Use Case — SIEM Cost Reduction
Most Teams Don’t Send NetFlow to their SIEM.
They Can’t Afford to.
Raw NetFlow, sFlow, and IPFIX are high-volume by nature — duplicated across collection points, broken into thousands of micro-flows, stripped of context. Sending it directly to your SIEM inflates ingest volume and drives up licensing costs without improving visibility.

HOW IT WORKS
Four stages of volume reduction — before your SIEM billing meter.
NFO sits before your SIEM and applies intelligent reduction at every stage.
All processing happens inside NFO — your SIEM only receives the optimized output.
Deduplication
Removes duplicate flow records reported by multiple collection points across your network. The same conversation shouldn’t be billed twice.
Aggregation
Collapses thousands of micro-flows into single summarized records. Full traffic intelligence, a fraction of the event count.
Flow Stitching
Combines bidirectional flows into unified session records — reducing record count by an additional 50% while preserving full analytical fidelity.
Normalization
All flow sources, NetFlow, IPFIX, sFlow, J-Flow, and cloud flow logs from AWS, Azure, GCP, and OCI, normalized into a single consistent format. One pipeline, one schema.
ENRICHMENT
Fewer events. More context. Better detection.
Volume reduction alone isn’t the full story. Raw flows contain IP addresses — your
SIEM needs context. NFO enriches every flow record inside the pipeline before delivery.
User Identity
Resolves IP addresses to Active Directory users, or Okta, or Microsoft Entra ID accounts — so analysts investigate people, not addresses.
Threat Intelligence
Matches IPs against reputation feeds so high-risk connections surface immediately in SIEM correlation rules — no additional enrichment steps required.
VM & Cloud Metadata
Tags flows with instance names, VPC IDs, and region data for cloud environments — unifying on-prem and cloud visibility in a single stream.
GeoIP and ASN
Adds country, city, and network ownership to every external connection. Spot anomalous geographic patterns immediately.
THE IMPACT
What 80–90% reduction means in practice.
Same network. A fraction of the ingest bill.
Whether your network generates 5,000 or 500,000 flows/sec, the reduction ratio holds. NFO applies the same deduplication, aggregation, and flow stitching logic regardless of scale — typically delivering 80–90% less volume to your SIEM billing meter.
NFO doesn’t reduce what your SIEM can see. It reduces what your SIEM has to store.
Same analytical coverage. 80–90% less volume.
Same analytical coverage. 80–90% less volume.
NFO reports your actual flow rate and reduction metrics during
the free trial — so you can calculate the impact on your SIEM
bill before committing.
