Illumio

Illumio provides cybersecurity technology focused on Zero Trust Segmentation, microsegmentation and breach containment. Its platform maps communication relationships across cloud workloads, data centers, endpoints and other environments, then uses workload identity and policy to control allowed connections. By limiting unnecessary communication, organizations can reduce lateral movement and contain ransomware or other attacks after an initial compromise. Illumio's approach is based on assuming breach and enforcing least-privilege communication rather than relying solely on perimeter controls. Its value is controlling how systems communicate so a compromised asset cannot easily spread an attack to critical systems. Organizations evaluating Illumio should consider cloud environments, endpoint coverage, application dependencies, policy design and integration requirements. It is particularly relevant to enterprises seeking measurable segmentation and containment across hybrid and multi-cloud environments.
