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 product's initial setup phase was really easy."
"We've been completely satisfied with the product."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"We use it to protect our users and their data."
"The solution is very user-friendly and very easy to use."
"The most valuable feature is the cloud DDoS scrubbing capability."
"The protection resources and the support are valuable features of the solution."
"The product allows the users to adjust the thresholds."
"From my experience, VMware on a private cloud is a good choice."
"To be able to do the DR and SRM migrations from datacenter to datacenter, we're able to do them with SRM with VXLAN, with the NSX product."
"The most valuable features are its security aspects, especially the IPS and IDS for intrusion detection and protection."
"VMware NSX has the ability to create networks in software."
"We have many advantages with the cloud infrastructure."
"Our clients are very satisfied that we can limit ourselves to NSX without the need to purchasing additional network systems and physical devices."
"The most valuable feature is to control application behavior, and it provides us with features that other products have not."
"Consistent networking and security policies across different environments have a major and very positive impact on our business operations, allowing us to achieve the security posture we want with compliance and regulations."
 

Cons

"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The solution can be a little more user-friendly and it can be more affordable."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The product’s pricing needs improvement."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"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."
"It should be more adapted to the physical side of network topology in order to prevent unavailability."
"Its licensing model could be VM based."
"Going through and getting more features sets from the routing protocols is definitely necessary for the future."
"Tech support is nice. It could be a little bit better."
"It still needs to grow. There are still some features that it doesn't do, like it doesn't do multicasting."
"There is room for improvement in VMware NSX's workload management, particularly in the orchestration layer and in managing workloads across multiple clouds."
"The feature it can improve is essentially application-based load balancing with intelligent load distribution for applications that require redundancy and high availability."
 

Pricing and Cost Advice

"It's quite pricey."
"The solution is reasonably priced."
"The product’s pricing needs improvement."
"If five is a good price and one is a high price, I would rate the price a one out of five."
"The licensing fees are expensive and we pay on a yearly basis."
"We have saved man-hours and decreased our security exposure."
"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."
"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."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
"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."
"The subscription is on a yearly basis."
