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

"A great feature is the memory utilization graph."
"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."
"We have a good relationship with NETSCOUT, and it's reflected in the communication and the service that we see from them."
"The most valuable feature of VMware NSX is the high bandwidth."
"If the new user is looking for micro-segmentation in the network space, then VMware NSX is the best solution."
"Load balancing is achieved using VMware NSX."
"We have deployed it in a virtual environment and it saved a lot of time and effort for us to configure."
"They have a lot of support and specialists who can meet with the customer."
"One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore."
"It's very effective in how easy it is to manage and orchestrate all the different devices with the different types of requirements we have."
"The ease in which to install this product and make it work straight away without minimum changes in your physical network is simply astonishing."
 

Cons

"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."
"Sometimes the network analyzer will show that a server is down when it's actually working."
"We have done three installations and we have not had any critical issues. The time it took for the installation was approximately two days. However, they should provide better documentation."
"The price is rather high."
"It's a good product, but the way that it has got so many multiple levels that need to be purchased makes it expensive and cumbersome."
"The setup of the solution could be simplified."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"VMware NSX can improve the migration tools from the older environments to the new environment."
"I would like to have automating reporting built into common service management platforms, such as JIRA, Serviceaide, and ServiceNow."
"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."
 

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."
"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."
"We are using a perpetual license to use the solution and we have support."
"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."
"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 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 solution is reasonable at the local level."
"It is an expensive product, but cheaper than some competing solutions."
"I'm unable to give information on the pricing or licensing cost of VMware NSX because I've never been someone who looks into the economic part of any security or virtualization solutions. That's handled by an entirely different team, and I don't even have the slightest idea about the costs associated with the solution, though I've heard pricing for VMware NSX is on the higher side."
