The features that I have found most valuable in QRadar are its data enrichment, use case creations, and adding references - those kinds of features are very good. Also, QRadar's event filtration and device integration are perfect.
Actually, we are looking for another product because a customer is demanding different products and they're not going with QRadar, hence we are trying to compare QRadar with other solutions like Securonix, Splunk, Exabeam, LogRhythm. Otherwise, all our customers are happy with QRadar.
I'm doing integrations and deployments for QRadar. So, in regards to integration and deployment, QRadar is very easy as compared to other products.
