Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

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.

Micro-segmentation has transformed endpoint protection and now isolates internal threats effectively
Illumio can be improved in several areas based on our feedback. Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices. When these devices communicate within the network, loading the map or connections can cause latency, which needs improvement for a more user-friendly and faster experience. Regarding improvements to the interface, I believe we can add more features to the graphical user interface, such as proper logs. While the logs currently indicate what was blocked or allowed, clicking on a specific log should provide more information, such as which extra-scope rule is causing a denial, offering better analysis for troubleshooting.
