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

"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 solution is both stable and scalable and we are happy with the product."
"The solution is stable."
"If people or users are complaining that the network is slow, Flowmon can easily detect the cause of the network problem."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"Flowmon is more easy to understand and helps find network issues more quickly."
"The most valuable features are stability and low cost."
"NSX extends Layer-2 scalability on Layer 3, covering the vRO and extending the capability on Layer 3 by decapsulating using a new mechanism."
"It's what we use the CIS Benchmarks for. It's for employing hardening rules and keeping them up to date when things happen on our systems. So it's really configurations and stuff that harden and report back."
"Though I haven't been working a lot on VMware NSX, it's good to have. What I like the most about it is that its console is good, and it doesn't take a lot of effort in terms of doing my daily tasks on it or what it's meant for. VMware NSX is still a preferred product in the market."
"It's very important for them to have small footprints and have as much services in their servers, as possible."
"We are using VMware NSX for all our network needs."
"It operates on a logical level, providing a comprehensive and centralized way to manage your network resources."
"With Lastline, the effort to put in into the protecting the users against zero-day threats and malware can be subsequently reduced."
 

Cons

"If there was better visualization in Flowmon Solution it would be good."
"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."
"The price of the license could be lower."
"I do not know the detailed pricing."
"The support from VMware NSX could improve."
"NSX could better integrate with open-source products. Of course, it integrates with some, but I know many people are uncomfortable deploying NSX with certain open-source solutions, such as Radar."
"It lacks full knowledge of physical side of the network topology."
"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."
"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."
"Despite being somewhat behind in the cybersecurity field, VMware should develop a cloud and a red team to continuously monitor for new malware and ransomware."
"The solution is only sold as part of a bundle and not as an individual product."
"In the next release, they should enhance the visual interface. With NSX-T, it's difficult to communicate between the public cloud and the container."
 

Pricing and Cost Advice

"The licensing fee accrues only once, but that of support is annual."
"The price of the solution could be better."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"The tool's pricing is reasonable."
"We have saved man-hours and decreased our security exposure."
"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."
"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."
"It is an expensive product, but cheaper than some competing solutions."
"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."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
