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.

Improved threat detection has reduced incidents and has automated investigations with AI
There are multiple features of ReliaQuest GreyMatter which I love personally. The agentic AI, which helps in autonomous investigation and containment, is multiplying the speed of the task to be done. Features such as managed service integration and MDR with human expertise when needed are some major features which I love about 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 product's initial setup phase is very easy."
"In one single alert, we are getting the network telemetry, endpoint telemetry, email security telemetry, and proxy telemetry all in one single ticket, making it very easy."
"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."
"It can automatically correlate events and logs, which is very helpful for an IT administrator. It can correlate different kinds of malware activities over a network, agent, or host system. You do not need to do it manually. It is a good feature. It is also a user-friendly solution. We have deployed it on the cloud because our space does not provide any flexibility for on-premises deployment, but Palo Alto has added some flexibility to install it on-premises. It must be like the same Cortex XDR agent for all the VPN services, web filtering services, and everything else."
"This software helps us understand any issues that may arise when someone is not at work."
"The protection offered by this product is good, as is the endpoint reporting."
"Cortex XDR is stable, offering high quality and reliable performance."
"Its ability to react to cyber data attacks is awesome."
"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."
"ReliaQuest GreyMatter saves around 60% of time or resources."
"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."
"Trellix XDR is an excellent solution that is continually improving."
"Since implementing Trellix XDR, we have seen improvement in our threat detection and incident response capability."
"It contributes to our system's robust event detection and analysis, enabling us to respond effectively to incidents."
"Since implementing Trellix XDR, I have noticed positive impacts on my organization."
"Trellix XDR has impacted my organization positively as it's a security solution that protects us from threats."
"The analytics assessment and flexibility of the platform are valuable."
"Because Trellix gives us multiple types of modules, we are using a single ePO console for multiple solutions including application control, DLP, and XDR."
 

Cons

"They've been having some issues with updating their endpoint agents, and it has been quite frustrating."
"It's more focused on network communication. If a customer wants to increase the level of protection and start working with documents, it's impossible to integrate these features into the system. It's more of a communication-oriented system than a content security-oriented system."
"There are some false positives. What our guys would have liked is that it would have been easier to manipulate as soon as they found a false positive that they knew was a false positive. How to do so was not obvious. Some people complained about it. The interface, the ESM, is not user-friendly."
"While using Cortex, I noticed some aspects that could be improved, such as increasing the synchronization speed between XDR and Xnor."
"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."
"It takes time to scan the servers and devices."
"There is a severe gap in functionality between Windows, Linux, and Mac versions. For example all folder restriction settings are Windows only. Traps 5.0+ does not have SAML / LDAP integration."
"The solution lags to the real-time scenarios here and there."
"Areas that have room for improvement include user interface and integration."
"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."
"Trellix XDR should get involved in AI security itself."
"We have left Trellix XDR. The pricing was the main factor because the features were not there and they were charging more from us."
"I believe Trellix XDR could improve better visualization of attack paths and threat relationships."
"The EdgeGear solution is an area that requires attention, specifically regarding AI solutions and intelligence features."
"The platform should enhance compatibility with all other SIEM solutions."
"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 CPU utilization is very high with Trellix XDR; we are getting multiple types of CPU utilization from the EPP solution, with the EPP agent reaching as high as 80 percent CPU utilization, which creates big challenges for us."
 

Pricing and Cost Advice

"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"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."
"In terms of the cost Cortex XDR by Palo Alto Networks is very expensive because we are a Mexican company and when you translate dollars to pesos the cost is very high. The solution is very expensive for Mexican companies. I understand that they have international prices, but I do not think it offsets the price enough for many companies in countries, such as Mexico. The amount it is reduced is not a massive percentage."
"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."
"This is an expensive solution."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"The price of the solution is high for the license and in general."
"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."
