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.

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.

Centralized policies have improved remote endpoint control and have simplified data visibility
The integration is not simple and easy. It requires experienced users or people who have done the implementation. When certain policies are applied, they do not immediately push the policies. For example, we manage endpoint device USB access. We set a policy to block it, but it does not come into effect immediately. Sometimes it takes three or four days for it to reflect. That is a pain point. I have raised this issue with support as well, but they said that I need to limit the number of devices in the policy. In terms of application deployment, for us, it was seamless.

Quotes from Members

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

Pros

"Technical support is the best in class, in my opinion, because they have invested heavily in research and development."
"The most valuable features are the fact that it was running in the background and it would intercept any weird stuff, and the fact that it would send things directly to the cloud for sandboxing. It's quite practical."
"The integrations are out-of-the-box, as are the playbooks."
"The good thing about the product is that it's always scanning."
"Cortex XDR is a simple platform that's easy for administrators and users. You have a lot of flexibility to change or customize the features."
"The stability of this product is very good."
"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."
"Its ability to react to cyber data attacks is awesome. That is pretty much the use of it. What blows your mind is the ability to access your assets remotely and see what is actually going on with them. You can not only see them in a console. You can also react very rapidly to your assets that are compromised."
"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."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"I find the inventory and compliance features of Tanium to be the most impressive."
"I like the tool's incident response and security patching."
"The interrogation piece was the most valuable feature because it was very detailed."
"Tanium has made the process of detecting threats more proactive with its detection, so the process is easier and more efficient."
"The solution's technical support is very responsive."
"I would say Tanium is the best tool for vulnerability management."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
 

Cons

"The complexity and confusion regarding product variants, such as XDR, Forexiant, and Forexon, must be addressed."
"Managing the product should be easier."
"The solution should force customers to integrate with network traffic to see the full benefits of XDR."
"Limited remote connection."
"It would be better if they could educate the customers more. Some sort of seminars and roadshows will help educate the customers and show what the product can do."
"I feel that it should not be a licensed activity because a feature should allow us to see applications running on end devices."
"In an upcoming release, the solution could improve by proving hard disk encryption. If it could support this it would be a complete solution."
"If he is using a smaller company, he can depend on some other tools because Cortex XDR by Palo Alto Networks is a bit expensive."
"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."
"Tanium required local admin or root rights on Mac devices, which did not comply with our security policies. This made the solution less suitable for our restrictive environment."
"They could improve the UI."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"It is not really additional functions, or the features that are needed, rather the complexity would be reduced based on the number of modules required to put together a comprehensive operational security and risk compliance model."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"The solution lacks mobility."
"Our biggest issue with the solution is its lack of mobility."
"The solution needs to improve the reporting and tracking capabilities."
 

Pricing and Cost Advice

"The price was fine."
"Its pricing is kind of in line with its competitors and everybody else out there."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"The price is on the higher side, but it's okay."
"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."
"This is an expensive solution."
"Cortex XDR’s pricing is very reasonable."
"It’s a single license platform."
"The solution offers value for money."
"There is an annual license required to use this solution."
"It's an expensive solution. It would be nice if the cost were lower."
"It is higher than some competitors in the market."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"The solution is expensive but it's a good investment."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
