What does network segmentation primarily improve?

Network segmentation primarily improves performance and security by dividing a larger network into smaller, manageable segments. This division enhances overall network efficiency as it reduces congestion and allows for better allocation of resources. Each segment can be tailored to specific types of traffic or user groups, which can lead to improved performance in terms of speed and responsiveness.

From a security perspective, segmentation helps to contain potential threats. If an attack occurs within one segment, it is less likely to affect other segments, thus limiting the scope of potential damage. Additionally, with segmentation, security policies can be applied more effectively, allowing for different security measures to be implemented based on the sensitivity of the data or the type of users accessing each segment.

Overall, the combination of performance enhancement and increased security makes network segmentation a vital practice in managing modern networks.
