Network visibility has transformed how we detect nation state threats and protect critical industry
Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale. However, I think with a lot of the artificial intelligence that they are building in, it is getting a lot easier to query in the platform. I would definitely encourage them to continue down that path where anybody can hop into the platform and start running queries, whether it is a simple instruction like I want this, and an artificial intelligence process can actually build the query and do it. I think that would be super powerful. Cyber skill sets are in high demand, and there is a huge backlog in cyber talent. We cannot fill all the positions we need. The easier we can make these cyber systems for people to pick up and be effective on, I think is really key. Explainability of data is hyper important. In the past few artificial intelligence related updates we have gotten from Corelight, that has been one of the first questions our team has asked every time or that I have asked: show me what the model is doing, show me how it came to this analysis. Within Investigator platform, they are able to walk through and see exactly what data the artificial intelligence pulled from where and why it did what it did as far as making its suggestions. They have definitely built their system with artificial intelligence in mind up front, and having that openness as one of the key features of any of their artificial intelligence and machine learning processes in the platform is important. The issue with black boxes is obviously hallucinations from artificial intelligence and just not being able to trace to ground truth. When we are talking about these cyber incidents and being able to do forensics, you need to be able to pinpoint and tie everything together, and black boxes really obscure that and prevent you from doing so. Corelight has done a really good job of making sure that everything is explainable and everything is mapped when it comes to leveraging any of their artificial intelligence features.

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

"Corelight is easy to use."
"Our company has seen massive improvements in cybersecurity position for our clients."
"It's an easy way for us to get visibility in a client's environment."
"The most valuable feature is the embedded IDS from Suricata."
"Corelight makes much easier the remediation of cyber attacks; instead of facing a chaotic amount of logs, Corelight provides correlated metrics that allow pivoting to find, in seconds, all the data related to an alert, detection, or asset."
"It's easy to create additional dashboards specific to supporting specific tasks."
"Corelight Open NDR has had a positive impact on my company, providing visibility as the Suricata engine can scan huge volumes of traffic, including north-south and east-west, revealing signatures and exposures I was not expecting and enabling me to catch them with Suricata alerts."
"It is easy to deploy and easy to handle."
"We were previously using Zabbix, we also looked at alternative products such as Nagios, but SolarWinds was actually decided on only because it's got a lovely graphical interface, it's easy to use, has powerful reporting features, and excellent support."
"The program is scalable enough for our usage."
"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."
"For stability, I would give SolarWinds NetFlow Traffic Analyzer a rating of ten out of ten."
"The monitoring is perfect, showing you the details for the utilization of resources and network bandwidth."
"It provides proactive monitoring, rather than waiting for applications to go down due to heavy bandwidth or latency."
"The support is excellent."
"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."
 

Cons

"Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"Machine learning could be a good improvement, but it's very costly."
"It's an expensive solution and the price could be reduced."
"In the next release, building a graphical user interface would be helpful."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"Corelight hasn’t added features in a long time."
"The solution needs better log management and log coordination with tools."
"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."
"An area for improvement in SolarWinds NetFlow Traffic Analyzer is application visibility because some applications aren't being recognized correctly. You can see applications such as Facebook and YouTube, but SolarWinds NetFlow Traffic Analyzer needs to have more visibility into more applications. Currently, SolarWinds fails to detect more powerful applications, such as Zoom and Teams. If SolarWinds NetFlow Traffic Analyzer can recognize every application and be able to report on each in terms of bandwidth, then that would be good. This is what I'd like to see in the next release of the solution."
"It's not a cheap product, so the pricing could be improved."
"There is room for improvement when it comes to the traffic generated by the analyzer and the analysis of that traffic."
"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."
"The plotting of the device on the map is not appropriate."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"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 solution's licensing is high-priced."
"We have licenses for SolarWinds NetFlow Traffic Analyzer. In terms of pricing, its license is not that expensive versus other tools such as HP."
"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."
"NetFlow Traffic Analyzer is reasonably priced."
"While the pricing is fair, it could be better."
"The pricing is reasonable."
"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."
