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.

Quotes from Members

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

Pros

"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"Flowmon is more easy to understand and helps find network issues more quickly."
"Flowmon is more easy to understand and helps find network issues more quickly."
"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."
"The solution is stable."
"I have found VMware NSX to be easy to use."
"The installation is straightforward, it took a couple of hours."
"The firewall is its most valuable feature."
"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 features of VMware NSX are the tight integration with the VMware Hypervisor natively and the management console. We have a lot of other integrations where you are able to see the virtual machine's end-to-end visibility."
"Their technical support is very good. They help us figure out solutions when we have problems."
"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."
"During our experience, the solution has been stable."
 

Cons

"The licensing price could be better."
"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."
"If there was better visualization in Flowmon Solution it would be good."
"I do not know the detailed pricing."
"It was stable for one year, there was no impact. In the last two months, we had two big incidents."
"It still needs to grow. There are still some features that it doesn't do, like it doesn't do multicasting."
"The initial establishment can be complex."
"The tool's setup is complex and we need support to implement it."
"I would rate this product an eight because it's a good product but it needs more work. They should fix some of the bugs."
"VMware NSX provides a lot of automation capabilities, but there is still room for improvement."
"If you're worried that NSX is too complex, I would tell you to take another look. If you compare NSX to a similar solution you might find it to be a bit more complex. Usually, the guy that comes in to implement NSX isn't the network guy and will lack the knowledge for the program. He can lack the knowledge for this program and will therefore think it's complex. You need somebody with network experience."
"This solution is really unusable from my perspective at this point. Overall, I would rate the solution a one of ten."
 

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."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
"The price of this product is too high."
"I'm unable to give information on the pricing or licensing cost of VMware NSX because I've never been someone who looks into the economic part of any security or virtualization solutions. That's handled by an entirely different team, and I don't even have the slightest idea about the costs associated with the solution, though I've heard pricing for VMware NSX is on the higher side."
"VMware NSX isn't cheap."
"I would rate the pricing of VMware NSX as seven out of ten"
"The solution is reasonable at the local level."
"The price is pretty high."
"We have saved man-hours and decreased our security exposure."
