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.

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.

More VMware NSX pros

Cons

"There is room for improvement on the setup side."

"I think the reports can be improved. They're adopted."

"There are some loopholes you need to be aware of from a security perspective."

"The bandwidth for its front-end version needs enhancement."

"It's very hard to install materials. You need a lot of documentation. They should make it easier to install and configure the solution."

"The graphics and reports can be a little bit better."

"They need to have some automation models embedded in them."

"It has an old-fashioned interface."

More Nagios Network Analyzer cons

"There is room for improvement in VMware NSX's workload management, particularly in the orchestration layer and in managing workloads across multiple clouds."

"I would rate NSX's stability eight out of ten - there's room for improvement."

"We would to have a reverse proxy. This would add great value to the solution."

"This solution is really unusable from my perspective at this point. Overall, I would rate the solution a one of ten."

"There are always issues integrating with Cisco."

"It was stable for one year, there was no impact. In the last two months, we had two big incidents."

"NSX could better integrate with open-source products. Of course, it integrates with some, but I know many people are uncomfortable deploying NSX with certain open-source solutions, such as Radar."

"In the next release, they should enhance the visual interface. With NSX-T, it's difficult to communicate between the public cloud and the container."

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."

"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."

"We can't go without NSX, so it's invaluable from this perspective."

"There is a license required for this solution, we pay annually."

"There is a license required for this solution and there is also a support license available. The price of the solution could be better."

"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."

"I would rate the pricing of VMware NSX as seven out of ten"

"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."
