Traditional perimeter-based network security models are broken, but with a concept called micro-segmentation, you can develop ‘Zero Trust’ networks. According to Forrester Research they are 'the only answer' to today's security threats.
Zero Trust assumes threats are everywhere, even inside the data center. Micro-segmentation enables securing data center workloads. Internally. Previously, this had been hardware-intensive and costly. Now VMware NSX allows simplified, cost-effective micro-segmentation for true Zero Trust networks.
