Products & Services
Illumio offers solutions through the Illumio Platform, which includes two primary products:
Illumio Segmentation
A Zero Trust-based segmentation solution that prevents the lateral movement of threats across hybrid and multi-cloud environments. It supports use cases in public clouds (formerly Illumio CloudSecure), data centers (formerly Illumio Core), and endpoints (formerly Illumio Endpoint). Illumio Segmentation enables organizations to visualize communication flows, enforce granular policies, and isolate high-value assets to contain breaches and ransomware attacks.
Illumio Insights
An AI-powered cloud detection and response (CDR) product that provides real-time visibility into risks, threats, and potential attack paths. It leverages an AI security graph to deliver actionable intelligence for proactive containment and rapid incident response.
Breach Containment
Illumio Segmentation limits the impact of breaches by isolating compromised workloads and preventing unauthorized lateral movement. Illumio Insights complements this by using AI-driven analytics to detect anomalies and vulnerabilities, integrating CDR capabilities for real-time threat monitoring and response. The platform’s AI Security Graph maps communication patterns and highlights potential attack paths, enabling preemptive containment and rapid remediation.
A Forrester Total Economic Impact study reported that organizations using Illumio experienced reduced breach-related costs and downtime.[5]

Illumio’s customers span sectors such as finance, technology, and hospitality.[6]
