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

"Corelight is easy to use."
"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."
"It is easy to deploy and easy to handle."
"The most valuable feature is the embedded IDS from Suricata."
"The most valuable feature is MVX, which tests all of the files that have been received in an email."
"The most valuable feature is the network security module."
"The features that I find most valuable are the MIR (Mandiant Incident Response) for checks on our inbound security."
"The sandbox feature of FireEye Network Security is very good. The operating system itself has many features and it supports our design."
"Very functional and good for detecting malicious traffic."
"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."
"The server appliance is good."
"Improved our systems and our customers' by providing better malware protection, defense against zero-day threats, and improved network security."
 

Cons

"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."
"Machine learning could be a good improvement, but it's very costly."
"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 analytics could be better. It seems heavily influenced by the McAfee and FireEye integration, and that integration still isn't seamless."
"The product's integration capabilities are an area of concern where improvements are required."
"The initial setup was complex because of the nature of our environment. When it comes to the type of applications and functions which we were looking at in terms of identifying malicious threats, there would be some level of complexity, if we were doing it right."
"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."
"There is a lot of room for Improvement in the offering, from cost to functionality. It is pretty straightforward to implement which is an advantage. However, it falls short in pricing, detection capabilities, and, most importantly, reporting and policy management."
"Based on what we deployed, they should emphasize the application filtering and the web center. We need to look deeper into the SSM inspection. If we get the full solution with that module, we don't need to get the SSM database from another supplier."
"Cybersecurity posture has room for improvement."
"A better depth of view, being able to see deeper into the management process, is what I'd like to see."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"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."
"It's an expensive solution."
"The pricing is fair, a little expensive, but fair. We've evaluated other products, and they're similarly priced."
"The tool is a bit pricey."
"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."
"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."
"When you purchase FireEye Network Security NX, will need to purchase a megabit per second package. You must know your needs from day one."
