Illumio

Illumio is a cybersecurity company that employs microsegmentation, which is a way of granularly segmenting a network. This process involves dividing a network into smaller, distinct sub-networks that enable IT teams to deliver unique security controls and services to each sub-network. As a result, an attacker may breach a network but can’t move laterally across a company’s network in search of more valuable systems. Microsegmentation is a critical building block for enterprises planning to implement a comprehensive zero trust architecture. The key principle in this is defaulting to view every request across a network as untrustworthy. Granular network policies can also be used to ensure entities (users, machines) are only connecting to other entities that they absolutely need to. This hardens an enterprise’s network and makes it easier to enforce zero trust.
