Introduction

NetFlow Optimizer™ (NFO) is a high-performance, software-only processing engine that transforms massive streams of raw network data into high-fidelity, actionable intelligence — before it reaches your SIEM, IT operations platform, or data lake.

NFO acts as a vendor-agnostic pre-processor. It ingests data from physical, virtual, and cloud environments, reduces volume, enriches records with business context, and delivers a clean, optimized stream to your downstream systems in real time.

NFO Architecture Overview

What NFO Does​

NetFlow Optimizer provides a 360-degree view of your network by unifying two critical data streams:

  • Flow Optimization & Enrichment: NFO accepts NetFlow, IPFIX, sFlow, and J-Flow from network hardware, alongside Cloud Flow Logs from AWS, Azure, OCI, and Google VPC. It deduplicates, aggregates, and enriches these records so your SIEM receives only high-value, context-rich data.
  • Infrastructure Metrics: NFO actively polls devices via SNMP and Model-Driven Telemetry (MDT) for performance metrics, and receives SNMP Traps for immediate event notification.

Core Capabilities​

Volume Reduction​

Modern networks generate a "NetFlow Tsunami" that can overwhelm SIEM storage and inflate licensing costs. NFO intelligently reduces data volume by 80–90% without sacrificing the visibility required for security and compliance.

  • Intelligent Aggregation: Summarizes similar flows and optionally excludes ephemeral client ports, collapsing hundreds of micro-flows into a single high-value record.
  • Deduplication: Identifies and removes redundant flow records caused by overlapping collection points, ensuring only unique information is forwarded.
  • Flow Stitching: Reconstructs unidirectional flows into complete bidirectional conversations, providing a 360-degree view of interactions while reducing record counts by an additional 50%.
  • Top N Analysis: Automatically surfaces the most impactful traffic patterns — top talkers, heaviest bandwidth consumers, and most-used applications.

Context Enrichment​

Raw IP addresses are "naked" data — they show how much, but not who or why. NFO transforms connection records into rich, context-aware intelligence ready for security analysis and AI/ML pipelines.

  • User Identity: Links traffic to specific users via Active Directory, Okta, and Microsoft Entra ID.
  • Threat Intelligence: Automatically flags communications with known malicious actors using real-time threat reputation feeds.
  • GeoIP & Location: Maps every flow to a physical location, country, and ASN using industry-standard geolocation databases.
  • Cloud & VM Context: Correlates flows with VM names and cloud instance metadata (AWS/Azure/GCP/OCI) to simplify investigations in hybrid environments.

Investment Leveraging​

NFO is designed to extend and maximize the tools you already have — not replace them.

  • Native SIEM Integration: Streams enriched data directly into Splunk, Microsoft Sentinel, CrowdStrike, Sumo Logic, Exabeam, and more.
  • IT Ops & Observability: Feeds DataDog, New Relic, Elastic, and other monitoring platforms with the same optimized stream.
  • Data Lakes & Streaming: Delivers to Kafka, Amazon S3, Azure Monitor, ClickHouse, and OpenSearch for long-term retention and analytics.
  • Cost Management: By reducing volume before data reaches downstream platforms, NFO dramatically lowers ingestion and storage costs — allowing you to monitor more network for the same budget.

Multi-Group Infrastructure Insights​

Traditional SNMP monitoring requires manual configuration for every new device, leading to visibility gaps and configuration drift. NFO's Multi-Group Inheritance model automates infrastructure classification from day one.

  • Zero-Touch Discovery: As new hardware is added, NFO automatically detects vendor, role, and feature set — no manual templates required.
  • Hierarchical Inheritance: Devices inherit monitoring profiles based on their position in the infrastructure hierarchy. A switch identified as "Cisco + Core + Layer 3" instantly receives the correct polling intervals and OID maps.
  • Contextual Health Mapping: Role-specific metrics ensure that a congested interface on a backbone trunk is prioritized differently than one on a standard access port.
  • Dynamic Inventory Tracking: Maintains a real-time, self-updating inventory of your entire estate, continuously auditing software versions and device features to simplify compliance reporting.
