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

"The solution is useful for monitoring network devices."
"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."
"Network tracking is the most valuable feature of Network Analyzer."
"This is a product that I can recommend."
"Its initial setup process is straightforward."
"I have found that it has a good GUI and user-friendly administration."
"The network monitoring feature, especially, stands out to me."
"Since we have been using it for the last five years we have done very well with reference to ROI."
"I find this tool very helpful in identifying the top traffic paths from source to destination, and determining which routes are consuming the most resources."
"I like the solution because it has good documentation and training online."
"The bandwidth monitoring functionality is one of the most important features for our customers. When the customer notices that their bandwidth usage is too high for some reason, they will use the traffic analysis within SolarWinds NTA to identify which protocols (e.g. HTTPS) or applications are using up the bandwidth."
"It is used on a daily basis and it is one of the key tools that we use to maintain our network and keep track of our infrastructure."
"It is great at telling you if your devices are working and it keeps an eye on your network's overall performance."
"I like that it is able to monitor multiple devices and it's vendor-agnostic."
"What the network team found most valuable in SolarWinds NetFlow Traffic Analyzer is that it helps them to troubleshoot or analyze the issue. For example, traffic that comes from our location: India, goes to the US, so for the network team to analyze where the traffic comes from and where it is directed, and whether the packets are being dropped, they use SolarWinds NetFlow Traffic Analyzer. The network team also likes that through the solution, they can analyze the complete traffic utilization and how they're going to use it. SolarWinds NetFlow Traffic Analyzer is user-friendly. The team finds it comfortable to use."
"The product is a great experience to use and I never experienced any problems with this software application."
 

Cons

"I think the reports can be improved. They're adopted."
"It's very hard to install materials. You need a lot of documentation. They should make it easier to install and configure the solution."
"There is room for improvement on the setup side."
"There are some loopholes you need to be aware of from a security perspective."
"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."
"It has an old-fashioned interface."
"They need to have some automation models embedded in them."
"The graphics and reports can be a little bit better."
"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."
"NTA's documentation for the implementation phase needs some enhancement."
"I would like to see more training videos and additional material for learning how to use this solution."
"There is a lack of documentation ......as well as a lack of dashboards."
"Deployment needs improvement. The process is complicated, requiring attention to infrastructure settings and installation of components like the origin application server, platform, close storage, and policy agents."
"The plotting of the device on the map is not appropriate."
"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 area that we struggle with is the price. Because the price of this solution is so high, we are largely unable to introduce it into the local market, and only the banking sector has the means to afford it."
 

Pricing and Cost Advice

"I rate Nagios Network Analyzer's pricing a six out of ten."
"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."
"We have licenses for SolarWinds NetFlow Traffic Analyzer. In terms of pricing, its license is not that expensive versus other tools such as HP."
"NetFlow Traffic Analyzer is reasonably priced."
"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."
"Licensing for SolarWinds NetFlow Traffic Analyzer is paid yearly, and there are no additional costs that you need to pay apart from the standard licensing fees because you don't need to purchase another solution to make SolarWinds NetFlow Traffic Analyzer work. Pricing for SolarWinds NetFlow Traffic Analyzer is more expensive than other solutions."
"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 pricing is really good."
"The licensing for this solution is based on the number of nodes."
"While the pricing is fair, it could be better."
