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

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

Pros

"The positive impacts I see from Cortex XDR by Palo Alto Networks include a complete 360-degree view of our security posture altogether, being a uniform platform where we are ingesting logs from multiple resources."
"The live terminal is probably the best thing ever. It gives you the access to get straight onto any machine."
"Cortex XDR by Palo Alto Networks has helped lighten the load of our security analysts because it was the major tool that we were using and the one we utilized most."
"The tool is easy to use."
"Overall, it's a great platform; it integrates very well with other solutions from Palo Alto and also with our vendors, the ease of use is excellent, I love the root cause analysis from Cortex, which is amazing, and in a few clicks you can have the full root cause."
"It is easy to use."
"Implementing Cortex XDR by Palo Alto Networks has had a significant impact on my security analyst workload because it becomes much easier."
"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."
"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."
"Trellix's technical support is helpful."
"The analytics assessment and flexibility of the platform are valuable."
"Trellix XDR has impacted my organization positively because time was definitely saved because of the automated response, and the positive impact was definitely there in terms of both time saved and people being cut down from the team to have a more efficient and cost-saving team."
"Since implementing Trellix XDR, we have seen improvement in our threat detection and incident response capability."
"Trellix XDR is an excellent solution that is continually improving."
"Since implementing Trellix XDR, I have noticed positive impacts on my organization."
"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."
"It contributes to our system's robust event detection and analysis, enabling us to respond effectively to incidents."
 

Cons

"It would be good to have a better way to search for a file within the UI."
"There are some third-party solutions that are difficult to integrate with, which is something that can be improved."
"I would like to see improvement in the tool's user interface, particularly in the area of managing alerts and providing more reporting capabilities."
"They have the worst support, as a company, that I have ever worked with, as they are difficult to get a hold of and keep on the phone. They don't know what they are talking about when you get them on the phone. They don't like to respond to messages when you send them to them. They like to "research problems" for weeks on end, then pass you off to somebody else."
"They are charging for Network Traffic Analyzer (NTA) services, so if the per GB data could be provided at a certain level free of cost or at the same cost which the customer is taking for the entire bundle, that would be better."
"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."
"I would like to see some additional features related to email protection included."
"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."
"Areas that have room for improvement include user interface and integration."
"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 platform should enhance compatibility with all other SIEM solutions."
"Another reason is that their support sometimes is poor. For example, I had experience when my ticket was opened for a few months, and I pinged them every week, and they haven't responded to me."
"We have left Trellix XDR. The pricing was the main factor because the features were not there and they were charging more from us."
"Trellix XDR should get involved in AI security itself."
"Price is the main area for improvement in the product."
"The initial setup and configuration can be complex, especially for organizations with diverse environments."
 

Pricing and Cost Advice

"This is an expensive solution."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"The tool's price is moderate."
"The pricing is okay, although direct support can be expensive."
"It's about $55 per license on a yearly basis."
