NSX introduced major customer advantages that were new in the marketplace. While the efforts on perimetral defense are well justified and effective in most cases, there are flaws.
For example, if a hacker penetrates the system, they only need to do it once. After the hacker gains system access, they often stay for a long time. Only NSX micro-segmentation offers the technology to contain and control attacks. NSX provides excellent visibility to target east-west movements inside data centers to eliminate this threat.
NSX also enables automated network configuration operations that accelerate application provisioning and overall service delivery. This improvement in provisioning time, from months or weeks to minutes, directly translates to increasing customer network deployment agility.
Placing the network engine close to the application positions NSX as the networking and security architecture for the cloud. Extending business workloads to a public cloud provider is possible with NSX, while maintaining the same level of control and security of a data center.
