As organizations grow and their networks become more complex, the need for effective security controls becomes paramount. One of the most powerful strategies for securing a network and mitigating the risks posed by cyberattacks is network segmentation. By dividing a network into smaller, isolated segments, network segmentation reduces the impact of potential security breaches and limits attackers’ ability to move laterally across the network.

This article explores the concept of network segmentation, its role in cybersecurity, and how it can be implemented to strengthen your organization’s security posture.

What is Network Segmentation?

Network segmentation is the practice of dividing a large network into smaller, distinct subnetworks or segments, each operating as its own isolated environment. This approach ensures that traffic within a segment is contained and cannot freely move to other segments without passing through a controlled and monitored security checkpoint, such as a firewall or router with specific…
