Micro segmentation has strengthened zero trust security and isolates production from test environments
The advantages of VMware NSX include its micro-segmentation for internal security at the firewall and VM levels, which is very powerful and helps us comply with complete Zero Trust security models. We are able to achieve this and configure network level virtualization with no dependency on VLANs. Micro-segmentation helps improve our security significantly. We are not totally dependent upon our physical upfront firewall, and it makes sense to configure everything using VMware NSX, leading to multiple improvements in our organization. We moved from traditional networking such as VLANs from the firewall and switches to VMware NSX segmentation. We achieve one firewall per VLAN and can stop lateral movement such as ransomware control. The Zero Trust model is the main functionality and architecture it offers, allowing application isolation, such as having a separate production and test environment. Consistent networking and security policies across different environments have a major and very positive impact on our business operations, allowing us to achieve the security posture we want with compliance and regulations.

"The solution is both stable and scalable and we are happy with the product."
"Flowmon is more easy to understand and helps find network issues more quickly."
"With Lastline, the effort to put in into the protecting the users against zero-day threats and malware can be subsequently reduced."
"This product is like the layer between traditional networking and virtualization, giving you the flexibility to deploy and have network virtualization on different types of firewalls."
"It gives more security and micro-segmentation. It helps to set network configurations in an easy way."
"One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore."
"The most valuable feature is to control application behavior, and it provides us with features that other products have not."
"NSX has excellent security features like virtual firewalls. I also like the micro-segmentation features, which are useful for the virtual machines inside the servers."
"They have a lot of support and specialists who can meet with the customer."
"Has a great firewall."
 

Cons

"The price of the license could be lower."
"If there was better visualization in Flowmon Solution it would be good."
"It would be helpful to have more details about the monitoring of the infrastructure. It should have support for SNMP. This is something that is currently not there in the product."
"I do not know the detailed pricing."
"It's a good product, but the way that it has got so many multiple levels that need to be purchased makes it expensive and cumbersome."
"It's not feature-rich."
"I would like to see automation capabilities in the deployment process."
"The setup of the solution could be simplified."
"Speed of the NSX Controllers while deploying sometimes gets a bit slower which can be improved, overall its a great product"
"We would to have a reverse proxy. This would add great value to the solution."
"The vendor should integrate a basic load balancer in future versions"
"VMware NSX should be able to scale for different customers, even the big ones. Its scalability needs improvement. Stability for it should also be improved."
 

Pricing and Cost Advice

"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"The licensing fee accrues only once, but that of support is annual."
"The price of the solution could be better."
"The price is significantly high and it can be a hurdle for many potential users."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"The price could be better. We pay for the license every three years. The last time I checked, it cost around three million pesos in the Philipines. Most of the expense will go towards implementation and renovation."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"We can't go without NSX, so it's invaluable from this perspective."
"We are using a perpetual license to use the solution and we have support."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
