What is a key benefit of using nanosegmentation in Illumio?

The key benefit of using nanosegmentation in Illumio is the isolation of sensitive workloads. Nanosegmentation involves dividing the network into very small, manageable segments, which enables organizations to enforce granular security policies. This increased level of segmentation means that sensitive workloads can be isolated from other parts of the network, thereby minimizing the attack surface and limiting the lateral movement of threats.

The isolation allows for specific security controls to be applied to sensitive data and applications, ensuring that they are only accessible to authorized users and services. This is particularly vital in environments where compliance with regulations such as GDPR, HIPAA, or PCI-DSS is required, as it helps to protect sensitive information from unauthorized access and potential data breaches.

While the other options address potential implications of better network management or cost efficiency, the primary distinction of nanosegmentation within the Illumio framework is its capacity to enhance security through the precise isolation of critical workloads. By focusing on workload isolation, organizations can fortify their defenses against internal and external threats effectively.
