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 solution is stable."
"Flowmon is more easy to understand and helps find network issues more quickly."
"Flowmon is more easy to understand and helps find network issues more quickly."
"It is an open platform, so in terms of integration, we are quite happy. We can integrate it with other SNMP solutions. We can also integrate it with security solutions, such as a SIEM solution."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"It does have capabilities of micro-segmenting a network, being able to create smaller segments of various types of applications separated by various tiers."
"You're building a scalable solution, a secure solution, and a stable end-to-end solution; these are the main measurable benefits VMware NSX provides to the users."
"The security offered by VMware NSX is the most valuable, plus it's a feature-rich product that's straightforward to install and configure."
"It's very important for them to have small footprints and have as much services in their servers, as possible."
"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."
"From a distributed firewall perspective, it's a solid solution."
"The most powerful feature of VMware NSX is the micro-segmentation that allows us to separate the different protocols our application works with."
"This solution comes with an API that can easily integrate with other solutions."
 

Cons

"The licensing price could be better."
"If there was better visualization in Flowmon Solution it would be good."
"I do not know the detailed pricing."
"It would be helpful to have more details about the monitoring of the infrastructure. It should have support for SNMP. This is something that is currently not there in the product."
"One drawback is this solution requires a lot of other products in the VMware ecosystem to have a full end-to-end operation orchestration monitoring. You have to buy a lot of add-ons to fully utilize the functionality."
"The price could be better. The non-enterprise version of the product should also be improved. I would like VMware to expand beyond the network and provide some VLAN technologies and more. I think we have one, but it's more on the distribution side because it's more on the upper side of the network. I'm looking forward to that."
"The solution is only sold as part of a bundle and not as an individual product."
"The setup is complex and should be made easier."
"VMware NSX could improve by having more compatibility with other none Window-based operating systems."
"The licensing model is expensive and could be more flexible, especially after Broadcom bought VMware."
"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."
"There were some issues with finance and other accounting."
 

Pricing and Cost Advice

"The licensing fee accrues only once, but that of support is annual."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"The price of the solution could be better."
"We can't go without NSX, so it's invaluable from this perspective."
"The price of VMware NSX is very good compared to other solutions."
"The solution is free and the price for the support can be expensive."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"The tool's pricing is reasonable."
"It is an expensive product, but cheaper than some competing solutions."
"We are using a perpetual license to use the solution and we have support."
