NetFlow data is essential for enhancing network security and streamlining IT operations. It provides a detailed view of network traffic, enabling organizations to proactively detect security threats, monitor user activity, and gather valuable insights for effective network management and optimization. With comprehensive visibility into network traffic patterns, NetFlow data empowers security teams and IT operations to maintain a robust and secure network environment while boosting the overall performance and efficiency of the network infrastructure.

NetFlow Optimizer efficiently processes large volumes of diverse NetFlow data, including IPFIX, JFlow, sFlow, and Cloud Flow Logs from Amazon Web Services (AWS), Microsoft Azure, Oracle Cloud (OCI), and Google Cloud Platform (GCP). It ensures real-time optimization and enrichment, delivering data exactly where it’s needed, in the right formats.

Additionally, NetFlow Optimizer supports SNMP Polling and SNMP Traps, further enhancing its capabilities for comprehensive network monitoring. Whether focused on network security, IT operations, or both, NetFlow Optimizer provides the tools and insights needed to keep your network secure, efficient, and well-managed.


Data Volume Reduction

Data Volume Reduction (DVR) minimizes the amount of data that needs to be stored and processed through consolidation, deduplication, or filtering.

  • Consolidation: Combines multiple data records into a single record. Bytes and packets from communicating peers are aggregated over a short configurable period by source, destination, protocol, and ports. This reduces data storage needs without losing accuracy.
  • Deduplication: Ensures each flow is reported only once, even if it passes through multiple network devices, further reducing data volume without compromising accuracy.
  • Top Traffic: Reports only the top N consolidated flows, significantly reducing data storage while maintaining high accuracy.


Flow Data Enrichment

NetFlow records contain limited information about network traffic. Flow data enrichment adds additional details to NetFlow records, such as:

  • DNS names: Domain names of the hosts involved in the flow.
  • VM names: Names of the virtual machines involved in the flow.
  • Applications: Names of the applications being used.
  • User identity: Identities of the users using the applications.
  • Cloud instance names, services, regions: Details of the cloud instances involved in the flow.
  • SNMP polling data: Data collected from network devices using SNMP.
  • GeoIP: Geographic locations of the hosts involved in the flow.
  • Reputation based on threat lists: Reputation of the hosts involved in the flow, based on threat lists.


Flow Stitching

Flow stitching consolidates client-server request-reply flows into a single flow record, offering several benefits:

  • Enhanced accuracy in traffic analysis: Provides a comprehensive view of traffic between two hosts, aiding in the identification of malicious activities such as port scans or denial-of-service attacks, improving overall threat detection.
  • Heightened visibility into network behavior: Offers a deeper understanding of how applications utilize the network, valuable for troubleshooting performance issues and identifying potential security vulnerabilities.
  • Streamlined security operations: Automates tasks involved in security operations, allowing security analysts to focus on more intricate and critical responsibilities, enhancing overall operational efficiency.


By leveraging flow stitching, organizations can optimize traffic analysis, gain insights into network behavior, and streamline their security operations, resulting in improved network performance, enhanced security posture, and more efficient resource utilization.
