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

"The solution's most valuable feature is its ability to rapidly detect certain hardware files."
"The most valuable feature is that you can select remote access of any machine for sandboxing."
"From the Palo Alto side, whatever they buy, they integrate that really well into their integration suite, and that makes a massive difference."
"Cortex XDR by Palo Alto Networks has accelerated the response time for my security team, so we have been able to resolve issues faster than usual."
"It has absolutely improved the way our organization functions, we are more secure, it is giving us more peace of mind, and it has found malicious activity happening on our endpoints that probably would not have been detected if we didn't have it."
"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."
"The policy configuration is great, the granularity of policies that are available is very helpful, it is straightforward to set up, and it has pretty much everything we need and works well within the Palo Alto ecosystem."
"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

"When it comes to core analysis, and security analysis, Cortex needs to provide more information."
"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."
"In general, the price could be more competitive."
"It's not an ideal choice for smaller businesses, as you need a minimum of 200 endpoints to even use the solution at all."
"When it comes to malware files, it should be a little quick because, at times, it would give a wrong result in the sense of what it might be on malware, even if it still might be a normal one."
"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."
"There are some false positives."
"It is an enterprise-level solution. Its price could be less expensive."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"The price is on the higher side, but it's okay."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"Its pricing is kind of in line with its competitors and everybody else out there."
"It has reasonable pricing for the use cases it provides to the company."
"The price was fine."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"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."
