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.

Cons

"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."

"Machine learning could be a good improvement, but it's very costly."

"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."

"Corelight hasn’t added features in a long time."

More Corelight Open NDR cons

"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."

"This solution would benefit from having more security-based communications between the actual devices and the software itself."

"The plotting of the device on the map is not appropriate."

"It's not a cheap product, so the pricing could be improved."

"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."

"SolarWinds' technical support is ok, but it could be faster and more knowledgeable."

"The problem is that SolarWinds is trying to bolt in too much and that can leave bugs, which you have to then sort out, leaving the product unstable."

"It does not flow. It cannot do our metric performance monitoring. So it is very limited. They can do it but in a very limited fashion. It is only good for SNMP-based alerts."

More SolarWinds NetFlow Traffic Analyzer cons

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."

"We have licenses for SolarWinds NetFlow Traffic Analyzer. In terms of pricing, its license is not that expensive versus other tools such as HP."

"The price of this solution is exceptional."

"NetFlow Traffic Analyzer is reasonably priced."

"For our environment, we pay approximately $25,000 USD yearly."

"The licensing for this solution is based on the number of nodes."

"The pricing is really good."

"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."

"The pricing is reasonable."
