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

"Cortex XDR by Palo Alto Networks has helped lighten the load of our security analysts because it was the major tool that we were using and the one we utilized most."
"Cortex is a very good total solution on the endpoints."
"The stability of this product is very good."
"This software helps us understand any issues that may arise when someone is not at work."
"It's very stable. I've never experienced downtime for the ASM console or ASM core."
"I recommend this solution to others because it is easy to manage, reliable, and overall good to use."
"It has absolutely improved the way our organization functions, we are more secure, it is giving us more peace of mind, and it has found malicious activity happening on our endpoints that probably would not have been detected if we didn't have it."
"I generally believe that Cortex XDR by Palo Alto Networks is probably the best in the market right now."
"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."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"Tanium's most valuable feature is its instant discovery aspect."
"The security features are very valuable."
"For incident response tasks, all these tasks can get done in minutes with minimal disruption to the end-user."
"The most valuable features of this solution are the consolidation of all historical data on device endpoints, security drivers, firmware, and Software version gaps."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."
"Tanium is highly scalable."
 

Cons

"It'll help if customization was easier."
"Cortex XDR by Palo Alto Networks is a strong tool, but it is true that digesting information sometimes makes the tool go a little bit slower."
"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."
"I think sometimes Cortex XDR agent automatically stops event capturing from the device, and then even the dashboard does not get any notifications from the agent."
"There are some false positives."
"Currently, we are monitoring all USB drives and ports but we would like to improve our device control capabilities."
"The solution should offer more dashboards and they should be better customized."
"It would be good to have a better way to search for a file within the UI."
"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’s scalability could be improved."
"The most painful thing is the interface. It's a bit unclear sometimes."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
"There are downsides and drawbacks in Tanium, and there is room for improvement from my perspective."
"The solution needs to improve the reporting and tracking capabilities."
"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."
"Any movement into a SaaS solution has challenges since the processes and data flows are not well defined. Hence, you need to build it at the same time."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
 

Pricing and Cost Advice

"The price of the solution is high for the license and in general."
"The pricing is a little bit on the expensive side."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."
"The pricing is okay, although direct support can be expensive."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"Cortex XDR's pricing is ok."
"It’s a single license platform."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"There is an annual license required to use this solution."
"It is higher than some competitors in the market."
"The solution offers value for money."
"The solution is expensive but it's a good investment."
"It's an expensive solution. It would be nice if the cost were lower."
