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.

Quotes from Members

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

Pros

"Palo Alto is the core of the security infrastructure in the environment."
"I recommend this solution to others because it is easy to manage, reliable, and overall good to use."
"The tool is designed to scale for large enterprises and handle large volumes of data."
"They have a new GUI which is just fantastic."
"One of the main benefits of the solution is its intelligence to correlate the events into an incident."
"Stability is one of the features we like the most."
"We have a complete overview of all our PCs and it's very easy to handle and to use the interface."
"If you are looking for security, mainly for advanced threat prevention from ransomware and malware attacks, I would recommend Cortex."
"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."
 

Cons

"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"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."
"There are some third-party solutions that are difficult to integrate with, which is something that can be improved."
"When it comes to core analysis and security analysis, Cortex needs to provide more information."
"The solution lags to the real-time scenarios here and there."
"The solution eats memory of the computer, unlike anything I've ever seen."
"Every 30 or 40 days, there's a new version and we need to go and make sure our customer's laptops are upgraded."
"The server sometimes stops continuously to check things so it would be helpful to receive access updates or technical reasons."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"The tool's price is moderate."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"Cortex XDR is a costly solution."
"The price is on the higher side, but it's okay."
"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."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"I don't recall what the cost was, but it wasn't really that expensive."
"The pricing is a little high. It is per user per year."
