What is the primary purpose of network segmentation?

The primary purpose of network segmentation is to divide a network into smaller, manageable sections. This approach enhances the overall security, performance, and manageability of the network. By breaking a large network into smaller segments, it becomes easier to isolate and contain issues such as congestion, security breaches, and failure of network resources.

Additionally, segmentation can improve network performance by reducing the size of broadcast domains, which lowers the amount of unnecessary traffic that can slow down communication. Each segment can have its own security policies, which allows for tailored protections and access controls based on the specific needs and risks associated with different segments of the network. This strategic separation is a fundamental principle in both network design and cybersecurity, fostering greater operational efficiency and robust security posture.
