Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Continuous network insight has improved early threat detection and streamlined investigations
Overall, we have a positive experience with Trellix Network Detection and Response, but like any enterprise security solution, there are areas where it can continue to improve. One area would be user interface and dashboard customization. While the platform provides a lot of valuable information, new users can sometimes face a learning curve when navigating and investigating and creating customized views. More intuitive dashboards would simplify workflows and help analysts access critical information even faster. Another area for improvement is reporting and analytics. The existing reporting capabilities are useful, but more flexibility and customizable reporting options would make it easier to generate executive-level summaries, compliance reports, and operational metrics for different audiences.

Quotes from Members

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

Pros

"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"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, and if you have these types of tools, your organization would benefit greatly."
"Trellix Network Detection and Response has positively impacted my organization by significantly reducing the time to detect as we also were experimenting with the automation systems."
"Trellix Network Detection and Response helps increase response to attacks. One benefit is increased visibility and simplicity in maintaining it. AI analyzes and relates data based on past performance over the last five days."
"The solution has allowed for growth and improvement in our information security and security operations teams."
"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."
"FireEye has placed us in the position to proactively counter malicious threats; we now don’t have to take a user offline in order to rebuild their PC following an attack."
"The sandbox feature of FireEye Network Security is very good. The operating system itself has many features and it supports our design."
"The most valuable feature is the view into the application."
 

Cons

"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
"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."
"The pricing is not reasonable. The user fee is not as high but the maintenance fee is expensive."
"Technical packaging could be improved."
"I think the UI of Trellix Network Detection and Response can be improved for a first-time user."
"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."
"Improvement-wise, the initial setup, fine-tuning, and learning can take effort."
"Stability is fine as long as we don't go deeper into the system. Once we go deeper into the SSM, inspection, and decryption, we get some issues."
"The support is somewhat lacking with long response times."
 

Pricing and Cost Advice

"It’s a single license platform."
"It's an expensive solution."
"Pricing and licensing are reasonable compared to competitors."
"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 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."
"Its price is a bit high. A small customer cannot buy it. Its licensing is on a yearly basis."
"The pricing is a little high."
"The tool is a bit pricey."
