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.

Provides contextual alerts and risk ratings on findings
It's kind of difficult to quantify areas for improvement. In the larger picture, one challenge is that the NDR space is very crowded today. I can mention half a dozen names just off the top of my head. There are at least 12 to 20 different players. All of them are well-known brand names, and it's difficult to compare them. They all claim to be giving you the same network difference capability: catching malware, dealing with all the minor taxonomy of attack, all that. Still, it's very difficult to compare them side by side because they all do things a little differently, and they all have different presentations and output. We haven't deployed it, so I can't give you what we felt about it exactly. But in the larger perspective, the critical feature is really giving a clear separation between a low, high, and medium criticality. You need a rating that is really true to the actual attack. There's one other capability we are evaluating them for, and it's for custom alerts detection. A lot of these products are trying to profile the threats that are already out there in the industry. They're very well known and published. Today, there are targeted acts being played against organizations, so you have to be sensitive to how your firewalls, protocols, and your HTTP are all operating. You might have some fine-tuned threats that are targeting you, and you should be able to build custom defenses. They should have some openness in terms of how you specify your threats. You get a standard library of threats. On top of it, every organization builds its own.

Quotes from Members

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

Pros

"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."
"Corelight is easy to use."
"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 is easy to deploy and easy to handle."
"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."
"The most valuable feature is the embedded IDS from Suricata."
"They can provide you very contextual alerts on if something bad is happening—coming into your network or going out of your network. As part of that, they gather a lot of threat intelligence and map your connections against that. The larger benefit is that they give you a risk rating on their findings."
 

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."
"It's an expensive solution and the price could be reduced."
"In the next release, building a graphical user interface would be helpful."
"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."
"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."
"My challenge is actually comparing offerings from different vendors across a threat spectrum that is very large. We are talking about millions of threats. How are you confident that Blue Hexagon is catching all one million of them and Palo Alto is doing the same thing? They all have their strengths. Within that, Blue Hexagon might cover 990,000 of them. Palo Alto might cover another 990,000. It's a bit difficult to compare them and say, "Oh, are they catching the same 990,000?" I don't know."
"My challenge is actually comparing offerings from different vendors across a threat spectrum that is very large."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"It's difficult to state the setup cost. All the NDRs range anywhere between $500,000, plus or minus, to $2 million. There's a spread of pricing here, depending on who you are talking to. Obviously the major brand names want more money. They typically bundle it with their other offerings. With Cisco, for example, you don't just buy an NDR. So, typically it gets rolled into the cost."
