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.

Unified security monitoring has reduced alert fatigue and improves proactive threat hunting
I use real-time monitoring in ReliaQuest GreyMatter, which significantly improves my security posture. The unified interface helps reduce alert fatigue. I would estimate it saves around 20% in alert fatigue reduction. The automated threat hunting capabilities in ReliaQuest GreyMatter help me stay ahead of threats. The machine learning algorithm benefits my threat intelligence by providing deeper insights and predictions. I use various metrics to rate the success of the predictive threat intelligence in ReliaQuest GreyMatter.

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

Cons

"The product's pricing needs improvement. They could provide more discounts. Additionally, the dashboard and control panel could be enhanced."
"The main issue I could point out is the offline agents and the way that it is missing."
"I have seen lagging with Cortex XDR by Palo Alto Networks. There was one time when we faced a threat actor trying to gain access to our system. When our team utilized the tool, we were all on the same dashboard and we faced a lag issue at that time of around five minutes, which was quite significant."
"For working with the solution, you only really need a web browser, however, we've found that working on Chrome, for example, is horrible."
"The deployment is pretty hard."
"The solution should add unwanted malicious hash values to a block list so that whenever the action is triggered, it will automatically prevent the malicious content."
"Basically, they don't provide customer support tools just to investigate the logs."
"A potential area of improvement for Cortex XDR by Palo Alto Networks is the cost."
"Areas that have room for improvement include user interface and integration."

"I believe Trellix XDR could improve better visualization of attack paths and threat relationships."
"The initial setup and configuration can be complex, especially for organizations with diverse environments."
"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."
"Customer support is average, depending on who the call gets to, escalation, and how quickly they respond."
"Trellix XDR should get involved in AI security itself."
"The platform should enhance compatibility with all other SIEM solutions."
 

Pricing and Cost Advice

"Cortex XDR's pricing is ok."
"The pricing is a little high. It is per user per year."
"The price of the product is not very economical."
"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."
"The return on investment is from the user side because we have seen the performance of it increase the delivery time of the product if we are using too many web-based and on-premise applications. In indirect ways, we saw the return of investment in terms of performance and user satisfaction increase."
"I feel it is fairly priced."
"Very costly product."
"The price of the solution is high for the license and in general."
