Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Threat detection has improved for zero‑day attacks but alert noise and support still need work
There are many ways Trellix Network Detection and Response can be improved. Trellix Network Detection and Response needs to reduce the alert noise because even after a lot of filtering, there is still a lot of noise which needs to be tuned by the industry vertical. Trellix Network Detection and Response needs to deepen the cloud-native support with parity between on-premises and cloud deployments. Trellix Network Detection and Response needs to improve threat intelligence depth as Trellix Network Detection and Response is not known to have the best signatures or the AI-supported intelligence that competitors may have. Trellix Network Detection and Response also needs revamped documentation because we had a lot of issues trying to find the syntaxes for all the rule-making. We had to search a lot and Trellix Network Detection and Response does not really help with their documentation, as it only covers basic information. The customer service is not that good. Trellix Network Detection and Response needs accelerated customer support to reach out to the top-level heads. Most of the time we are just stuck at the ground level talking to their customer support team, and they are not able to help us because we usually need to connect with the engineering team to help us out with the specifics.

Quotes from Members

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

Pros

"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
"Before FireEye, most of the times that an incident would happen nobody would be able to find out where or why the incident occurred and that the system is compromised, FireEye is a better product because if the incident already happened I know that the breach is there and that the system is compromised so we can take appropriate action to prevent anything from happening."
"It has provided us with better malware, intrusion and incident detection."
"Very functional and good for detecting malicious traffic."
"Support is very helpful and responsive."
"Before FireEye, most of the times that an incident would happen nobody would be able to find out where or why the incident occurred and that the system is compromised. FireEye is a better product because if the incident already happened I know that the breach is there and that the system is compromised so we can take appropriate action to prevent anything from happening."
"It is a good product to implement, especially where the existing technology fails to detect zero day attacks."
"The installation phase was easy."
"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."
 

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."
"The pricing is not reasonable. The user fee is not as high but the maintenance fee is expensive."
"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."
"It would be a good idea if we could get an option to block based upon the content of an email, or the content of a file attachment."
"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."
"A lot of false positives."
"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."
"The customer service is not that good."
 

Pricing and Cost Advice

"It’s a single license platform."
"The user fee is not as high but the maintenance fee is expensive."
"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."
"Pricing and licensing are reasonable compared to competitors."
"We're partners with Cisco so we get a reasonable price. It's cheaper than Palo Alto in terms of licensing."
"Its price is a bit high. A small customer cannot buy it. Its licensing is on a yearly basis."
"The tool is a bit pricey."
"It's an expensive solution."
"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."
