Unified security monitoring has simplified incident response and improved automated threat handling
The firewall side can make some improvements. I know the firewall on Cortex XSIAM is based on Windows. From what I have experienced so far, I have seen that the policies you can create are actually very in-depth. I mean, you can do most of the things and a lot of integration that you actually want. So if I want to choose to send things to WildFire, for example, I can choose to send it, I can choose to not send it. This basically offers flexibility to implement Cortex XSIAM in more standardized places where you maybe have a certification. I would say that the thing that maybe needs a bit more improvement is the fact that the one with the firewall because I have seen some things there that are kind of hard to manage. You do not really have a very easy way to manage those, unless you actually know where you have put them. So it is very inflexible. In the rest, you have a lot of playbooks that you can do and you can do lots of automation, which is actually easy to manage from what I have seen from my colleagues.

Unified log analysis has strengthened incident detection and supports continuous attack simulation
I do not have any areas for improvement in ArcSight Enterprise Security Manager (ESM) as I have not delved deeply into it; overall, it is a good package. I would like to see the detection and response features included in the next release of ArcSight Enterprise Security Manager (ESM), as security orchestration and automation are increasingly important.
