What is the main purpose of network segmentation?

The primary purpose of network segmentation is to enhance performance and security by dividing a larger network into smaller, more manageable segments. This approach allows for better traffic management, as it reduces congestion by limiting broadcast traffic to specific segments. It also improves security posture by isolating different parts of the network, meaning that a breach in one segment does not necessarily compromise the entire network. Each segment can be secured with tailored policies and controls, making it easier to implement and enforce security measures specific to the needs of that segment.

In addition to performance and security benefits, segmentation assists with better organization of network resources, making it easier to manage and allocate appropriately. This configuration facilitates the implementation of various security measures like firewalls and access controls tailored to the needs of different segments, further safeguarding sensitive information and critical resources.
