The solution is useful for monitoring network devices, but the interface is old-fashioned
The solution is useful for monitoring network devices We use it for up-and-down monitoring features. It’s an old solution. It has an old-fashioned interface. The product must provide a compliance testing feature. I have been using the solution for six years. I rate the tool’s stability a ten…

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

"Since we have been using it for the last five years we have done very well with reference to ROI."
"The network monitoring feature, especially, stands out to me."
"Network tracking is the most valuable feature of Network Analyzer."
"I have found that it has a good GUI and user-friendly administration."
"The tool's UI is user-friendly, and pricing is affordable. It is very easy to deploy and learn."
"Our customers like this product due to the fact that it's quite simple and it can be integrated with other solutions that complement and complete each other."
"Its initial setup process is straightforward."
"It is highly customizable and can be integrated well with third-party software."
"Every time my coworker talks to customer support, they're easy to get a hold of, very knowledgeable, and they solve his issues right away."
"The solution is very stable; there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
"The ability to scale from different clouds. At the moment, the scalability of the product is the number one thing that I saw."
"It has reduced the number of people on the network team along with the system engineer involved in the security process, so it is valuable and we can't go without NSX, so it's invaluable from this perspective."
"This product is better for network security than Cisco ASA and Firepower."
"The alert features are the most valuable."
"What makes them unique is their range of discovery, the way they can effectively mimic actual PC or smartphone endpoints to examine malware behavior."
"The most valuable feature is to control application behavior, and it provides us with features that other products have not."
 

Cons

"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."
"I think the reports can be improved. They're adopted."
"They need to have some automation models embedded in them."
"The bandwidth for its front-end version needs enhancement."
"The graphics and reports can be a little bit better."
"It's very hard to install materials. You need a lot of documentation. They should make it easier to install and configure the solution."
"It has an old-fashioned interface."
"There is room for improvement on the setup side."
"VMware NSX can improve the migration tools from the older environments to the new environment."
"There are sometimes mismatch in the control, the details and what you actually see on the transport note."
"Some disadvantages of VMware NSX include a price challenge due to the high licensing cost compared to competitors, and it may sometimes require a specific skill set."
"Lastline is not a cheap product if compared with their competitors."
"The product is quite complex and that could be an area where improvements could be made."
"Migrating from V to T is very tricky, complicated, and there are a lot of parameters to account for."
"It takes time to do the initial setup. It is a bit slow, which is surprising."
"It could be cheaper!"
 

Pricing and Cost Advice

"The solution is cost-efficient."
"They charge around ten thousand per month for one thousand nodes. That is their overall cost, but it differs on which company you are applying to, whether you are a service provider or an enterprise."
"I rate Nagios Network Analyzer's pricing a six out of ten."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"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."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"The pricing model for VMware NSX is good."
"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."
"This solution requires a licence."
"There is a license required for this solution, we pay annually."
"The licensing fees are expensive and we pay on a yearly basis."
