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

"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 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."
"We are happy with the scalability."
"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."
"I rate the scalability as ten out of ten."
"The ability to scale from different clouds. At the moment, the scalability of the product is the number one thing that I saw."
"Overall, I would say the solution has been quite stable."
"VMware NSX is a very good solution. It's also a scalable solution."
"VMware NSX offers some of the best features for security, such as micro-segmentation."
"The most powerful feature of VMware NSX is the micro-segmentation that allows us to separate the different protocols our application works with."
 

Cons

"If there was better visualization in Flowmon Solution it would be good."
"I do not know the detailed pricing."
"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."
"The setup of the solution could be simplified."
"The ticket support response time from VMware could be improved. Often, callbacks are delayed, which can be problematic if the servers are in production."
"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."
"We have done three installations and we have not had any critical issues. The time it took for the installation was approximately two days. However, they should provide better documentation."
"Quite a complex solution."
"An area for improvement in VMware NSX is that it uses up more resources and is heavy on the network. What I'd like to see in the next release of the solution is more automation."
"The vendor should integrate a basic load balancer in future versions"
"I want to see the solution expand to more than just the network, for example, perhaps it could provide some VLAN technologies."
 

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."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"The solution is free and the price for the support can be expensive."
"We are using the free version of the solution."
"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."
"The price of VMware NSX is very good compared to other solutions."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"The cost of the solution is a bit 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."
