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.

Centralized visibility has improved SOC investigations and supports faster, more accurate incident response
I think ReliaQuest GreyMatter could be improved further in a few areas. First, I want to see more flexibility in dashboard customization so analysts can configure views based on their roles and investigation requirements. Second, improving alert correlation accuracy and reducing overall false positive rates would help analysts focus on genuine possible threats rather than spending time validating repetitive low-priority alerts or false positives. Third, more detailed investigation timelines, better reporting capabilities, and simpler investigation integration configuration would make the platform more effective. I suggest continuously improving automation workflows to reduce repetitive manual tasks while allowing analysts to maintain control over critical response actions. Overall, I think these enhancements can make the platform more user-friendly and improve the efficiency of SOC operations. One additional improvement would be enhancing the investigation experience by providing more detailed context directly within the alert. For example, having a clear incident timeline, related alerts, historical activity, and threat intelligence information available in one place would make investigations easier. I believe these improvements would make day-to-day SOC operations smoother and allow analysts to focus more on proactive threat hunting and other complex investigations.

Quotes from Members

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

Pros

"From the Palo Alto side, whatever they buy, they integrate that really well into their integration suite, and that makes a massive difference."
"The anti-exploit is impenetrable."
"What I like about Cortex XDR by Palo Alto Networks is that it is a comprehensive solution that contains everything the organization may need when using endpoints."
"The best feature of Cortex XDR by Palo Alto Networks is that it collects logs from different sections such as the endpoint, the network, and the cloud, making it easy to investigate alerts, collect some of the investigation packages related to the infected machines, and provide live response."
"I don't have to do much monitoring with it; I don't have to have anybody manually looking at this, it gives us reports, and it lets us know if something needs to be addressed, and we can easily address it."
"After deploying Traps, we saw the performance of the network improve by 65 to 70 percent."
"The initial setup is pretty easy."
"Palo Alto is the core of the security infrastructure in the environment."
"ReliaQuest GreyMatter saves around 60% of time or resources."
"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."
"One of the best features that ReliaQuest GreyMatter offers is the ability to bring together security tools and data that support threat investigation, detection, and response."
 

Cons

"The GUI could be improved. It's a little bit cumbersome. It could be more user-friendly."
"The technical support is not very good. I find the process difficult."
"The installation should be easier and the Palo Alto pre-sales and sales teams should have more information on the product because they don't know what they are selling."
"Cortex XDR by Palo Alto Networks can improve mobile integration to allow access to the console."
"The price could be a little lower."
"The dashboard could use some significant improvement, just making it more useful with more information. It has a limited amount of information right now. It is customizable, but I'd love to see a better out-of-box dashboard."
"For working with the solution, you only really need a web browser, however, we've found that working on Chrome, for example, is horrible."
"In an upcoming release, the solution could improve by proving hard disk encryption. If it could support this it would be a complete solution."
"Areas that have room for improvement include user interface and integration."
"ReliaQuest GreyMatter is stable to a certain extent, but there is still some room for improvement."
