A Network Segmentation solution is a cybersecurity strategy and technology used to divide a computer network into smaller, isolated segments or zones, each with its own security controls and access policies. This segmentation helps limit the spread of cyber threats, contain breaches, and reduce the attack surface by ensuring that users and devices can only access the resources they are authorized to use. By logically or physically separating critical systems—such as finance, HR, OT, or IoT networks—from the broader corporate network, organizations can enforce granular security controls and respond more effectively to threats.
Network segmentation enhances business security by preventing lateral movement of attackers within the network, reducing exposure to ransomware and data exfiltration. It plays a vital role in regulatory compliance (such as PCI-DSS, HIPAA, and GDPR), where data access and isolation are key. From a business continuity standpoint, segmentation ensures that an attack in one part of the network does not disrupt operations enterprise-wide. Whether implemented through VLANs, firewalls, software-defined networks, or microsegmentation, this approach significantly boosts an organization’s resilience to internal and external threats.
