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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The initial setup is easy."
"It is highly customizable and can be integrated well with third-party software."
"The solution offers very good system monitoring; it's easy to manage your network, as well as your hardware and software, and it's really useful."
"Its initial setup process is straightforward."
"I have found that it has a good GUI and user-friendly administration."
"The solution is useful for monitoring network devices."
"The network monitoring feature, especially, stands out to me."
"Our customers like this product due to the fact that it's quite simple and it can be integrated with other solutions that complement and complete each other."
"It is a stable solution...The solution's initial setup process was easy."
"The best part is the blueprint creation where I can create their things and then move on to the target environment."
"The solution is easy to use and is good for management control."
"The most valuable features for us at this early stage are the interface and the integration with existing VMware solutions."
"The most valuable features are the micro-segmentation and integrated security options."
"I value the ability to dynamically configure our network on the fly using VMware NSX."
"NSX is extremely invaluable from the standpoint of security."
"We are using VMware NSX for all our network needs."
 

Cons

"I think the reports can be improved. They're adopted."
"It has an old-fashioned interface."
"The graphics and reports can be a little bit better."
"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."
"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 bandwidth for its front-end version needs enhancement."
"They need to have some automation models embedded in them."
"There are some loopholes you need to be aware of from a security perspective."
"There could be an improvement in regards to security. This solution cannot migrate all assets smoothly and continuously, for example, sometimes the physical hosts are not able to be converted into virtual ones, which needs to be fixed."
"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."
"It's not feature-rich."
"I would like them to make integration with other vendors easier."
"VMware NSX can improve the migration tools from the older environments to the new environment. For example, the NSX-V has become a legacy solution, it's out of support, but customers are able to keep using it. For migration purposes, it's better for them to provide a proper tool. It will be easy to migrate from an old environment to a new one."
"They need to enhance their technical support. There is no comparison between VMware technical support and Cisco's technical support."
"VMware NSX provides a lot of automation capabilities, but there is still room for improvement."
"If you compare NSX to a similar solution you might find it to be a bit more complex."
 

Pricing and Cost Advice

"I rate Nagios Network Analyzer's pricing a six out of ten."
"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."
"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."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
"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."
"The cost of the solution is a bit high."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"There is a license required for this solution, we pay annually."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
"We are using the free version of the solution."
