When it sends the log source, QRadar generates a lot of noise and false positives. LogRhythm logs when the alarm rules are disabled, so it doesn't generate any noise when sending the log source. I think LogRhythm's one, this one too. QRadar, we have to cure it all the time. It's only this advantage with QRadar.
I would also like to see more integration with other vendors. IBM doesn't integrate well with products from China, like Huawei. Many Middle Eastern customers are switching to Huawei from American vendors like Cisco because of the price. In most RFPs, Huawei wins because it costs less.
IBM needs to integrate better with Huawei. I opened one case with IBM, and they told me to submit a request for enhancement so they could write the correct DSMs to integrate with Huawei. We were very disappointed. Customers who want to implement QRadar or LogRhythm need to consider all the other components. The environment needs to be homogenous to avoid problems due to a lack of integration.
My old company used QRadar, so I still use it sometimes when I consult for them. They get stuck on a few things. I also worked on vulnerability discovery. Right now, my current customers are migrating from QRadar to LogRhythm.
QRadar is built around Red Hat Linux, which is highly robust.
IBM's support for QRadar could be improved. Sometimes it takes them two days to reply to a low-priority case. However, it tasks them about 1.5 hours to respond to a more serious case. Sometimes our customer service will think it's a priority one case, so he asks me to open it as priority one, then IBM reduces it to two or three.
We don't have any security appliances from Huawei, but they have the best technical support. We have engineers everywhere with CRM, and they call you after the problem is resolved. IBM closes the case, and that's it. It's a very restricted environment.
QRadar is reasonable compared to LogRhythm.
I rate IBM QRadar nine out of 10. If you're going to use QRadar, you have to be familiar with it and know all the components. IBM offers free appliances, like data nodes, that offload many processes from the collectors and the processors.
Every engineer must understand the overall portfolio to add some value to the solutions. If a solution isn't integrated with other solutions, they are only collectors. You need to tune the rules and be up to date with the Mitre Att&ck framework all the time.
