Illumio

Zero trust segmentation platform restricting lateral movement between workloads, endpoints, and cloud resources.

Illumio maps traffic flows between workloads and enforces segmentation policy so a compromise of one system cannot spread freely. It operates across data centers, cloud, and endpoints without depending on network hardware. Founded in 2013, it is used by enterprises putting zero trust principles into practice at the network layer.
