The solution is useful for monitoring network devices, but the interface is old-fashioned
The solution is useful for monitoring network devices We use it for up-and-down monitoring features. It’s an old solution. It has an old-fashioned interface. The product must provide a compliance testing feature. I have been using the solution for six years. I rate the tool’s stability a ten…

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.

"NSX gives us the ability to put our network, NSX, onto any network there is, which allows us not to have to go to the network team to create networks or VLANs for networks, and we can just create all our networks right from the start."
 

Cons

"I think the reports can be improved. They're adopted."
"The bandwidth for its front-end version needs enhancement."
"The graphics and reports can be a little bit better."
"They need to have some automation models embedded in them."
"It's very hard to install materials. You need a lot of documentation. They should make it easier to install and configure the solution."
"There are some loopholes you need to be aware of from a security perspective."
"There is room for improvement on the setup side."
"It has an old-fashioned interface."
"It's not feature-rich."
"NSX V has less security features than NSX T just so you are aware"
"I would rate this product an eight because it's a good product but it needs more work. They should fix some of the bugs."
"I would like to see automation capabilities in the deployment process."
"The routing functionality needs to be improved, as there are lots of bugs in the system."
"The setup of the solution could be simplified."
"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 product is quite complex and that could be an area where improvements could be made."
 

Pricing and Cost Advice

"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."
"I rate Nagios Network Analyzer's pricing a six out of ten."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
"The pricing model for VMware NSX is good."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
"The price of this product is too high."
"It is an expensive product, but cheaper than some competing solutions."
"If five is a good price and one is a high price, I would rate the price a one out of five."
"The implementation of VMware NSX can be cost-intensive, especially if an organization is looking for a comprehensive solution. The costs can vary based on factors like the level of conversation and discounts obtained during negotiations. Some government organizations, for instance, may find the prices relatively high, leading to concerns about budget hikes, especially when deploying the solution across the entire organization. Regarding maintenance and support, they are typically included in the standard licensing costs for enterprise-level businesses. While these costs can be significant, many companies opt for standard licensing to ensure they have access to necessary support and maintenance services."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
