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.

Continuous network insight has improved early threat detection and streamlined investigations
Overall, we have a positive experience with Trellix Network Detection and Response, but like any enterprise security solution, there are areas where it can continue to improve. One area would be user interface and dashboard customization. While the platform provides a lot of valuable information, new users can sometimes face a learning curve when navigating and investigating and creating customized views. More intuitive dashboards would simplify workflows and help analysts access critical information even faster. Another area for improvement is reporting and analytics. The existing reporting capabilities are useful, but more flexibility and customizable reporting options would make it easier to generate executive-level summaries, compliance reports, and operational metrics for different audiences.

Quotes from Members

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

Pros

"Corelight is easy to use."
"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."
"Our company has seen massive improvements in cybersecurity position for our clients."
"Technical support seems to be good."
"The most valuable feature is the embedded IDS from Suricata."
"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."
"Trellix Network Detection and Response offers excellent diversity and support for different capabilities because it is built and composed of different services."
"The solution can scale."
"FireEye has placed us in the position to proactively counter malicious threats; we now don’t have to take a user offline in order to rebuild their PC following an attack."
"Application categorization is the most valuable feature for us."
"The features that I find most valuable are the MIR (Mandiant Incident Response) for checks on our inbound security."
"The biggest impact Trellix Network Detection and Response has had on our organization is improved visibility across our environment and better confidence during investigations, as security analysts can understand suspicious behavior more clearly instead of depending solely on isolated alerts."
"Both for our clients and for ourselves, ROI was almost 200% more than we expected."
"It is stable and quite protective. It has a lot of features to scan a lot of malicious things and vulnerabilities."
 

Cons

"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"It's an expensive solution and the price could be reduced."
"Machine learning could be a good improvement, but it's very costly."
"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."
"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."
"Corelight hasn’t added features in a long time."
"Technical packaging could be improved."
"Cybersecurity posture has room for improvement."
"It is very expensive, the price could be better."
"The problem with FireEye is that they don't allow VM or sandbox customization. The user doesn't have control of the VMs that are inside the box. It comes from the vendor as-is. Some users like to have control of it. Like what type of Windows and what type of applications and they have zero control over this."
"The negative aspect is support."
"It would be a good idea if we could get an option to block based upon the content of an email, or the content of a file attachment."
"The customer service is not that good."
"Improvement-wise, the initial setup, fine-tuning, and learning can take effort."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"When I compare this solution to its competitors in the market, I find that it is a little expensive."
"The pricing is a little high."
"It's an expensive solution."
"Pricing and licensing are reasonable compared to competitors."
"The user fee is not as high but the maintenance fee is expensive."
"We're partners with Cisco so we get a reasonable price. It's cheaper than Palo Alto in terms of licensing."
"When you purchase FireEye Network Security NX, will need to purchase a megabit per second package. You must know your needs from day one."
"The pricing is fair, a little expensive, but fair. We've evaluated other products, and they're similarly priced."
