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

"Cortex XDR lets us manage several clients from the same console, and its endpoint defense is more advanced than traditional antivirus."
"The multi-layered approach to the product gives you confidence that it will stop exploits, ransomware, worms, or viruses from compromising endpoints, essentially providing peace of mind."
"The scalability of Cortex XDR by Palo Alto Networks is very good."
"It's a perfect solution. It integrates well into the environment."
"The tool's use cases are relevant to security."
"Cortex XDR is stable, offering high quality and reliable performance."
"The product is very good, it has caught a lot of exploits that most products would not."
"It detected stuff that other things wouldn't detect."
"The integration of data from firewalls and Active Directory is most valuable."
"The solution has an investigation feature, which is useful for building storylines."
"The integration of data from firewalls and Active Directory is most valuable."
"Cybereason XDR's most useful feature is the investigation."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"While using Cortex, I noticed some aspects that could be improved, such as increasing the synchronization speed between XDR and Xnor."
"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."
"It's more focused on network communication. If a customer wants to increase the level of protection and start working with documents, it's impossible to integrate these features into the system. It's more of a communication-oriented system than a content security-oriented system."
"It takes time to scan the servers and devices."
"The price could be a little lower."
"It would be good to have a better way to search for a file within the UI."
"We have found that there are times Cortex XDR by Palo Alto Networks does not detect some of the viruses, we have to use another protection solution called Kaspersky."
"The dashboard could use some significant improvement, just making it more useful with more information. It has a limited amount of information right now. It is customizable, but I'd love to see a better out-of-box dashboard."
"The one thing we sometimes have issues with is its integration with other security applications like antiviruses."
"There could be more integrations with other data sources like NDR systems."
"Cybereason's customer support could be better."
"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."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"The pricing is okay, although direct support can be expensive."
"The price of the product is not very economical."
"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"Its pricing is kind of in line with its competitors and everybody else out there."
"Our customers have expressed that the price is high."
"I am using the Community edition."
"The solution is cheaper than Microsoft Defender. It has a subscription and no standard license."
"It’s a single license platform."
