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.
BiswabhanuPanda - PeerSpot reviewer
Offers in-depth investigation capabilities, integrates well and smoothly transitioned from a lower-capacity appliance to a higher one
The in-depth investigation capabilities are a major advantage. When the system flags something as malicious, it provides a packet capture of that activity within the environment. That helps my team quickly identify additional context that most other tools wouldn't offer – like source IP or base64 encoded data. We can also see DNS requests and other details that aren't readily available in solutions like Check Point or others that we've tried. The detection itself is solid, and their sandboxing is powerful. There's a learning curve – you need a strong grasp of OS-level changes, process forking, registry changes, and the potential impact of those. But with that knowledge, the level of information Trellix provides is far greater than what we've seen elsewhere. The real-time response capability of Trellix has been quite effective, although it's not very fast. The key is this solution's concept of 'preference zero.' They don't immediately act on a zero-day. For example, the solution has seen a piece of malware for the first time. It'll let it in, then do sandboxing. Maybe after four or five minutes, it identifies that specific file's DNX Secure Store as malicious. At that point, they update the static analysis engine, and it gets detected if anything else tries to download the same file. There is that initial 'preference zero' concept, like with Panda. You may not hold traffic in the network. That's standard in the industry; we don't do much about it. To address that, we also have endpoint solutions. We use SentinelOne in our environment, which helps us identify threats like Western Bureaus and others.

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 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."
"It is easy to deploy and easy to handle."
"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."
"The most valuable feature is the network security module."
"The installation phase was easy."
"Application categorization is the most valuable feature for us. Application filtering is very interesting because other products don't give you full application filtering capabilities."
"The MVX Engine seems to be very capable against threats and the way it handles APTs is impressive."
"We see ROI in the sense that we don't have to react because it stops anything from hurting the network. We can stop it before we have a bigger mess to clean up."
"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."
"Very functional and good for detecting malicious traffic."
 

Cons

"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"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."
"Cybersecurity posture has room for improvement."
"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."
"If you want to search the hashes in the environment, you need to put in IOCs one by one, making it a very hectic job."
"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."
"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."
"Certain features in Trellix Network Detection and Response, such as using AL-type commands, may initially pose a challenge for those unfamiliar with such commands. However, once users become accustomed to the system, it becomes easier to use."
"The analytics could be better. It seems heavily influenced by the McAfee and FireEye integration, and that integration still isn't seamless."
"Management of the appliance could be greatly improved."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"Its price is a bit high. A small customer cannot buy it. Its licensing is on a yearly basis."
"We're partners with Cisco so we get a reasonable price. It's cheaper than Palo Alto in terms of licensing."
"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 tool is a bit pricey."
"It's an expensive solution."
"FireEye is comparable to other products, such as HX, but seems expensive. It may cause us to look at other products in the market."
"The pricing is a little high."
"When you purchase FireEye Network Security NX, will need to purchase a megabit per second package. You must know your needs from day one."
