Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.

"The solution is stable."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"The solution is both stable and scalable and we are happy with the product."
"It is an open platform, so in terms of integration, we are quite happy. We can integrate it with other SNMP solutions. We can also integrate it with security solutions, such as a SIEM solution."
"NSX helps us by making IT management and operations more efficient. When VMs spin off from the DC to the DR site, all required settings on the network level are handled automatically."

"It's very important for them to have small footprints and have as much services in their servers, as possible."
"It gives more security and micro-segmentation. It helps to set network configurations in an easy way."
"I have found VMware NSX to be easy to use."
"Though I haven't been working a lot on VMware NSX, it's good to have. What I like the most about it is that its console is good, and it doesn't take a lot of effort in terms of doing my daily tasks on it or what it's meant for. VMware NSX is still a preferred product in the market."
"Apart from the normal functionality, a few things are quite useful, including multi-cloud networking, container networking, and load balancing, which are quite useful when we are designing a solution, and it's a pretty mature platform right now."
"The organization of it is logical, useful, and intuitive."
 

Cons

"If there was better visualization in Flowmon Solution it would be good."
"The price of the license could be lower."
"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 NSX setup is complex. That's one area where they could improve."
"Some disadvantages of VMware NSX include a price challenge due to the high licensing cost compared to competitors, and it may sometimes require a specific skill set."
"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."
"In some cases, we had to uninstall and install from scratch NSX and restore from backup, which in a real world scenario won't be desirable to do."
"It might be nice to have more AI in the future."
"They have to work more and more on the integration for public cloud services and have cyber security platform integration."
"I have no complaints regarding the user interface or any technical issues."
"The first time setting it up was difficult."
 

Pricing and Cost Advice

"The licensing fee accrues only once, but that of support is annual."
"The price of the solution could be better."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"Our customers have definitely complained about its cost. It's expensive. I'd rate it a nine out of ten in terms of pricing where ten represents a high price. There are other products out there that are equally expensive."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"The solution is reasonable at the local level."
"We are using a perpetual license to use the solution and we have support."
"There is a license required for this solution, we pay annually."
