Dan Jeske - PeerSpot reviewer
An open-source solution that gave us insight into our clients' network traffic flow
We use the solution for packet capture sampling. We offer it as part of our managed service. It's so we can identify east-west traffic on a customer's network Corelight is low-cost and made on open-source, and the code is Zeek. It's an easy way for us to get visibility in a client's environment.…
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

"The most valuable feature is the embedded IDS from Suricata."
"It's easy to create additional dashboards specific to supporting specific tasks."
"Corelight is easy to use."
"It's an easy way for us to get visibility in a client's environment."
"It is easy to deploy and easy to handle."
"The MVX Engine seems to be very capable against threats and the way it handles APTs is impressive."
"The most valuable feature is MVX, which tests all of the files that have been received in an email."
"The product has helped improve our organization by being easy to use and integrate. This saves time, trouble and money."
"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."
"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."
"Very functional and good for detecting malicious traffic."
"Support is very helpful and responsive."
"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."
 

Cons

"Machine learning could be a good improvement, but it's very costly."
"In the next release, building a graphical user interface would be helpful."
"Corelight hasn’t added features in a long time."
"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."
"It is very expensive, the price could be better."
"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."
"Technical support could be improved."
"The Trellix solution could be improved by enhancing the Central Management Console for faster visibility, which would help in network detection response."
"Management of the appliance could be greatly improved."
"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."
"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."
"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."
"Pricing and licensing are reasonable compared to competitors."
"When you purchase FireEye Network Security NX, will need to purchase a megabit per second package. You must know your needs from day one."
"We're partners with Cisco so we get a reasonable price. It's cheaper than Palo Alto in terms of licensing."
"The user fee is not as high but the maintenance fee is expensive."
"The pricing is a little high."
"The tool is a bit pricey."
"The pricing is fair, a little expensive, but fair. We've evaluated other products, and they're similarly priced."
"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."
