Automated threat response and behavioral control improve security measures
I recommend adding a data loss prevention (DLP ( /categories/data-loss-prevention-dlp )) solution to Cortex XDR ( /categories/extended-detection-and-response-xdr ) by Palo Alto Networks. The inclusion of this feature would allow the application of DLP ( /categories/data-loss-prevention-dlp ) policies alongside antivirus policies via a single agent and console, making it more competitive as other OEMs often offer DLP solutions as part of their antivirus products. Additionally, multi-tenancy and multi-cloud features are not available and should be considered for inclusion.

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

"If any application performs suspicious activities, such as changing registries or modifying other applications, Cortex XDR detects and blocks the entire application."
"The user interface of the solution is sophisticated and straightforward."
"WildFire AI is the best option for this product."
"The live terminal is probably the best thing ever. It gives you the access to get straight onto any machine."
"Stability is one of the features we like the most."
"The information the dashboard provides is very clear."
"The solution allows us to gain remote access without the user's knowledge and take the necessary actions on the device."
"The interface is easy to use and it is more up to date than our previous solution."
"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

"Cortex XDR could be improved with more GUI features."
"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."
"In general, the price could be more competitive."
"They are charging for Network Traffic Analyzer (NTA) services, so if the per GB data could be provided at a certain level free of cost or at the same cost which the customer is taking for the entire bundle, that would be better."
"Managing the product should be easier."
"Being able to filter the events to see those that are related to the actual alert would save time spent by the engineer."
"I don't like that they have different types of licenses. For example, if users select a license, they think they will have all the platforms they need to improve their network or security. But after some time, Palo Alto Networks changed their licensing, and some of the features that, for example, were free at the beginning now have a cost. I think the integration can be improved. For example, a lot of tools are just integrated through APIs."
"I recommend adding a data loss prevention (DLP) solution to Cortex XDR by Palo Alto Networks. The inclusion of this feature would allow the application of DLP policies alongside antivirus policies via a single agent and console, making it more competitive as other OEMs often offer DLP solutions as part of their antivirus products."
"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

"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"The cost depends on your chosen license type, like Pro or other licenses."
"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."
"The return on investment is from the user side because we have seen the performance of it increase the delivery time of the product if we are using too many web-based and on-premise applications. In indirect ways, we saw the return of investment in terms of performance and user satisfaction increase."
"The pricing is a little bit on the expensive side."
"It has a yearly renewal."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"It’s a single license platform."
