SIEM Is Not Dead: How to Use Logs and AI More Intentionally

Summary
A Huntress author argues SIEM remains useful when organizations retain security- and compliance-relevant logs, use AI selectively for correlation and investigations, and divide monitoring and response responsibilities between providers and internal teams.
Key points
- The author argues that ingesting every available log can drive costs and alert noise without ensuring the data is useful.
- On-demand AI log analysis may shift spending from storage to compute, while depending on source retention, API availability and rate limits, and compliance requirements.
- The recommended approach is to retain logs that support threat detection or investigation, and those required by auditors, regulators, or insurers.
- The article suggests applying AI after filtering, for tasks such as correlating endpoint, identity, and log data, summarizing activity, and adding triage context; analysts and detections remain responsible for deciding whether activity is malicious.
- Managed security providers can handle broad threat monitoring, detection tuning, triage, and remediation, while internal teams provide context about approved tools, changes, and unusual activity.
- Organizations should agree in advance on incident-response roles and which containment or business decisions require their approval.
