cabecera Segmentation


Segmentation is the OpenNAC Enterprise module that enables you to automatically segment corporate networks. The segmentation you can perform on a corporate network determines the network segment to which a device will be assigned after the evaluation of several parameters (user identity, role, connection time, user device, etc.)

Network segmentation can be carried out in different ways to maximize benefits for the infrastructure: grouping different network components for a more efficient authentication and authorization process.

The connection is assigned a segment or a group which has a given set of access rights and permissions.
