Overall Satisfaction with VMware NSX

VMware NSX is used by our data center for east-west firewall (Internal connections of the virtual environment, for all departments of the company), therefore, letting the physical firewall work only with north-south connections (Leaving the environment to the internet).
  • Internal routing of VXLans (virtual network isolated from the physical network) without the use of switches, as an attractive virtual machine on the same host.
  • Rules management is very easy, being able to use tags.
  • Tools that assist in troubleshooting, such as flow monitoring, packet capture and traceflow in a graphical interface.
  • The migration is still very complex, because the data collector generates a lot of data that is not transferred and if it is determined automatically through the data collector, the environment can be unsafe. A strict review of the rules is necessary before making production.
  • There will be a graphical interface to solve problems in case of need to connect to DLR and EDGE.
  • A little more quality in the support of VMware itself that currently does not solve the problems so quickly.
  • Distributed Firewall
  • VPN
  • Groups and Tags
  • DHCP
  • We are a company with 300 VM's and few departments, the investment was more for security, putting in ROI, we can mention that environmental security is priceless.
  • We have a simplified understanding of east-west rules, bringing a lot of satisfaction to the user, since creating and modifying rules is a very simple activity.
  • With NSX for virtual environment, the IT team was also very satisfied with the communication without the need for a physical medium (Switch for example). The machines that need more performance, are placed on the same physical Host, as a rule of affinity and with that the performance reaches the expected very easy.
I did some tests with Guardicore, however, we found the management interface and also the implementation way complicated, so we opted for NSX.

Recommendation 10 for large companies, with a data center with more than 1000 VM's on average is very appropriate, as the security of the environment can be divided between physical firewall and virtual firewall and have another separate management for cases of troubleshooting, having only physical firewall in these In some cases, the rules are immense and this can cause future problems.
For Medium / Small companies, I do not recommend it, as the main one is a physical firewall, (Remembering that NSX does not replace a physical firewall), as smaller companies with less rules, only a physical firewall can be used.
