The feedback that we have given to the Palo Alto Networks team is that the UI can be improved. When you press the "back" button on your browser from the Investigate tab, the query that you're working on just disappears. It won't keep the query on the "back" button. Also, the way the policies are structured and the alerts are created could be better. It requires a lot of manual work to search through the policies when creating an alert. These are minute nuances. They are not major issues and are more about convenience than they are product bugs.
In terms of improvement, there are some small things like hardening and making sure the Linux resources are deployed well but that's more at an operational level. Day-to-day, we do find a lot of issues but having a tool to help us with them is what we want because manually, it's not feasible for us. Other than that, we not really looking for any other add-ons or plug-ins because that was our core problem.
In our testing, we have found the Check Point product CloudGuard Dome9 to be more user-friendly at this point. Palo Alto Prisma's interface was not as user-friendly. Palo Alto should work on this part of its solution to be more competitive with ease-of-use. I do not feel Palo Alto is short of any features, but if we compare the two side-by-side, I think the user interface for Palo Alto needs to be improved to make it at least as good as Dome9.
I'm not sure about areas for improvement on the solution, however, I do think the compliance and dashboarding could be better. The innovation side of the solution could be more efficient and more detailed.
