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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

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

"Has great threat detection capabilities."
"Cortex XDR can integrate the firewalls and determine the tendencies of the attacks. It's a new generation antivirus, with protection endpoints and detection response. It is very easy to use and everybody can operate the solution."

"The initial setup isn't too bad."
"We have found in our test Cortex XDR by Palo Alto Networks to be a very good tool."
"The solution allows us to gain remote access without the user's knowledge and take the necessary actions on the device."
"Traps has drastically reduced our endpoint attack surface via advanced detection capabilities, sandboxing of never before seen programs, and by drastically limiting where executables can launch in the first place."
"There are a lot of lead solutions in this space, however, Palo Alto is number one."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"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."
"The analytics assessment and flexibility of the platform are valuable."
"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."

"Since implementing Trellix XDR, I have noticed positive impacts on my organization."
"The best features of Trellix XDR are the in-depth analysis it provides."

"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."
 

Cons

"Technology evolves every day, so it would be nice if it gets more secure. It can also have more integration with other platforms."
"The onboarding process could be better."
"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."
"This is a very costly product."
"There are some false positives."
"The MAC agent is not as robust feature-wise as the PC version."
"We have found that there are times Cortex XDR by Palo Alto Networks does not detect some of the viruses, we have to use another protection solution called Kaspersky."
"The product's pricing could be better."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"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."
"The platform should enhance compatibility with all other SIEM solutions."
"The EdgeGear solution is an area that requires attention, specifically regarding AI solutions and intelligence features."
"Customer support is average, depending on who the call gets to, escalation, and how quickly they respond."
"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."
"Price is the main area for improvement in the product."
 

Pricing and Cost Advice

"The cost depends on your chosen license type, like Pro or other licenses."
"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."
"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 solution is expensive. It's pricing is on a yearly-basis."
"The pricing is a little bit on the expensive side."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"Very costly product."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"It’s a single license platform."
