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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

"Its ability to deliver a substantial amount of security intelligence greatly enhances and optimizes our security operations program."
"It does a better job of identifying anomalies that are more likely to be incidents of compromise without as many false positives or false negatives."
"Since implementing Cortex XSIAM, incident response times have been significantly reduced by approximately twenty percent."
"The most valuable feature is the integration capability."
"It is an effective solution in terms of performance and functionalities."

Cons

"I would rate the overall stability a six or seven, as we have only used it for a few months and need a year of experience to provide a full assessment."

"Cortex XSIAM is on the expensive side and requires substantial improvement in pricing."
"The support could be a bit faster."
"I would say that the thing that maybe needs a bit more improvement is the firewall because I have seen some things there that are kind of hard to manage."
"Cortex XSIAM is pretty expensive, and the licensing process is not very comfortable compared to CrowdStrike."
"The solution’s pricing and technical support could be improved."
"Cortex XSIAM needs improvements in terms of data onboarding, parsers, and third-party integration supports."
"In the future, I would like to see threat intelligence included."

"IBM Watson for Cyber Security is very simple to license and is priced well."
"The price of this solution should be lower, although I understand why IBM charges a premium price."
