Gained full visibility and streamlined threat detection through behavior-based insights and AI integration
Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth. We have fine-tuned our security policies and allowed different levels of policies to get rid of those false positives. Currently, we are getting a fairly good amount of incidents that are not false positives or benign, but actionable items. The process is streamlined. In the initial days, the operations used to get involved in a lot of benign and other activities, but now the process is streamlined. We are leveraging the auto-detection and remediation plans. The operations teams are now more involved in other business roles as well, not just looking into the logs and fetching out what's happening there. They have fixed a lot of things. Initially, they didn't have IAC code drift detection, cloud posture management, or security posture management, but they have those now. They purchased different vendors and did a merger with that. They have now Prisma Cloud that gets integrated and now they are working with Cortex Cloud. Everything that was negative has now been addressed, and the product altogether looks to be in a very better and mature shape now. Currently, it's more or less detecting the workloads with AI-based best practices. Since most organizations are consuming AI agents and other things, we are looking forward to seeing what other feature enhancements Palo Alto can support in that.

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.

Unified threat detection has improved investigations and now speeds up incident response
While Trellix XDR is a strong platform overall, there are a few areas where it could be improved. The initial setup and configuration can be complex, especially for organizations with diverse environments. Some additional advanced features also have a learning curve and may require extra training for security teams to fully utilize them. Moreover, reporting and dashboard customization could be more flexible, allowing users to create highly customized views and reports more easily. There are also areas that could optimize detection surveys. Addressing these areas would further enhance the overall experience and operational effectiveness. One additional improvement would be deeper integration with a wider range of third-party security tools and cloud platforms. While Trellix XDR integrates with many solutions, simplifying the integration management would help organizations with complex security ecosystems. I would like to see more out-of-the-box reports and executive-level dashboards that make it easier to communicate security metrics to leadership. Finally, continuous enhancement to automation and AI-driven threat prioritization would further reduce analysts' workflow and improve response effectiveness. Overall, these are areas that need refinement rather than being major concerns, as the platform still delivers strong security and operational value.

Quotes from Members

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

Pros

"We've had a significant increase in blocking with a decrease in false positives, because it's looking at how the files work, not just a list of files that it's been told to look for."
"One of the main benefits of the solution is its intelligence to correlate the events into an incident."
"The product is very good, it has caught a lot of exploits that most products would not."
"We think that this product will help us grow, as it meets our needs currently and we can grow with it over time."
"We switched because there were a lot of added features with Palo Alto that Check Point didn't have, and it was an upgrade for us."
"The dashboard is customizable."
"Monitoring is most valuable."
"The information the dashboard provides is very clear."
"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."
"It contributes to our system's robust event detection and analysis, enabling us to respond effectively to incidents."
"Trellix's technical support is helpful."
"The AI-assisted troubleshooting and threat hunting capabilities, along with the machine learning functionality, are the biggest advantages of Trellix XDR that stand out for me."
"The analytics assessment and flexibility of the platform are valuable."
"Trellix XDR is an excellent solution that is continually improving."
"Trellix XDR has impacted my organization positively as it's a security solution that protects us from threats."
"The best features of Trellix XDR are the in-depth analysis it provides."
"Trellix XDR has positively impacted my organization in a couple of major ways: The efficiency of the SOC team has increased, and incident investigation speed has improved significantly."
 

Cons

"They've been having some issues with updating their endpoint agents, and it has been quite frustrating."
"This product has not improved my organization - in fact, we are in the process of moving back to another product as a result of Cortex's horrible impact on system performance."
"Currently, if you use Palo Alto endpoint protection as the only solution it's very complicated to remove pre-existing threats."
"In the next release, I would like to see more UI improvements. Their UI is a bit basic. When we are speaking about Palo Alto Networks they are the big company, so they can improve the UI a little bit. The UI, the reports, the log system can all be improved."
"It tends to do 99.9% of things. The only thing I'd like is single sign-on authentication into their cloud platform so that my users can be properly authenticated against it."
"Cortex XDR is trickier to configure than other Palo Alto products. This is one area where we are not so satisfied."
"The tool needs to be improved in terms of integration and interface."
"The playbooks could be improved to include more functionalities or actions."
"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 believe Trellix XDR could improve better visualization of attack paths and threat relationships."
"Customer support is average, depending on who the call gets to, escalation, and how quickly they respond."
"We have left Trellix XDR. The pricing was the main factor because the features were not there and they were charging more from us."
"Price is the main area for improvement in the product."
"Technical support is crucial, especially when facing critical issues. It's rated six out of ten. Improvements are needed in the support sector, with a focus on providing expert assistance during production periods."
"The EdgeGear solution is an area that requires attention, specifically regarding AI solutions and intelligence features."
"The main area regarding Trellix XDR improvement is that setup and tuning can be complex because it requires a skilled analyst based on utilization."
"The initial setup and configuration can be complex, especially for organizations with diverse environments."
 

Pricing and Cost Advice

"The price of the solution is high for the license and in general."
"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"I don't like that they have different types of licenses."
"I am using the Community edition."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."
"Very costly product."
"It’s a single license platform."
