NetFlow Optimizer

NetFlow Logic makes network telemetry actionable inside the security and IT operations tools you already use — Splunk, Microsoft Sentinel, CrowdStrike, Datadog, and more. Its core product, NetFlow Optimizer™ (NFO), is a software-only processing engine that sits between your network infrastructure and your downstream platforms. NFO ingests raw flow data (NetFlow, IPFIX, sFlow, J-Flow) and cloud flow logs (AWS, Azure, GCP, OCI), then deduplicates, aggregates, and enriches every record before forwarding it — reducing volume by up to 90% while adding user identity, application context, threat intelligence, GeoIP, and hostname resolution to each flow. The result: your SIEM receives network telemetry it can actually use. Named users instead of IP addresses. Application names instead of port numbers. Threat-flagged flows instead of raw connections. And at a volume that doesn't break your ingest budget. What NFO enables: * Full network visibility inside Splunk and Microsoft Sentinel, with CIM- and ASIM-compliant output that works with existing detection rules and dashboards * Lateral movement, exfiltration, and C2 beaconing detection from network flow data * Compliance evidence for CMMC, NIST, and FISMA from user-attributed network records * Zero-touch device discovery and SNMP monitoring across your entire infrastructure estate Organizations with existing NetFlow infrastructure are typically ingesting enriched data into their SIEM in under an hour.
