Network Segmentation

Software-based micro segmentation provides several key advantages over traditional infrastructure-based segmentation methods (like firewalls, VLANs, and ACLs):

Granular Control: It allows segmentation at the workload, application, or even process level, rather than broad network segments defined by physical devices. This fine-grained approach limits lateral movement if a breach occurs.

Dynamic Adaptability: Software-driven segmentation can automatically adjust to changes in the network environment—such as the creation, movement, or scaling of virtual machines and containers—without the need for manual reconfiguration of hardware-based rules.

Centralized Policy Management: Policies can be defined, enforced, and audited from a central platform across heterogeneous environments (data centers, cloud, and hybrid infrastructures), ensuring consistency and reducing configuration errors.

Operational Agility and Automation: Automated deployment and policy enforcement reduce manual tasks and human errors, accelerating response times to changes in the network or emerging threats.

Cost Efficiency: By leveraging software, organizations can avoid additional hardware investments and reduce ongoing operational costs while achieving robust security controls.

Overall, software-based micro segmentation provides a more flexible, scalable, and efficient approach to network security, particularly suited for modern dynamic and virtualized environments.
