The primary benefit of network segmentation is improved performance and security. By dividing a larger network into smaller, more manageable segments, it allows for better traffic management and reduces congestion. Each segment can be optimized for specific purposes, which can lead to better overall network efficiency.

From a security perspective, segmentation limits the potential impact of a security breach. If one segment of the network is compromised, the attacker is confined to that segment, preventing them from accessing the entire network. This containment strategy is essential for both protecting sensitive data and enhancing incident response efforts.

While increased bandwidth, reduced costs, and streamlined hardware requirements are valuable in certain contexts, they are secondary benefits that may arise as a result of improved performance and security achieved through effective network segmentation.
