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.

Setup is smooth and management is seamless, while improvements in email filtering transparency enhance efficiency
For data correlation, we just haven't worked long enough with it to assess its impact on our overall threat response strategy. We prefer a system that simply informs us when there is a problem; we don't want to engage too much in threat hunting. Therefore, we're not looking to create a SOC from this, which is also why we moved from XDR to MDR. There are areas for improvement, including the difficulty in getting the right handles on the applied email filters. It's sometimes unclear why one email is treated as spam and another is not, even if they contain similar content. Making the process of how emails are treated a bit more transparent would be beneficial.

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

"Being a cloud solution it is very flexible in serving internal and external connections and a broad range of devices."
"We switched because there were a lot of added features with Palo Alto that Check Point didn't have, and it was an upgrade for us."
"The most valuable feature of Cortex XDR by Palo Alto Networks is its machine-learning capabilities. Additionally, there is full integration with other solutions."
"If you are looking for security, mainly for advanced threat prevention from ransomware and malware attacks, I would recommend Cortex."
"The solution's most valuable feature is the user interface."
"The one feature of Palo Alto Networks Traps that our organization finds most valuable is the App ID service."
"Cortex is the best tool for endpoint detection, and I have used it to verify hashes or domains to identify malicious activity, trigger playbooks that automate and gather endpoint logs, block malicious processes, and update incident tickets, showcasing end-to-end processes with automation in investigation and reducing the analysis workflow."
"There has been a significant reduction of approximately 70% to 80% in our internal MTTR and MTTD metrics, now around five to eight minutes whereas previously it was hours, which has helped tremendously."
"The HyperDetect feature in GravityZone XDR is effective."
"Since then, we are working with it, and so far, we have no problems; it's working smoothly with email security."
"I appreciate the overall utilization of AI to enhance security posture."
"I find that the auto-response capability is most valuable."
"It provides an in-depth analysis and gives recommendations, along with a historical search capability."
"Scalability is pretty easy. It's easy to increase the capacity. You can just add on licenses to the existing license, and the duration of the license can be adjusted. For example, you've already bought a license for a year, and you want to add some more users. We can just add on licenses for the remaining period so that the entire organization can have the same expiry date. That makes renewal easier."
"I would rate GravityZone XDR more than nine out of ten."
"The solution has an automatic patch management capability."
"ReliaQuest GreyMatter saves around 60% of time or resources."
"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."
 

Cons

"I have faced some issues with Cortex XDR by Palo Alto Networks; there is room for improvement in the sense that certain options prevent us from seeing and segregating data."
"Whenever the tool releases a new version when deploying the product across the organization, I feel like there are some disturbances in the CPU usage after upgrading the tool to the latest version."
"For Cortex XDR by Palo Alto Networks, if I had to point out improvements, I would say the UI is still somewhat difficult for beginners."
"It would be good to have a better way to search for a file within the UI."
"The solution lags to the real-time scenarios here and there."
"I have run into some detection issues with Cortex XDR. It needs to be better at detection of internal attacks."
"However, if you do not have Palo Alto in your environment, you are paying these additional services just for Cortex XDR by Palo Alto Networks, so it is not a cost-effective solution."
"The technical support is not very good. I find the process difficult."
"The solution’s pricing could be improved."
"Another area of improvement is CPU utilization. CPU utilization could be improved."
"There are areas for improvement, including the difficulty in getting the right handles on the applied email filters."
"It's not very mature, and additional costs are involved."
"The product could be improved by offering a single panel for the management of all Bitdefender products. Additionally, there might be a need to simplify the interface in the future."
"The resource consumption is high for Bitdefender GravityZone XDR, nearly using one gigabyte of RAM, especially on Windows 10 and 11."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"The tool's price is moderate."
"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 reasonable pricing for the use cases it provides to the company."
"I don't like that they have different types of licenses."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"The solution is expensive. It's pricing is on a yearly-basis."
"The cost depends on your chosen license type, like Pro or other licenses."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"It's not the price of the software itself that makes it expensive. It's because you have to buy a VM; you have to buy additional hardware. All those things make it slightly costlier."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a six out of ten."
