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.

There is always room for improvement. I am not giving it a perfect score because I am sure there is something that could be enhanced.Having some sort of certification or training, along with more periodic webinars might be helpful. Having a larger support network would be beneficial. Nobody I know has heard of Lumu, so they are in the same space as Darktrace or CrowdStrike, but people give blank stares. As the community grows for Lumu then that will improve, but that is not really a criticism of Lumu, they simply have not been around that long.

Quotes from Members

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

Pros

"The most valuable feature is the embedded IDS from Suricata."
"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 easy to create additional dashboards specific to supporting specific tasks."
"Technical support seems to be good."
"It is easy to deploy and easy to handle."
"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."
"The context provided by the tool is very complete, it includes the miter matrix, playbooks, links, hashes, and much more."
"With this solution, you don’t need to invest in expensive cybersecurity software because you can operate within the product easily."
"Lumu has allowed us to operate cybersecurity in a better way, with a manageable number of incidents that contain all the context including the Mitre matrix and much more, while providing visibility across on-premise, cloud, remote environments, and IoT such as IP cameras, with automatic mitigation that lets our team focus only on incidents that require our full attention."
"Most of it is automated, so I do not have to watch it to get alerts."
"You can access external links, playbooks, MITRE Matrix, and a lot of information."
"It's been helpful for overall extended network visibility."
"I like Lumu's simple user interface. When we deployed it, we got full access, allowing us to identify IP addresses on the network and connect machine names to users. It helped us identify and block threats via the firewall. I also appreciate the chat support and ticket closure process. We're currently reviewing network detection solutions, and my recommendations include Lumu, Sentinel, and a few others. Regarding functionality and user-friendliness, I would recommend Lumu over the others."
"The automated response to incidents works effectively out of the box, and the number of interfaces and platforms it can work with is impressive."
 

Cons

"Machine learning could be a good improvement, but it's very costly."
"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."
"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."
"Corelight hasn’t added features in a long time."
"In the next release, building a graphical user interface would be helpful."
"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."
"I am happy with the current features. However, one important one is to improve the reports."
"Having a larger support network would be beneficial. Nobody I know has heard of Lumu, so they are in the same space as Darktrace or CrowdStrike, but people give blank stares."
"Nothing so far needs to be improved."
"The integration with different vendors and endpoints could be improved."
"It would be good if we could access the physical logs."
"The reports need improvement."
"I am happy with the current features. However, one important one is to improve the reports."
"Lumu's ability to discover threats is an area of concern where improvements are needed."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"Compared to Lumu, other solutions are more expensive. SentinelOne was a bit cheaper, and another provider's price structure is unclear, but Lumu fit our budget nicely. SentinelOne's cost depends on the number of devices, and it might be similar to Lumu's, depending on deployment."
"It is the cheapest solution we found."
"The tool is available at a good price. The tool offers a good and competitive price for customers."
