Cloud security has improved as AI-driven runtime protection detects threats and reduces incidents
In my opinion, Cortex Cloud by Palo Alto Networks could be improved or enhanced in various ways. I don't have an idea about that yet because for that you actually need to use two or three different other tools to make a basic comparison. If you ask me how good the tool is, I would fairly rate it quite high. The tool is very popular, and customers can already see that it is one of the cloud leaders in the security space. The platform had a very good feature which provides documentation links about how to use a specific feature on the UI. It takes you to the proper documentation page where it suggests what to do and tells you about the steps that need to be done for a resource deployment. My thoughts about improving the product which I believe could greatly aid vendors is that it used to be a very user-friendly tool, but now they have incorporated everything under one umbrella. It has XDR, XSOAR, and Cortex Cloud by Palo Alto Networks. Before, we used to have separate modules and separate environments for each of these capabilities or features. Right now, it is a little complex and users would take their own time to know the tool better. This is something that would have been way better, but I would say there would be different opinions on this. Talking about user-friendliness, it has decreased now.

Centralized security testing has improved vulnerability remediation and compliance reporting
I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

Pros

"The most beneficial aspect of Cortex Cloud by Palo Alto Networks and Palo Alto in general is that there is a single platform for all cloud providers for securitization."

"Cortex Cloud by Palo Alto Networks' cloud runtime security in terms of stopping attacks in real time is impressive."
"I have absolutely seen improvements in our incident close rates, with mean time to detect and respond reduced significantly, sometimes by at least forty to fifty percent."
"Cortex Cloud by Palo Alto Networks has impacted our organization positively by keeping our machines secure and our team using the dashboard to find issues quickly."
"The AI and automation features in detecting and responding to high-risk threats are impressive; it's one of the best tools regarding AI technology and unifies security in one platform in real-time, improving vulnerability analysis, incident response, and compliance reporting."
"I have seen several benefits from using Cortex Cloud by Palo Alto Networks: It was easy to use and easy to migrate from the IBM platform."
"The capabilities of Cortex Cloud by Palo Alto Networks are valuable because it is the best product in the market."
"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."
"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."
 

Cons

"From the commercial perspective, we have some limitations because Palo Alto has a minimum number of users of endpoints set at 200, which is quite high for the Italian market."
"My thoughts about improving the product which I believe could greatly aid vendors is that it used to be a very user-friendly tool, but now they have incorporated everything under one umbrella."
"The pricing is high, making ROI challenging to justify, especially during transitions between solutions."
"Overall, I rate Cortex Cloud by Palo Alto Networks as an eight out of ten. I think that it could improve on price, as I know that the Google solution has the best price, and this is one of the conditions."
"Some aspects of the GUI can be confusing and make it difficult for me to find certain options or navigate where needed."
"As per my experience with Cortex Cloud by Palo Alto Networks, the UI could be simpler."
"The negative aspects or areas for improvement in the product include the fact that the cost might be a bit high, which challenges commercials, but not technically."
"Cortex Cloud by Palo Alto Networks is not the cheapest solution in the market, but I know that is the best solution for SOC and Cloud once have all tools to connect cloud issues with SOC procedures, because we are partners with T-Systems."
"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
