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

"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."
"Corelight is easy to use."
"The most valuable feature is the embedded IDS from Suricata."
"It is easy to deploy and easy to handle."
"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."
"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."
"Improved our systems and our customers' by providing better malware protection, defense against zero-day threats, and improved network security."
"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."
"Trellix NDR provides an essential defense by automatically responding to network incidents that firewalls may not catch."
"The product has helped improve our organization by being easy to use and integrate. This saves time, trouble and money."
"I also like its logging method. Its logging is very powerful and useful for forensic purposes. You can see the traffic or a specific activity or how something entered your network and where it went."
"The most valuable feature is the network security module."
 

Cons

"Corelight hasn’t added features in a long time."
"Machine learning could be a good improvement, but it's very costly."
"In the next release, building a graphical user interface would be helpful."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"The world is currently shifting to AI, but FIreEye is not following suit."
"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."
"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."
"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)."
"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."
"It doesn't connect with the cloud, advanced machine learning is not there. A known threat can be coming into the network and we would want the cloud to look up the problem. I would also like to see them develop more file replication and machine learning."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"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."
"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."
"When I compare this solution to its competitors in the market, I find that it is a little expensive."
"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 a little high."
"The pricing is fair, a little expensive, but fair. We've evaluated other products, and they're similarly priced."

The two platforms take a fundamentally different approach to NDR. Corelight is limited to use cases that require the eventual forwarding of events and parsed data logs to a security team’s SIEM or ...
What do you like most about Corelight?
It's easy to create additional dashboards specific to supporting specific tasks.
What is your experience regarding pricing and costs for Corelight?
The solution is too expensive compared to others. If you have the technical knowledge, it's good. Corelight is a very big gap between you and others if you’re new.
What do you like most about FireEye Network Security?
We wanted to cross-reference that activity with the network traffic just to be sure there was no lateral movement. With Trellix, we easily confirmed that there was no lateral network involvement an...
What is your experience regarding pricing and costs for FireEye Network Security?
While I do not handle pricing directly, it is known that there is a variety of customers with different licensing needs, which depends on the organization's size and policy.
What needs improvement with FireEye Network Security?
The Trellix solution could be improved by enhancing the Central Management Console for faster visibility, which would help in network detection response. Networking often involves complexity that c...
