How does Illumio achieve micro-segmentation?

Illumio achieves micro-segmentation primarily through the creation of policies that restrict communications between workloads based on defined security criteria. This approach allows organizations to apply granular security controls directly to individual workloads rather than relying solely on traditional perimeter security measures.

By defining specific policies, administrators can dictate which workloads can communicate with each other, and under what circumstances. This means that even within the same data center or cloud environment, communications can be finely tuned for security, significantly reducing the attack surface and limiting the potential spread of threats. Micro-segmentation thus enhances the overall security posture of the organization by isolating sensitive workloads and enforcing strict access controls that are easily managed and adapted to the changing threat landscape.

In contrast, the other options like implementing physical barriers, increasing network bandwidth, or using exclusive cloud service providers do not contribute effectively to micro-segmentation. Physical barriers do not address the challenges inherent at the workload level, and increasing bandwidth or focusing solely on cloud services does not inherently create the necessary segmentation between workloads that is the essence of Illumio's micro-segmentation strategy.
