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 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."
"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."
"The solution is stable."
"If people or users are complaining that the network is slow, Flowmon can easily detect the cause of the network problem."
"Flowmon is more easy to understand and helps find network issues more quickly."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every type of customer, such as government and commerce."
"VMware NSX is a great product for network virtualization, and it's great for enhancing security at the virtual machine level."
"The most valuable features for us at this early stage are the interface and the integration with existing VMware solutions."
"The we can actually extend Layer 2 networking across datacenters, and also Layer 3 networking, which comes along with it."
"It's changed the way we do things."
"VMware NSX is used for micro-segmentation, and if you have a virtual VMware pool then you can segment them separately, similar to a firewall for virtual micro-segmentation."
"The solution is very stable; there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
"The micro-segmentation and the ability to create policy rules are valuable."
"What makes them unique is their range of discovery, the way they can effectively mimic actual PC or smartphone endpoints to examine malware behavior."
 

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."
"If there was better visualization in Flowmon Solution it would be good."
"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."
"The licensing price could be better."
"Occasionally the licensing is not very clear. They should make it easier to understand."
"The product is quite complex and that could be an area where improvements could be made."
"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."
"We've have had good and bad experiences with them. We don't always find them to be so impactful. Sometimes the support guy isn't so on top of resolving the issue and it can take a while to sort out."
"Sometimes we face issues when a server is compromised or we have an infection. The isolation feature helps, but we need to work more on this aspect."
"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."
"I would like them to make integration with other vendors easier."
"They need to enhance their technical support. There is no comparison between VMware technical support and Cisco's technical support."
 

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 price of the solution could be better."
"The licensing fee accrues only once, but that of support is annual."
"I would rate the pricing of VMware NSX as seven out of ten"
"We have saved man-hours and decreased our security exposure."
"We haven't had to hire a dedicated network engineer because NSX handles 90 percent of it. The reduced overhead in terms of managing networks has been the biggest plus."
"The solution is very expensive."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
"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."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
