Improves network security with micro-segmentation but setup is complex
I value the ability to dynamically configure our network on the fly using VMware NSX. This flexibility is a huge advantage because it allows us to avoid static configurations that come with traditional hardware setups. Additionally, the micro-segmentation feature is beneficial for adhering to strict security regulations from our security department.

"The solution is stable."

"The most valuable features are the micro-segmentation and integrated security options."
"Firewall security is one of VMware NSX's vital features"

"The most valuable feature is the integration with the firewall."
 

Cons

"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."
"The licensing price could be better."
"The initial configuration and integration within our existing environment were not easy. The configuration process was a bit complex, specifically during the initial setup."
"There are sometimes mismatch in the control, the details and what you actually see on the transport note."
"The solution is complex but for the key user, it's not really complex. You just need to learn the standards and mechanics for your specific product."
"The solution is only sold as part of a bundle and not as an individual product."
"The ticket support response time from VMware could be improved. Often, callbacks are delayed, which can be problematic if the servers are in production."
"We had some complexities implementing into the other parts of a network."
"One drawback is this solution requires a lot of other products in the VMware ecosystem to have a full end-to-end operation orchestration monitoring. You have to buy a lot of add-ons to fully utilize the functionality."
"The initial configuration and integration within our existing environment were not easy."
 

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 solution is reasonable at the local level."
"The tool's pricing is reasonable."
"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."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"The implementation of VMware NSX can be cost-intensive, especially if an organization is looking for a comprehensive solution. The costs can vary based on factors like the level of conversation and discounts obtained during negotiations. Some government organizations, for instance, may find the prices relatively high, leading to concerns about budget hikes, especially when deploying the solution across the entire organization. Regarding maintenance and support, they are typically included in the standard licensing costs for enterprise-level businesses. While these costs can be significant, many companies opt for standard licensing to ensure they have access to necessary support and maintenance services."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"VMware has always been geared towards enterprise and their pricing options are a bit high. Their price is higher than other options in the market."
