User friendly, cloud scalability, with surpassed return on investment goals
I found that it has a good GUI and user-friendly administration They need to have some automation models embedded in them. If you integrate that, that would be a complete package. I have been using Nagios Network Analyzer for the past five years. Nagios Network Analyzer is very stable. They…
Raja Xabi - PeerSpot reviewer
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."
"The network monitoring feature, especially, stands out to me."
"It is highly customizable and can be integrated well with third-party software."
"The initial setup is easy."
"Its initial setup process is straightforward."
"I have found that it has a good GUI and user-friendly administration."
"Network tracking is the most valuable feature of Network Analyzer."
"The tool's UI is user-friendly, and pricing is affordable. It is very easy to deploy and learn."
"What I like the most is the bandwidth assessment."
"I rate the support in SolarWinds NetFlow Traffic Analyzer as 10 out of 10 because whenever I open a tech ticket, they respond instantly, and their engineer is well-equipped to resolve the issues."
"The solution helps manage networks."
"It doesn't cost too much."
"The program is scalable enough for our usage."
"They have instructional videos and other information available on the site to assist you with learning it."
"NTA's most valuable feature is traffic analysis and visibility."
"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."
 

Cons

"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."
"The bandwidth for its front-end version needs enhancement."
"They need to have some automation models embedded in them."
"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."
"The graphics and reports can be a little bit better."
"I think the reports can be improved. They're adopted."
"There is room for improvement on the setup side."
"An area for improvement in SolarWinds NetFlow Traffic Analyzer is the dashboarding. The user interface also has room for improvement because it's currently clunky."
"The solution should improve its automation feature. It's quite limited compared to other products."
"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."
"This solution does not do a very good job when I am trying to look deeper into my internal network, in particular with respect to individual ports."
"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."
"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."
"This solution would benefit from having more security-based communications between the actual devices and the software itself."
 

Pricing and Cost Advice

"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 solution is cost-efficient."
"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 reasonable."
"While the pricing is fair, it could be better."
"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."
"The solution's licensing is high-priced."
"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."
"The pricing is really good."
"The price of this solution is exceptional."
