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.

Quotes from Members

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

Pros

"After installing this solution, it identified, blocked, and provided the complete attack chain, which was very helpful."
"These days it's machine-learning technology and behavior-based analytics features that make us more secure."
"The product's initial setup phase is very easy."
"Their XDR agent and their behavioral indicators of compromise (BIOC) are pretty nice. Their managed threat hunting is also pretty nice. They also have WildFire, which is a service for actively looking for malware. It's quite useful."
"The ability to kind of stitch everything together and see the actual complete picture is very useful. I guess you'd call it a playbook. Some people call it the forensics analysis of what was happening on particular endpoints when they detected some malicious behavior, and what transpired before that to cause that. It is also very user friendly. The way they have done everything and integrated all the solutions that they've purchased over the years to make it a very seamless, effective product is very good. One thing about Palo Alto is that they take the products or services that they purchase and make them seamless for the end user as compared to some companies that purchase other companies and then just kind of have their products off to the side or keep different interfaces. Palo Alto doesn't do that."
"It detected stuff that other things wouldn't detect."
"When the pandemic started, Palo Alto came up with many solutions, which helped with the quick shift from on-premises to the cloud."
"I generally believe that Cortex XDR by Palo Alto Networks is probably the best in the market right now."
"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

"The encryption is not up to the mark."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"Limited remote connection."
"They have the worst support, as a company, that I have ever worked with, as they are difficult to get a hold of and keep on the phone. They don't know what they are talking about when you get them on the phone. They don't like to respond to messages when you send them to them. They like to "research problems" for weeks on end, then pass you off to somebody else."
"Cortex XDR by Palo Alto Networks could improve by offering remote management. It would be useful to look at the client's issue to fix it."
"If Palo Alto reduces the pricing slightly for their products, it would make them more scalable in markets such as India and globally for cybersecurity."
"The solution should offer more dashboards and they should be better customized."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"Its pricing is kind of in line with its competitors and everybody else out there."
"Our customers have expressed that the price is high."
"The price of the solution is high for the license and in general."
"Cortex XDR’s pricing is very reasonable."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"The pricing is okay, although direct support can be expensive."
"The pricing is a little bit on the expensive side."
