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.

Pricing and Cost Advice

"I rate Nagios Network Analyzer's pricing a six out of ten."
"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."
"The solution is cost-efficient."
"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 licensing fees are expensive and we pay on a yearly basis."
"We are using the free version of the solution."
"VMware has a subscription and perpetual license. In the New Year, they're changing many things about the licensing model. Previously, NSX was licensed according to the number of sockets inside the appliance, so we bought VMware licenses based on that. However, that may have changed this year. We are still contacting the vendors to understand the new licensing strategy."
"VMware NSX isn't cheap."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"The pricing model for VMware NSX is good."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
