The problem isn't a lack of security data, it's too much noise

Logs, flows and events arrive by the thousand per second. Without correlation, the security team looks for the needle in the haystack while the attacker works. That's what a SIEM is for.

Correlation that makes sense

QRadar collects logs, network flows (QFlow) and events from the whole estate and correlates them with rules and machine learning: thousands of events become a few offenses with a magnitude score weighing severity, relevance and credibility. The single event is harmless, the sequence isn't — QRadar sees the sequence.

UEBA adds behavioral analysis: the user downloading 100× the usual, the compromised account moving at night. And X-Force threat intelligence enriches offenses: the malicious IP is already known.

The Power world too, finally in the SIEM

AIX, IBM i and HMC logs and audit journals enter the SIEM: the company's most critical system stops being the security blind spot. And SOAR turns the playbook into automation: containment in minutes, with the operator approving, not typing.

All traced for NIS2/DORA audit: logs, evidence and compliance reporting ready.

How we start

A misconfigured SIEM is a cost that doesn't protect: it must be sized and tuned.

• Monitoring assessment: what you see, what you miss
• Sizing and tuning of correlation rules
• IBM i and AIX brought into the SIEM
• 24/7 SOC/NOC with reports and continuous improvement
