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.

Dashboard design excels while prediction algorithms need improvement
Splunk User Behavior Analytics is still an immature product, so it still needs some R&D to be able to be mature in the market. The prediction, algorithms, and ML codes behind Splunk User Behavior Analytics need to be more tuned. The logic needs to be reviewed because it has many false positives. For Splunk User Behavior Analytics, it is not yet a mature product and we are not recommending this to mature customers for now. The machine learning algorithm in Splunk User Behavior Analytics is actually the core thing that needs to be updated because this feeds all the other functions inside it. If the ML functions are not good enough, that means the risk scoring and all other related information will not be correct.

Quotes from Members

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

Pros

"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."
"Corelight is easy to use."
"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 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."
"It is easy to deploy and easy to handle."
"Technical support seems to be good."
"The solution is extremely scalable. Our customers are regularly scaling up after installing Splunk."
"The automation is very good; the product is at the forefront of auto-remediation networking and the pricing of the solution is very reasonable."
"Our main use of this solution is threat intelligence and we are very satisfied with it, as it is exactly what we need in our situation."
"Splunk User Behavior Analytics is known for its advanced analytics and data correlation capabilities, which help in detecting patterns, anomalies, and security threats."
"The solution is definitely scalable."
"The most valuable features are the indexing and powerful search features."
"Splunk User Behavior Analytics is a one hundred percent stable solution."
"This intelligent user behavior analytics package is easy to configure and use while remaining feature filled."
 

Cons

"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."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"In the next release, building a graphical user interface would be helpful."
"Corelight hasn’t added features in a long time."
"Machine learning could be a good improvement, but it's very costly."
"It's an expensive solution and the price could be reduced."
"The solution is much more expensive than relative competitors like ArcSight or LogRhythm. It makes it hard to sell to customers sometimes."
"UBA is a separate tool and it should be a part of the Splunk base itself so that we can download it."
"I would like to see a better tracking intelligence module with lower costs fully integrated with a user behavior analytics module."
"If the price was lowered and the setup process was less complex, I would consider rating it higher."
"We want to have an automated system for bot hunting that enables us to detect anomalies predictively based on historical data. It would be helpful if Splunk included process mining as an alternative option. We have a threat workflow, but it would be useful if we could supplement that with some process mining capabilities over time."
"One thing I would say is that they should continue to expand it on more devices."
"I'm not aware of any lacking features."
"The price of Splunk UBA is too high."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"Pricing varies based on the packages you choose and the volume of your usage."
"There are additional costs associated with the integrator."
"I am not aware of the price, but it is expensive."
"The licensing costs is around 10,000 dollars."
"I hope we can increase the free license to be more than 5 gig a day. This would help people who want to introduce a POC or a demo license for the solution."
"My biggest complaint is the way they do pricing... You can never know the pricing for next year. Every single time you adjust to something new, the price goes up. It's impossible to truly budget for it. It goes up constantly."
