Hot take: QRadar's 'AI' capabilities are just basic correlation with a fancy label.

I've spent the last six months evaluating SIEM platforms, with a deep dive into QRadar 7.5.0. The marketing push around its "AI-driven insights" is, frankly, misleading. After tearing apart the workflows and testing the "offenses," it's clear the core engine is still fundamentally rules-based correlation with statistical weighting slapped on top.

Here's what I mean. The "AI" label seems to be applied to two things:
* **Anomaly detection dashboards:** These are essentially rolling baselines of event counts. A spike in "Failed Logins" from a source gets flagged. This is simple statistical deviation, not machine learning understanding of context. You can replicate 80% of it with a custom rule and a time series chart.
* **Offense "confidence" scoring:** A high-confidence offense appears to just be one that hits on multiple correlation rules simultaneously. If a single source triggers "Malware C&C Beacon," "Unusual Outbound Traffic," and "Data Exfiltration Protocol" rules, the confidence is high. This is multi-condition correlation, not predictive AI.

I set up a test lab with simulated traffic. The so-called "machine learning" models required an impractical amount of "clean" baseline data to configure and still generated overwhelming false positives on any unusual but legitimate activity (e.g., a scheduled bulk data transfer). Tuning them was identical to tuning a traditional rule: adding exceptions and whitelists.

My benchmark shows QRadar's real strength is in its **correlation engine and app ecosystem**, not any genuine AI. For the price point, I expected more than what amounts to:
```sql
-- Simplified analogy of what's happening under the hood
SELECT source_ip, COUNT(*) as event_count
FROM events
WHERE log_source_type = 'Windows'
AND event_name = '4625' -- Failed Login
GROUP BY source_ip, HOUR(event_time)
HAVING event_count > (baseline_avg * 3)
```

Has anyone else done a technical tear-down and reached a different conclusion? I'm looking for reproducible evidence of true behavioral modeling, not just vendor demos showing the pre-tuned "Sample Offenses." What specific use cases have you found where QRadar's AI demonstrably outperformed a well-written correlation rule?


Show me the query.

That tracks. The "AI" label is thrown on anything that isn't a straight boolean rule now. I see the same pattern in other products.

What was the performance overhead on your simulated traffic when you had those "ML" modules enabled? In my experience, enabling that stuff often just adds a flat 15-20% load on the event processors for minimal gain.

You can spot the trend by looking at their release notes. The shift from calling it "correlation" to "cognitive engines" happened around version 7.3 with no major architectural change. It's a marketing rename.


Benchmarks don't lie.
