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.

"The solution is a new generation XDR that has a lot of artificial intelligence modules."
"We have found in our test Cortex XDR by Palo Alto Networks to be a very good tool."
"I've found the solution to be highly scalable for enterprises."
"It has pretty much everything we need and works well within the Palo Alto ecosystem."
"It blocks malicious files, prevents attacks, and doesn't require many updates because it is a very light application."

Cons

"The downsides of Cortex XDR by Palo Alto Networks are that in many incidents, when I enter the causality chain, there are numerous logs."
"For Cortex XDR by Palo Alto Networks, if I had to point out improvements, I would say the UI is still somewhat difficult for beginners."
"The GUI could be improved. It's a little bit cumbersome. It could be more user-friendly."
"A potential area of improvement for Cortex XDR by Palo Alto Networks is the cost."
"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"Currently, if you use Palo Alto endpoint protection as the only solution it's very complicated to remove pre-existing threats."
"However, if you do not have Palo Alto in your environment, you are paying these additional services just for Cortex XDR by Palo Alto Networks, so it is not a cost-effective solution."
"Cortex XDR should have a lightweight agent, and the agent size should not be heavy."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"The pricing is a little bit on the expensive side."
"The tool's price is moderate."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."

"Cortex XDR's pricing is ok."
"It has reasonable pricing for the use cases it provides to the company."
