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.

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

"Flowmon is more easy to understand and helps find network issues more quickly."
"The solution is stable."
"We secured our organisation with Micro-segmentation."
"It's very important for them to have small footprints and have as much services in their servers, as possible."

Cons

"If there was better visualization in Flowmon Solution it would be good."
"The licensing price could be better."
"I do not know the detailed pricing."
"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 have no complaints regarding the user interface or any technical issues."
"A room for improvement in VMware NSX is that it has some security vulnerabilities, which means my company has to apply the patches every once in a while."
"I want to see the solution expand to more than just the network, for example, perhaps it could provide some VLAN technologies."
"It could be more user-friendly, but it's manageable. When we add a specific node to this particular NSX and the configuration changes, it won't push through the errors where required, but it'll accept it. However, while using it, we will have issues. It can also be more stable."
"The tool's setup is complex and we need support to implement it."
"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."
"The reporting functionality could be better, and there could be an easier way of forwarding events. There's room for improvement in the product."
"They have to work more and more on the integration for public cloud services and have cyber security platform integration."
 

Pricing and Cost Advice

"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."
"The licensing fee accrues only once, but that of support is annual."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"The price of this product is too high."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"If five is a good price and one is a high price, I would rate the price a one out of five."
"VMware NSX isn't cheap."
"The licensing fees are expensive and we pay on a yearly basis."
"The cost of the solution is a bit high."
"We are using the free version of the solution."
