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.

Beneficial AI detection, helpful support, but modern UI needed
The initial setup of the Hillstone I-Series Server Breach Detection System requires a bunch of steps starting with installing the hardware and setting it up. However, most of the setup is done by the vendor. I rate the initial setup of the Hillstone I-Series Server Breach Detection System an eight out of ten. The vendor provides free training in the software provided.

Quotes from Members

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

Pros

"Technical support seems to be good."
"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."
"The most valuable feature is the embedded IDS from Suricata."
"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."
"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."
"One or two people can maintain and support the solution. The maintenance is not difficult."
"The most valuable features of the Hillstone I-Series Server Breach Detection System are the AI detection and monitoring of common threats."
 

Cons

"In the next release, building a graphical user interface would be helpful."
"Machine learning could be a good improvement, but it's very costly."
"Corelight hasn’t added features in a long time."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"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."
"It's an expensive solution and the price could be reduced."
"The UI dashboard view needs to be improved because it is ugly. If it was more modern it would be better. Additionally, better integration with other databases would be good."
"Hillstone I-Series Server Breach Detection System can improve by having more anti-spam features that will hopefully eliminate all of the other threats."
 

Pricing and Cost Advice

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