TL;DR: Enriching endpoint, network, and cloud alerts with IOCs from threat intelligence feeds can improve prioritisation, reduce false positives, and speed incident response, according to Wazuh’s integration with OpenCTI. For SOC teams, the key shift is not more alerts but better context, because detection quality depends on how quickly telemetry is matched to known threat activity.

Questions worth separating out
Q: How should security teams use enrichment to improve alert triage?
A: Security teams should use enrichment to turn an alert into a decision, not just an observation.
Q: Why do threat intelligence feeds improve SOC response times?
A: They reduce the time analysts spend asking whether an event is meaningful.
Q: What breaks when enrichment scripts and API tokens are not governed?
A: The workflow loses trust quickly.
Practitioner guidance
- Validate feed quality before routing alerts to analysts Confirm that OpenCTI connectors are active, current, and aligned to the event types you actually investigate, then review match confidence and stale IOC handling in the enrichment workflow.
- Protect enrichment scripts and API tokens as privileged assets Store tokens outside general configuration files, restrict file permissions, and review any custom integration script with the same discipline you apply to other security automation code.
- Map alert groups to the threat scenarios you investigate most often Limit enrichment to event classes where IOC correlation changes decisions, such as authentication failures, DNS anomalies, and malware-related file activity, so the workflow stays operationally relevant.

Threat intelligence enrichment is a triage control, not a detection strategy. Correlating Wazuh alerts with OpenCTI-style IOC data improves analyst decisions, but it does not solve coverage gaps in telemetry or authentication. Security teams still need solid endpoint, network, and workload controls before enrichment can add value. The practical conclusion is that enrichment should sit on top of good detection engineering, not replace it.
A question worth separating out:
Q: How do teams decide which alerts should be enriched with threat intelligence?
A: Focus enrichment on alert classes where external context changes the decision, such as authentication failures, suspicious DNS queries, malware events, and unusual network connections. If enrichment does not change prioritisation, escalation, or containment logic, it is likely adding complexity without enough operational value.
