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.

Quotes from Members

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

Pros

"It is easy to deploy and easy to handle."
"It's easy to create additional dashboards specific to supporting specific tasks."
"Our company has seen massive improvements in cybersecurity position for our clients."
"Technical support seems to be good."
"It's an easy way for us to get visibility in a client's environment."
"Corelight is easy to use."
"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."
"The most valuable feature is the embedded IDS from Suricata."
"The feature that I have found the most useful is the decode of packets. It gives us a variety of information that helps us in figuring out what to look at. The networks are getting really complex, and without the information that we get from Iris Session Analyzer, we couldn't do our job. Its graphical user interface is also very easy to use and intuitive."
"A great feature is the memory utilization graph."
"We have a good relationship with NETSCOUT, and it's reflected in the communication and the service that we see from them."
 

Cons

"It's an expensive solution and the price could be reduced."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"Corelight hasn’t added features in a long time."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"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."
"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."
"Machine learning could be a good improvement, but it's very costly."
"They can increase flexibility in the search engine. Basically, I go with the information I have at the time. If I could just type in the parameter that I want to search for and its value, it might be easier than having to do the groundwork upfront before I can get my traces."
"Sometimes the network analyzer will show that a server is down when it's actually working."
"They can increase flexibility in the search engine. Basically, I go with the information I have at the time."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"I don't know what the cost to buy the solution was, but I doubt if it's a significant part of the budget as far as the maintenance and support are concerned."
