Our main use case is the distributed firewall. NSX can segment every application and server based on the ports they need to communicate externally. Ports that aren't required are inactive, so we activate them for some specific applications. We can get the ports from the application guys, activate the ones we need, and then disable the rest of the ports. We've done other things with NSX, but it's just mostly about the distributed firewall.
Systems Engineer at a tech services company with 1-10 employees
A flexible option for managing security, but setup is complex and documentation is lacking
Pros and Cons
- "NSX's stand-out function is the distributed firewall. The firewall system is just top-notch, and I haven't seen another solution like it."
- "NSX could better integrate with open-source products. Of course, it integrates with some, but I know many people are uncomfortable deploying NSX with certain open-source solutions, such as Radar."
What is our primary use case?
How has it helped my organization?
We typically run a lot of vulnerability assessments — sometimes spam testing — and get a lot of bad results because some ports are open. I think NSX has significantly cut down on that. Right now, we have been able to fix almost all of our problems with unnecessary ports being opened and related issues. We are secure in this specific aspect, so we can log other options.
What is most valuable?
NSX's stand-out function is the distributed firewall. The firewall system is just top-notch, and I haven't seen another solution like it. Aside from that, there are numerous other cases where NSX comes in handy. For example, we've done intrusion prevention and implemented some next-generation firewalls for service training. We deployed some next-generation firewalls inside certain servers. Then we could bring all the traffic down that was meant to lead each server to a specific firewall. The security guys put policies on the firewall for checking signatures and hash values to contain particular security breaches within the server and prevent them from affecting the network. So we could use the particular firewall that we usually use and use it within the server close-up at the data center instead of the VH.
What needs improvement?
NSX could better integrate with open-source products. Of course, it integrates with some, but I know many people are uncomfortable deploying NSX with certain open-source solutions, such as Radar. They don't integrate so well, and the integration is usually so complex that many people would rather not use them.

June 2025

Learn what your peers think about VMware NSX. Get advice and tips from experienced pros sharing their opinions. Updated: June 2025.
860,632 professionals have used our research since 2012.
For how long have I used the solution?
I've been using VMware NSX personally for one year now, but I'm a consultant on this product, so I've deployed it for multiple customers.
What do I think about the stability of the solution?
We've experienced some bugs with NSX's user interface. For example, sometimes we click something, and it's not clicking. But they put out a lot of updates and patches. Also, they've added some particular boards on the applications. So with every update, they make the user interface more stable.
What do I think about the scalability of the solution?
You can scale NSX if you have the resources, but it's usually expensive and complex to scale up.
How are customer service and support?
VMware support is great. I would rate their support eight out of 10.
How was the initial setup?
The NSX setup is complex. That's one area where they could improve. Generally, it's too complicated to deploy. You can spend two or three days on it. And if you've never done it before, it might take a week. So it takes a relatively long time and lacks comprehensive end-to-end documentation. We had inadequate documentation when we implemented it, but I think it's better now. Total deployment for us took more than two weeks, but there were some breaks in that time where we stopped working on it. We weren't under any deadline. If we were pressed, we could have finished in four or five.
After the initial setup, NSX doesn't require a whole lot of maintenance. It's mostly troubleshooting, checking error codes, etc. There is no dedicated maintenance personnel specifically for NSX. Some guys in the IT department support this solution along with several other solutions. We have about four to five people handling that side of things, but there are six of us in the whole department responsible for infrastructure.
What was our ROI?
It's hard to judge with new deployments because you need some time to start seeing a return. But after someone has had one or two years to achieve a mature deployment on the product, they'll generally be happy that they spent the money. After a year, I'm beginning to see the return on investment, but everyone would argue that it's still expensive for the first two or three months.
What's my experience with pricing, setup cost, and licensing?
VMware NSX is expensive.
What other advice do I have?
I rate VMware NSX seven out of 10. If you are considering NSX, I suggest that you practice the deployment and know your use case. Know what you want to do with it and understand why you want to use the product. Identify the security features you want to use and consider what it's doing for your infrastructure. We're still exploring the features. I'm not sure we're using all the features that come with the application. There are so many that we have not used. For now, we're looking at more use cases and expanding on that knowledge.
Which deployment model are you using for this solution?
Hybrid Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

Stable, great for controlling virtual switches and makes it easy to establish VLANs
Pros and Cons
- "Overall, for me, it's a good solution and has been working well."
- "Occasionally the licensing is not very clear. They should make it easier to understand."
How has it helped my organization?
The full integration has been great. Its infrastructure and its ability to be part of the whole application are very useful for organizations.
What is most valuable?
The solution is great for controlling virtual switches and it is easy to establish VLANs and micro-segmentations. All those things are very useful.
The stability is pretty good.
Overall, for me, it's a good solution and has been working well.
What needs improvement?
I cannot recall coming across any missing features. At this time, there is nothing I would need in a future release.
Occasionally the licensing is not very clear. They should make it easier to understand.
For how long have I used the solution?
I have experience using the solution for around 25 years, on IT, however, for the last 10 years I've been working deeply on this and over the decade I have been more focused on software. In the last 4 or 5 years, I have had more and more focus.
What do I think about the stability of the solution?
The stability is good. Our customers don't seem to have any issues with bugs or glitches. It doesn't crash or freeze.
What do I think about the scalability of the solution?
I haven't really dealt with scaling the solution. I can't speak to how it is.
How are customer service and support?
I've never been in contact with technical support in the past. I can't speak to how helpful or responsive they are.
Which solution did I use previously and why did I switch?
I also have experience using Red Hat. However, sometimes I have had some problems with it. It can be a bit more difficult in terms of integration with other vendors.
How was the initial setup?
I didn't actually handle the implementation. I'm working more on the design side, not on setup or configuration. Therefore, I can't speak to how easy or difficult the implementation process is for users.
What's my experience with pricing, setup cost, and licensing?
The licensing is complex. Sometimes I have trouble understanding it.
What other advice do I have?
We are VMware integrators and partners.
I'd advise new or potential users to be aware that you will have to integrate it with other solutions. You'll need to look at how it fits in with all of your infrastructure, including IT infrastructure, for example.
I'd rate the solution at a nine out of ten. It's been very good overall.

Intuitive system, highly scalable, and reliable
Pros and Cons
- "I have found the system to be very intuitive, functional, and they have great technology."
- "In the future, the solution should be compliant with internet NIC."
What is our primary use case?
We use the solution mainly for micro-segmentation and to permit security on flat networks without a V-LAN.
What is most valuable?
I have found the system to be very intuitive, functional, and they have great technology.
What needs improvement?
One of the areas that we are struggling with is how do we perform the same security level as we had for an NSX solution for the legacy system. For example, if I have a switch, and I am connecting a legacy application on the legacy system that does not support the hyper vision or another feature, is possible to push the security topic to the switches to be compliant, or compliant with an NSX component, and to perform the same security level as we perform for hyper vision side. It would be beneficial for us if there was better integration with legacy systems.
In the future, the solution should be compliant with internet NIC. They could deploy this NIC into some switches, servers, or other product. It would be interesting to have this sort of NIC stamped by VMware, and we could push some security feature into it. It would be a very useful feature. I do understand VMware is virtual and not on a physical device path but this would be a good endeavour.
For how long have I used the solution?
I have been using the solution for approximately five years.
What do I think about the stability of the solution?
The solution is completely stable.
What do I think about the scalability of the solution?
The solution is highly scalable. One of the biggest infrastructures we have deployed the solution in has approximately 70,000 people using the solution.
How was the initial setup?
The installation has been complex.
What about the implementation team?
This solution can be very complex to deploy. We have assembled complex deployments at a few huge network site. We work for several customers in the communication and industrial sectors that have complex environments.
What's my experience with pricing, setup cost, and licensing?
The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced.
What other advice do I have?
I would definitely recommend this solution to others. I have deployed it in many different types of environments and it operates well.
I rate VMware NSX an eight out of ten.
