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.

Cons

"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."
"There are some third-party solutions that are difficult to integrate with, which is something that can be improved."
"Cortex XDR by Palo Alto Networks could improve by adding a sandbox feature to better compete with their competitors which have it."
"When it comes to core analysis, and security analysis, Cortex needs to provide more information."
"Cortex XDR by Palo Alto Networks is a very good product, but financially, it is very expensive, so the company should look into that area."

Pricing and Cost Advice

"The cost depends on your chosen license type, like Pro or other licenses."
"Cortex XDR’s pricing is very reasonable."
"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 is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"I don't have any issues with the pricing. We are satisfied with the price."
"Cortex XDR's pricing is ok."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
