation, policy enforcement, and breach containment efforts. Illumio says Microsoft deploys Illumio across its entire corporate IT environment.^{[1][3][7][8][9][10][11][12][13][14][15][16]}
