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.

Integration of multiple firewalls enables advanced threat detection
The integration of data from firewalls and Active Directory is most valuable. Cybereason XDR facilitates two-way communication, where the firewall sends data to the Cybereason system, and it can communicate with the firewall to stop unwanted communication. Customers can deal with multiple types of firewalls with ease. The behavioral analytics help detect advanced threats when attackers use existing software. The multilayered protection approach, including NGAV, integrates XDR detection with antivirus to assess and counter threats effectively.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"My advice for anybody who is considering Cortex XDR is that it is a complete solution, and has very good features."
"Based on my experience, I would recommend Cortex XDR by Palo Alto Networks to other people."
"It'll not slow down your system when compared to others."
"Based on my experience with Cortex XDR by Palo Alto Networks, I highly recommend it due to its quick response to zero-day attacks and low utilization from end-user devices."
"Cortex XDR lets us manage several clients from the same console, and its endpoint defense is more advanced than traditional antivirus."
"The stability of this product is very good."
"The solution's most valuable feature is its ability to rapidly detect certain hardware files."
"Automation and playbooks have helped me significantly, as Cortex Xnor's playbooks predefine the workflow of the automation, such as response processes, alert triggering, and enriching the context, efficiently detecting and blocking malicious attacks with firewalls while eliminating workload and speeding responses for next-generation operations."
"The integration of data from firewalls and Active Directory is most valuable."
"Cybereason XDR's most useful feature is the investigation."
"The solution has an investigation feature, which is useful for building storylines."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"It would be good if they could make an exception for applications. Sometimes, it can be a bit of a challenge to make exceptions for certain applications that have been used as rogue."
"In general, the price could be more competitive."
"The GUI could be improved."
"There are some third-party solutions that are difficult to integrate with, which is something that can be improved."
"There are some false positives."
"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."
"Cortex XDR by Palo Alto Networks is a very good product, but financially, it is very expensive, so the company should look into that area."
"It'll help if customization was easier."
"There could be more integrations with other data sources like NDR systems."
"Customer service is rated as a five out of ten. When they work and reach the right level, they are helpful, but getting to the right person can be time-consuming."
"Cybereason's customer support could be better."
"The one thing we sometimes have issues with is its integration with other security applications like antiviruses."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"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."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."
"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."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"The price of the solution is high for the license and in general."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"The solution is cheaper than Microsoft Defender. It has a subscription and no standard license."
"It’s a single license platform."
