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…

Improved bandwidth management and network visibility have resulted in financial benefits and streamlined operations
There is always room for improvement in SolarWinds NetFlow Traffic Analyzer, such as implementing instant reporting based on business intelligence reports and more granular filters in their dashboard to improve the GUI view and reporting. The licensing model of SolarWinds NetFlow Traffic Analyzer is always an issue for users because competitors offer unlimited and perpetual licenses, and SolarWinds NetFlow Traffic Analyzer's model is quite costly compared to other brands. If users are comfortable with SolarWinds NetFlow Traffic Analyzer, they have to make the hard decision to invest, and it's suggested from a user's perspective that SolarWinds should improve their financial model and licensing to become competitive, especially for small to medium businesses.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I have found that it has a good GUI and user-friendly administration."
"The solution offers very good system monitoring; it's easy to manage your network, as well as your hardware and software, and it's really useful."
"The tool's UI is user-friendly, and pricing is affordable. It is very easy to deploy and learn."
"The solution is useful for monitoring network devices."
"The network monitoring feature, especially, stands out to me."
"The initial setup is easy."
"It is highly customizable and can be integrated well with third-party software."
"Since we have been using it for the last five years we have done very well with reference to ROI."
"This tool provides insights into top utilization applications or it identifies which circuit or application is consuming the most on the complete one-gig circuit traffic path."
"NTA's most valuable feature is traffic analysis and visibility."
"The initial setup was straightforward."
"It allows us to pinpoint which protocol is overloading the link."
"As it offers enterprise solutions, it has all the essential features for business."
"Visibility in the network is huge. Using the NetFlow analyzer, along with their NPM and NCM modules, are key for keeping our network up to date and for visibility."
"For managing the traffic, it provides you a response about whether the traffic is down, up, or heavy, which is a very powerful feature. It has a good response time. We have been using this solution for many years, and we don't have any problem with this solution."
"The bandwidth indicates the utilization of the devices; if any issue occurs, it triggers an alert for me."
 

Cons

"They need to have some automation models embedded in them."
"I think the reports can be improved. They're adopted."
"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."
"It has an old-fashioned interface."
"The bandwidth for its front-end version needs enhancement."
"It's very hard to install materials. You need a lot of documentation. They should make it easier to install and configure the solution."
"The graphics and reports can be a little bit better."
"There are some loopholes you need to be aware of from a security perspective."
"There are some areas for improvement in SolarWinds NetFlow Traffic Analyzer. There are some challenges with the solution when compared to other monitoring tools such as difficulty in operations and difficulty with backup installation. My team is currently trying out different solutions but would need to see how it goes."
"SolarWinds' technical support is ok, but it could be faster and more knowledgeable."
"What needs improvement in SolarWinds NetFlow Traffic Analyzer is performance because sometimes, my team struggles too much for the solution to perform correctly for a specific deployment in my organization. Having a more detailed view in SolarWinds NetFlow Traffic Analyzer is another area for improvement, but that's more part of the protocol than the actual solution."
"If your network is on SolarWinds, and you notice that the traffic is bad because it says "user downloading a heavy file," it doesn't indicate which endpoint is downloading those heavy files. SolarWinds doesn't have the tools to be able to handle this kind of situation. You can just notice through your network device that the traffic is becoming overwhelming or heavy, but you cannot go inside and get more details related to the endpoint where it is happening. We would like SolarWinds to be able to handle this kind of situation and even manage the traffic inside a network from the endpoint to the network device. These would be good enhancements. It is mostly stable. The problem comes only when we want to add another SolarWinds model. SolarWinds has so many models, and sometimes when we want to add other models on the platforms that are reserved for our firm, it freezes. When this happens, we have to create a new VM for that model."
"One thing I have noticed is that it is very slow to pick the dynamics of the network, so that is something that could be improved."
"It is scalable, but it could be simplified because it is not completely easy. The price could be reduced to make this product more competitive."
"Technical support is fine but they need to improve their response time."
"The analysis can utilize algorithms like K-means clustering or associative neural networks for predictions rather than relying on generative AI, which is more suited for text."
 

Pricing and Cost Advice

"The solution is cost-efficient."
"I rate Nagios Network Analyzer's pricing a six out of ten."
"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."
"The pricing is really good."
"SolarWinds' pricing structure is the primary reason why some customers opt for another solution such as ManageEngine NetFlow Analyzer. In NTA, you are charged per port, meaning that if you have a 24-port switch you will be charged for 24 individual nodes. ManageEngine NetFlow Analyzer, on the other hand, charges per switch, such that if you add a switch, the entire switch will count as one single node."
"The licensing for this solution is based on the number of nodes."
"Pricing for SolarWinds NetFlow Traffic Analyzer is very high. I have a customer that needs the solution but doesn't have the budget for SolarWinds NetFlow Traffic Analyzer because the problem is that you can't use the solution only. You have to buy requirements such as the SolarWinds NPM first, and some companies don't have the budget for all the required components and modules. SolarWinds NetFlow Traffic Analyzer can cost up to $10,000, and some customers don't have that budget. Another product has all the modules that SolarWinds NetFlow Traffic Analyzer has, with a very low price, that can be a replacement, which is ManageEngine NetFlow Analyzer. PRTG is another solution that can replace SolarWinds NetFlow Traffic Analyzer."
"For our environment, we pay approximately $25,000 USD yearly."
"The pricing is reasonable."
"We pay yearly, and we are happy with its price."
"I don't have information on the licensing cost for SolarWinds NetFlow Traffic Analyzer because it's bundled with another SolarWinds solution. My organization has seven different models and pays for the license yearly. My organization also had to deploy additional pollers, but the cost wasn't very expensive, though I can't give the exact numbers."
