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.

Provides efficient network access control, but its support services need improvement
We use the product for network access control The product has valuable features for cloud IoT device enhancement, intelligent threat detection, etc. We can easily quarantine any computer if it gets hacked. The product's support services have limitations. We have to connect with their senior…

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

"Best solution for avoiding security breaches, malware attacks, and other kinds of security issues."
"Since they've done their most recent update, the ease to isolate endpoints is valuable. If we find one where there is a virus on it, we can easily isolate it. We don't even have to contact the user. We don't have to manually take them off the network. We can easily isolate them."
"Monitoring is most valuable."
"I like that the product has behavior-based detection which offers many benefits over signature-based detection."
"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."
"One of the things that I enjoy the most is using policy extensions. It's like having host firewalls to control USB connections. I think it's a wonderful tool to restrict use when connecting to our computers. Another important tool is Home Insights. That is an add-on to the Cortex solution. I like that because we can see all the vulnerabilities in the environment and control what assets are connected to our network."
"Monitoring is most valuable."
"The protection offered by this product is good, as is the endpoint reporting."
"The product has valuable features for cloud IoT device enhancement, intelligent threat detection, etc."
"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

"I feel that it should not be a licensed activity because a feature should allow us to see applications running on end devices."
"If he is using a smaller company, he can depend on some other tools because Cortex XDR by Palo Alto Networks is a bit expensive."
"Product might have some bugs."
"It's not an ideal choice for smaller businesses, as you need a minimum of 200 endpoints to even use the solution at all."
"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."
"In an upcoming release, the solution could improve by providing hard disk encryption."
"As an improvement, I would like to see enhanced connection speeds."
"A better pricing plan would make this product more competitive."
"The product is more expensive than other vendors in terms of features."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"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 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."
"This is an expensive solution."
"Cortex XDR’s pricing is very reasonable."
"The tool's price is moderate."
"This is an expensive solution."
"Traps pays for itself within the first 16 months of a three-year subscription. This is attributed to OPEX savings, as security teams spent less time trying to identify and isolate malware for analysis as a result of a reduction in malware incidents, false positives, and breach avoidance."
"It has a yearly renewal."
"The product is more expensive than other vendors in terms of features."
