Illumio is a zero trust segmentation platform that maps application dependencies and enforces workload-level policy to contain breaches across cloud, data center, and endpoints.
Illumio is a cybersecurity company headquartered in Sunnyvale, California that pioneered the zero trust segmentation category — providing visibility into application communication flows and enforcing workload-level micro-segmentation policies across hybrid cloud, data center, and endpoint environments to limit the lateral movement that makes ransomware and supply chain attacks so damaging. Founded in 2013, Illumio raised $225 million in a 2021 Series F that valued the company at $2.75 billion, reflecting enterprise demand for segmentation technology as a breach containment control independent of network perimeter tools. The company's core thesis is that breaches are inevitable and that security programs must invest in preventing attackers who have entered the environment from moving freely to reach high-value targets.
