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 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 easy to create additional dashboards specific to supporting specific tasks."
"Our company has seen massive improvements in cybersecurity position for our clients."
"Technical support seems to be good."
"It is easy to deploy and easy to handle."
"Corelight is easy to use."
"The most valuable feature is the embedded IDS from Suricata."
"It's an easy way for us to get visibility in a client's environment."
"After deploying Trellix Network Detection and Response, we saw a noticeable improvement in our security operations, as threat detection and incident times were reduced by 40 to 50 percent, the security team spent significantly less time manually analyzing network traffic, and we were able to identify suspicious activity that previously went unnoticed, leading to faster containment of potential incidents and improved overall response efficiency."
"The installation phase was easy."
"Over the thirteen years of using the product, we have not experienced a single compromise in our environment. During the COVID period, we faced numerous DDoS attacks, and the tool proved highly effective in mitigating these threats."
"It's a very simple solution and a very effective product in my network."
"It is a good product to implement, especially where the existing technology fails to detect zero day attacks."
"Improved our systems and our customers' by providing better malware protection, defense against zero-day threats, and improved network security."
"It protects from signature-based attacks and signature-less attacks. The sandboxing technology, invented by FireEye, is very valuable. Our customers go for FireEye because of the sandboxing feature. When there is a threat or any malicious activity with a signature, it can be blocked by IPS. However, attacks that do not have any signatures and are very new can only be blocked by using the sandboxing feature, which is available only in FireEye. So, FireEye has both engines. It has an IPS engine and a sandbox engine, which is the best part. You can get complete network protection by using FireEye."
"The initial setup was straightforward, you can do it by yourself, you don't have to find a partner or a FireEye expert."
 

Cons

"In the next release, building a graphical user interface would be helpful."
"Corelight hasn’t added features in a long time."
"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."
"Machine learning could be a good improvement, but it's very costly."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"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 product is pricey. We'd like it to cost less. Not all customers can afford it."
"I would like to see in Trellix Network Detection and Response more explanation about some details of the threat, and I wish it had more actions that you can take to contain the host or move it somewhere else."
"Stability issues manifested in terms of throughput maximization."
"It doesn't connect with the cloud, advanced machine learning is not there."
"Improvements could be achieved through greater integration capabilities with different firewall solutions. Integrating with the dashboard itself for different firewalls so users can also pull tags into their firewall dashboard."
"A lot of false positives."
"The customer service is not that good."
"As far as future inclusions, it would be useful to display more threat intelligence, such as the actual area of the threat and the origin of the web crawling (Tor and Dark Web)."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"It's an expensive solution."
"The tool is a bit pricey."
"The user fee is not as high but the maintenance fee is expensive."
"Its price is a bit high. A small customer cannot buy it. Its licensing is on a yearly basis."
"FireEye is comparable to other products, such as HX, but seems expensive. It may cause us to look at other products in the market."
"There are some additional services that I understand the vendor provides, but our approach was to package all of the features that we were looking to use into the product."
"Pricing and licensing are reasonable compared to competitors."
"The pricing is a little high."
