An expensive solution to monitor internet traffic with multiple dashboards
The huge library especially the open source link, makes it the main engine for Corelight with some enhancements in the commercial version. It has a very powerful level, such as signature-based attacks or behavioral attacks, with enhancements in the design. It is very flexible for intelligent implementations like IPs, especially between big companies and banks. Corelight is easy to understand and monitor what is going on behind the team. The solution is already integrated with other systems like Suricata, Elastic, and Microsoft tools. It's very easy to integrate signature-based or behavior-based engines. You can use Elastic for the dashboards to get it from Corelight, along with all the benefits and expandability.

Has improved threat detection workflows and supports seamless customer monitoring
The best features Trellix Network Detection and Response offers include very good threat detection, and I believe that it is one of the best XDR tools. For example, ePO and XDR components are very comfortable and similar to many other tools for this type of monitoring, and I have received very good feedback for this tool. What makes Trellix Network Detection and Response stand out for me compared to other tools is the way you can detect threats. It is very easy and comfortable to use, and the detection shows clearly on the screen, which is very easy to understand. Regarding the features, I think that the integration with other platforms is very comfortable with the customer because we can integrate it with any switch or firewall, and it is comfortable to add this tool. Trellix Network Detection and Response has positively impacted my organization as I have improved my knowledge about detection and response. I have already used some other tools such as CrowdStrike and Umbrella, but Trellix is one of the best that I have tested. I believe that for my organization, Trellix has helped a lot with detection and supported our customers effectively. 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. If you have these types of tools, your organization would benefit greatly.

Quotes from Members

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

Pros

"It is easy to deploy and easy to handle."
"It's easy to create additional dashboards specific to supporting specific tasks."
"It's an easy way for us to get visibility in a client's environment."
"The most valuable feature is the embedded IDS from Suricata."
"Corelight is easy to use."
"If we are receiving spam emails, or other types of malicious email coming from a particular email ID, then we are able to block them using this solution."
"The most valuable feature of the solution stems from how it allows users to do the investigation part. Another important part of the product that is valuable is associated with how it gives information to users in the form of a storyline."
"The sandbox feature of FireEye Network Security is very good. The operating system itself has many features and it supports our design."
"Trellix NDR provides an essential defense by automatically responding to network incidents that firewalls may not catch."
"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 most valuable feature is MVX, which tests all of the files that have been received in an email."
"Initially, we didn't have much visibility around what is occurring at our applications lower level. For instance, if we are exposed to any malicious attacks or SQL injections. But now we've integrated FireEye with Splunk, so now we get lots of triggers based on policy content associated with FireEye. The solution has allowed for growth and improvement in our information security and security operations teams."
"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."
 

Cons

"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."
"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."
"Corelight hasn’t added features in a long time."
"They can maybe consider supporting some compliance standards. When we are configuring rules and policies, it can guide whether they are compliant with a particular compliance authority. In addition, if I have configured some rules that have not been used, it should give a report saying that these rules have not been used in the last three months or six months so that I disable or delete those rules."
"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."
"We'd like the potential for better scaling."
"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."
"FireEye Network Security should have better integration with other vendors' firewalls or proxies, such as Palo Alto and Fortinet. Files that are being submitted should happen through the API or automatically."
"I would love to see better reporting. Because you can't export some of the reports in proper formats, it is hard to extract the data from reports."
"Stability issues manifested in terms of throughput maximization."
"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."
 

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."
"It's an expensive solution."
"The pricing is a little high."
"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."
"The pricing is fair, a little expensive, but fair. We've evaluated other products, and they're similarly priced."
"Pricing and licensing are reasonable compared to competitors."
"The user fee is not as high but the maintenance fee is expensive."
"The tool is a bit pricey."
