Illumio is a cybersecurity company focused on breach containment across hybrid, multi-cloud environments. Its AI-powered platform helps organizations map traffic and dependencies, assess risk, define security controls, and contain threats before they spread. The company’s approach is centered on reducing lateral movement and limiting the business impact of ransomware and other attacks while advancing Zero Trust security.
Illumio organizes its portfolio around AI-powered detection and response and segmentation-based containment. Across cloud, data center, endpoint, server, and container environments, it gives security teams the visibility to understand communication paths, the policy controls to enforce least-privilege access, and the operational tools to isolate compromised systems quickly.
Offerings, Capabilities, and Integrations

The company extends these capabilities through integrations that connect Illumio with broader security and operations workflows. Its documented ecosystem includes SIEM and SOAR tools, IT service management, cloud-native and firewall environments, asset discovery platforms, and automation tooling, with integrations spanning Microsoft Sentinel, Splunk, ServiceNow, Wiz, Check Point, Fortinet, Palo Alto Networks, Armis, Claroty, Ansible, and Terraform.
