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

"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."

"It's an easy way for us to get visibility in a client's environment."

"Our company has seen massive improvements in cybersecurity position for our clients."

"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."

"Corelight is easy to use."

"The most valuable feature is the embedded IDS from Suricata."

More Corelight Open NDR pros

"The most valuable feature is the network security module."

"The server appliance is good."

"Trellix Network Detection and Response is a great tool that integrates with a lot of security tools such as Palo Alto, which is a good firewall, and if you have these types of tools, your organization would benefit greatly."

"The installation phase was easy."

"The simplified Alert Dashboard is straightforward to navigate."

"It's a very simple solution and a very effective product in my network."

"The solution has allowed for growth and improvement in our information security and security operations teams."

More Trellix Network Detection and Response pros

Cons

"It's an expensive solution and the price could be reduced."

"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."

"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."

"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."

"There is a lot of room for Improvement in the offering, from cost to functionality. It is pretty straightforward to implement which is an advantage. However, it falls short in pricing, detection capabilities, and, most importantly, reporting and policy management."

"Its documentation can be improved. The main problem that I see with FireEye is the documentation. We are an official distributor and partner of FireEye, and we have access to complete documentation about how to configure or implement this technology, but for customers, very limited documentation is available openly. This is the area in which FireEye should evolve. All documents should be easily available for everyone."

"Cybersecurity posture has room for improvement."

"I heard that FireEye recently was hacked, and a lot of things were revealed. We would like FireEye to be more secure as an organization. FireEye has to be more protective because it is one of the most critical devices that we are using in our environment. They have a concept called SSL decryption, but that is only the packet address. We would like FireEye to also do a lot of decryption inside the packet. Currently, FireEye only does encryption and decryption of the header, but we would like them to do encryption and decryption of the entire packet."

"Technical support needs improvement as sometimes engineers are not available promptly, especially during high-severity incidents."

"Improvement-wise, the initial setup, fine-tuning, and learning can take effort."

"The negative aspect is support."

"Technical packaging could be improved."

More Trellix Network Detection and Response cons

Pricing and Cost Advice

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

"Because of what the FireEye product does, it has significantly decreased our mean time in being able to identify and detect malicious threats. The company that I work with is a very mature organization, and we have seen the meantime to analysis decrease by at least tenfold."

"We're partners with Cisco so we get a reasonable price. It's cheaper than Palo Alto in terms of licensing."

"Its price is a bit high. A small customer cannot buy it. Its licensing is on a yearly basis."

"The user fee is not as high but the maintenance fee is expensive."

"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 tool is a bit pricey."

"Pricing and licensing are reasonable compared to competitors."

"The pricing is fair, a little expensive, but fair. We've evaluated other products, and they're similarly priced."
