VMware Virtual Network Assessment is a free assessment that analyzes network traffic patterns within your data center. In 24 to 72 hours the assessment delivers:

  • Insights into the security risk (amount of East-West traffic) present in your network
  • A preview of actionable NSX micro-segmentation recommendations for your network
  • Opportunities to optimize network performance with NSX

Why should I care about East-West traffic?

Traditional approaches to securing a data center are focused on building a strong perimeter to keep threats outside the network. However, little is done to protect the network once a threat is inside the network. East-West (server-to-server) traffic accounts for more than 80% of overall data center traffic, but it’s largely unprotected, leaving you at risk. Virtual Network Assessment shows what percent of your data center traffic is “East-West” and not protected by your perimeter firewall.

How do I get started with micro-segmentation?

It can be a labor-intensive process to figure out what security policies to put in place, requiring time-consuming tasks such as identifying which servers are talking to each other and what ports are open. Virtual Network Assessment gives you a preview of how to micro-segment your network and recommends firewall rules to help you get started.
