Provides a memory utilization graph and shows disk space and uplink utilization but could include smart navigation in next release
The solution is deployed on-premises. There are more than 20 people who use this solution in my organization. They're infrastructure engineers, network engineers, and information security engineers A great feature is the memory utilization graph. It shows utilization, disk space utilization,…

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 feature that I have found the most useful is the decode of packets. It gives us a variety of information that helps us in figuring out what to look at. The networks are getting really complex, and without the information that we get from Iris Session Analyzer, we couldn't do our job. Its graphical user interface is also very easy to use and intuitive."
"A great feature is the memory utilization graph."
"I really like the management dashboard, the tailor-made assurance, the telemetry, and the ease of integration with all other solutions of VMware, such as vSphere."
"When you have a solid secure solution between your on-prem and cloud solution, then you're in a safe place."
"The most valuable features are stability and low cost."
"The solution's customer service is good."
"You can easily integrate this with other VMware products. It is a robust solution."
"The microsegmentation is great, and the security team thinks it is great."
"VMware NSX is a very good solution. It's also a scalable solution."
"We are happy with the scalability."
 

Cons

"Sometimes the network analyzer will show that a server is down when it's actually working."
"They can increase flexibility in the search engine. Basically, I go with the information I have at the time. If I could just type in the parameter that I want to search for and its value, it might be easier than having to do the groundwork upfront before I can get my traces."
"The solution is quite complex. You need to keep your thinking cap on and know what you are doing: Go to the training and listen to the solution architects when they come in because they have a lot of knowledge."
"I want to see the solution expand to more than just the network, for example, perhaps it could provide some VLAN technologies."
"One aspect that needs improvement is the need for further automation."
"Since most people are very much used to physical networking, they find it difficult to use VMware NSX in the initial stage."
"Our technical team is always looking for the solutions that they work with to offer more convenient integrations."
"I think that one of the more important things to see better integrated into the NSX product would be an IDS/IPS type solution."
"VMware NSX could improve by having more compatibility with other none Window-based operating systems."
"They have to work more and more on the integration for public cloud services and have cyber security platform integration."
 

Pricing and Cost Advice

"I don't know what the cost to buy the solution was, but I doubt if it's a significant part of the budget as far as the maintenance and support are concerned."
"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."
"We can't go without NSX, so it's invaluable from this perspective."
"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."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"The price of VMware NSX is optimal. Additionally, the price of the solution can be negotiated with the vendor. Many areas of the solution can impact the cost, such as features, time for onboarding, and support needed."
"It is an expensive product, but cheaper than some competing solutions."
"The pricing model for VMware NSX is good."
"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."
