Gilbert Mwiinga - PeerSpot reviewer
Effectively monitors the uptime of all equipment and network connectivity
There is room for improvement on the setup side. It's not very user-friendly, especially for those who aren't tech-savvy. I find it a bit hard to set up initially. It could be done better to make it easier to configure. It would be beneficial for users. For additional features, I have an idea. I'm not sure if it's already there, but it would be great to have a feature that maps the network and shows which devices are connected. It could provide information about how traffic flows and offer a visual representation of how devices are physically connected to each other. It would be like a network audit feature that displays the connections between switches and other devices. So, in future releases, a network mapping and visualization feature would be valuable.

DanielBass - PeerSpot reviewer
Improves network security with micro-segmentation but setup is complex
I value the ability to dynamically configure our network on the fly using VMware NSX. This flexibility is a huge advantage because it allows us to avoid static configurations that come with traditional hardware setups. Additionally, the micro-segmentation feature is beneficial for adhering to strict security regulations from our security department.

"It is highly customizable and can be integrated well with third-party software."
More Nagios Network Analyzer pros
"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."
"Technically, VMware NSX is more advanced technology-wise when compared to others. We have been studying it and so far, so good. We know that the NSX product is superior when it comes to software virtualized networks. </p> <p>If you are looking to work with new and future technologies, then NSX is one of the best options. It costs less for power consumption since it will be a virtual network and not a pure physical network that consumes more energy."
"The most valuable feature of VMware NSX is the load balancing and routing of firewall rules. Many of the features are beneficial."
"The micro-segmentation and the ability to create policy rules are valuable."
"The product has valuable features for security and network extension."
"Their technical support is very good. They help us figure out solutions when we have problems."
"It's very important for them to have small footprints and have as much services in their servers, as possible."
More VMware NSX pros
 

Cons

"They need to have some automation models embedded in them."
"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."
"There is room for improvement on the setup side."
"It has an old-fashioned interface."
"The graphics and reports can be a little bit better."
"It's very hard to install materials. You need a lot of documentation. They should make it easier to install and configure the solution."
"I think the reports can be improved. They're adopted."
"There are some loopholes you need to be aware of from a security perspective."
More Nagios Network Analyzer cons
"The training costs a minimum of $3,000, which is expensive and should be reduced."
"The feature it can improve is essentially application-based load balancing with intelligent load distribution for applications that require redundancy and high availability."
"I would like them to make integration with other vendors easier."
"This solution is really unusable from my perspective at this point. Overall, I would rate the solution a one of ten."
"There are sometimes mismatch in the control, the details and what you actually see on the transport note."
"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."
"There were some issues with finance and other accounting."
"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."
More VMware NSX cons
 

Pricing and Cost Advice

"The solution is cost-efficient."
"They charge around ten thousand per month for one thousand nodes. That is their overall cost, but it differs on which company you are applying to, whether you are a service provider or an enterprise."
"I rate Nagios Network Analyzer's pricing a six out of ten."
"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."
"It is an expensive product, but cheaper than some competing solutions."
"The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"We can't go without NSX, so it's invaluable from this perspective."
"The price could be better. We pay for the license every three years. The last time I checked, it cost around three million pesos in the Philipines. Most of the expense will go towards implementation and renovation."
"All the institutions have to pay monthly for the services in the cloud. They have to pay $30,000 every month for this service every three years."
