Illumio CoreTM delivers real-time application dependency mapping and micro-segmentation by programming the native Layer 3/Layer 4 firewall of each host. Illumio uses an allow-list model, which means that all traffic is blocked by default. This approach prevents lateral movement of cyberattacks, obstructs ransomware, and enables Zero Trust across on-premises data centers, public clouds, private clouds, and containers.
