I really like the feature we have with the logs, that if there are any credit card numbers being used, like a PII, you can just use rejects and you can mask it. This is a really good feature in QRadar.
QRadar shows very effective correlations. If you combine all the logins plus user behavior and the current intelligence, it gives a very good correlation for business. I think it reduces the false positives in user activity monitoring because there is a lot of social information to correlate with other data.
