Episode notes
Real-Time NetFlow Enrichment
- NetFlow Optimizer enriches NetFlow records with additional context like user identity and GeoIP location before sending to monitoring systems.
- This pre-enrichment saves analysis time and improves accuracy in troubleshooting and investigations.
Reduce NetFlow Volume Intelligently
- Use intelligent consolidation to combine similar NetFlow records, reducing data volume significantly.
- Ignore ephemeral client ports to further decrease flow volume without losing valuable information.
Value of Lateral Traffic Monitoring
- Monitoring lateral traffic inside the network reveals threats missed by edge-only monitoring.
- Identifying unusual lateral data flows helps prevent data exfiltration and detect unauthorized access.
