Upsides:

The main reason we use the NSX product on our environments is to make life easier with virtual networking in a SDDC. The ease of use helps our thousands of customers to create their own SDDC with all of their enterprise applications. Virtual networking creates an unprecedented number of use-cases that can be used. Firewalling, VPN's, micro-segmentation, NIC-firewalling, gateway firewalling, BGP and lots more.

There is a rich third party integration possibility within the NSX product like Fortigate-VM! Last but not least, the implementation for NSX is relatively easy. You only need to install 3 appliances and you are good to go.

This is the reason it is used all the time in all our production environments. Review collected by and hosted on G2.com.

Downsides:

How easily NSX provides functionality to end-customers and/or cloud providers is something different from the configuration that needs to be done to use the product after installation. Next to this, I think the legion of different products such as AVI loadbalancing, IDS/IPS etc. could have a better integration into the main product. Most of these require additional appliances and or software to be used.

Furthermore, the API is vast and complete. However, the GUI seems to be behind in that part since not all API equivalent calls can be done with the GUI, which means that users that do not fully understand API calls the learning curve might be a bit harder in comparison with others that do understand these.

NSX is very powerful in microsegmentation or firewalling between VMs. There is no other product available that is able to perform the same level of firewalling within the vSphere environment or SDDC. Once setup, the NSX network virtualization allows easy, fully automated deployment of new virtual networks within the environment. Review collected by and hosted on G2.com.

NSX lacks internal monitoring tooling in comparison to a classical firewall. NSX relies on external tooling for this. Currently, it is not possible to purchase the NSX firewall (vDefend) as an option to VMware Foundation; it's only available as an option to VCF. Review collected by and hosted on G2.com.

VMware NSX is pretty awesome because it makes managing networks super easy. The integration with other VMware tools is seamless, so you don’t have to worry about compatibility issues. I also love how it beefs up security with features like micro-segmentation—it’s like having a super secure firewall for your network. Plus, the interface is really user-friendly, which makes it easy to navigate even if you're not a networking expert. Review collected by and hosted on G2.com.

Honestly, VMware NSX is cool, but there are a few things that bug me. First off, it’s super expensive. If you’re on a budget or working for a smaller company, the costs can really add up, which kinda sucks.

There’s also just so much stuff in it. Like, having a lot of features is great, but it can get overwhelming really fast. Sometimes it feels like there are too many options, and it makes it harder to figure out what you actually need to use. I wish the interface was simpler or that you could just hide the features you don’t need.

Another thing is that while it usually integrates well with VMware products, it can be a pain when you’re trying to get it to play nice with non-VMware stuff. And when you hit those snags, getting help from support can take forever. It’s frustrating when you’re stuck and just want to get things working again.

So yeah, VMware NSX is powerful, but it’s not without its headaches. Review collected by and hosted on G2.com.

Cloud is not a physical place; It is an operational model. And behind the Cloud operation model, there is automation.

Talking about Cloud without considering network automation (and even security) leaves our "three-legged chair" (computing, storage, and network) without achieving its objective.

And that integrated a stack like VMware Cloud Foundation, which even allows the model to be replicated in Hyperscalers (VMC-A, AVS, GCVE, OCVS), not only simplifies the Day 0 operation, but also Day 2. Review collected by and hosted on G2.com.

Having a console that allows you to coordinately manage the different VMware Cloud environments (VCF, VMC-A, AVS, GCVE, OCVS) would be desirable (as was the NSX+ approach). Firstly for Networking elements, in a second stage extended to Security (vDefend and vDefend with ATP). Review collected by and hosted on G2.com.

I love that it is intuitive. As an IT professional, I like to be able to get to know a product before I recommend it to clients. Review collected by and hosted on G2.com.

Pricing. Not usable for small business, mostly for large clients. Review collected by and hosted on G2.com.

VMware NSX supports automated network provisioning and management, which can significantly reduce the time and effort required to manage network resources. Review collected by and hosted on G2.com.

I have noted that while NSX offers advanced networking features, options like packet acceleration could be improved. This suggests that while NSX is feature-rich, certain advanced capabilities may not be as robust as I expect Review collected by and hosted on G2.com.

They are providing very good customer experience and cloud solutions. If any one want to build a data centre there could not be a better networking solution than VMware NSX. Review collected by and hosted on G2.com.

They are very good in quality but still to get the validation of the quality it will take some time to validate their service better. Other than that it's good. Review collected by and hosted on G2.com.

I have used VMWare NSX for more than 1 year. It is really simple to install and use. Also, really liked the simplicity of the UI. Review collected by and hosted on G2.com.

I did not like that now VMWare NSX is no longer sold as a standalone product. There could've been more options for the users to explore. Review collected by and hosted on G2.com.

granular network segmentation down to the individual workload level. This enhances security by providing isolation and control within the data center Review collected by and hosted on G2.com.

NSX can be quite expensive, especially for smaller organizations. The licensing and operational costs might be a barrier, particularly if you're just starting with network virtualization or have a tight budget. Review collected by and hosted on G2.com.
