What is a major benefit of network segmentation?

A major benefit of network segmentation is optimized performance and enhanced security. By dividing a network into distinct segments, organizations can isolate sensitive systems and data, limiting access to only authorized users or devices. This reduces the risk of lateral movement by potential threats within the network.

From a performance perspective, segmentation can minimize congestion, as traffic is contained within smaller segments rather than being broadcast across the entire network. This targeted approach can lead to improved speeds and reduced latency, facilitating better overall performance for applications and services.

Additionally, enhanced security is achieved because, in a segmented environment, it becomes easier to monitor, control, and protect specific parts of the network. For example, if a breach occurs in one segment, the threat can be contained without affecting other network parts. Thus, segmentation plays a critical role in establishing strong security postures and efficient network performance.
