ManageEngine NetFlow Analyzer - 2026 Pricing, Features, Reviews & Alternatives

NetFlow Analyzer is a holistic network bandwidth monitoring and traffic analysis solution developed specifically to address performance issues of today's dynamic IT infrastructures. NetFlow Analyzer promotes visibility into hybrid and cloud networks and provides insights into bandwidth usage of every element, down to applications and users. With deeper analytics into traffic by volume, speed and utilization, network admins can evaluate the quality and reliability of the network and troubleshoot performance bottlenecks before they impact users. It offers the following benefits:

- Multi-vendor support: NetFlow Analyzer supports multiple flow technologies like NetFlow, sFlow, J-Flow, IPFIX, etc. Admins can monitor the bandwidth usage of a wide range of devices and find out the root cause of issues that have been influencing productivity. Enterprises can also discover the non-flow exporting devices and monitor their traffic with the new agent, Network Packet Sensor.

- Application usage monitoring: Enterprises can monitor app-specific traffic by how each application is being used in your network and by whom with deep visibility into Layer 4 and Layer 7 applications. IT admins can also map homegrown applications or integrate with ManageEngine Applications Manager to monitor other application services traffic.

- Traffic shaping: Maintaining the streamlined performance of top business-critical applications can be a challenging task for admins. NetFlow Analyzer comes in handy, as they can apply QoS policies to different applications or links and evaluate the effectiveness of such policies with CBQoS, which shows the pre-policy and post-policy traffic trends.

- Anomaly detection: With network behavior anomaly detection (NBAD), organizations can detect any unusual traffic behavior in their network, and get notified when there are suspicious IP addresses or traffic enters the network. Besides the existing algorithms and thresholds, admins can also configure new ones based on encountered attacks to notify before it crashes the network.

- Wireless network traffic monitoring: NetFlow Analyzer provides information on wireless controllers and their real-time traffic. Along with this, organizations can monitor the number of users accessing their wireless network by individual access points, SSIDs, Client IP addresses, and MAC addresses. With such detailed insights, organizations can find how their bandwidth is being used and if there are any rogue devices intruding into the network.

- IPSLA monitoring: IT admins can monitor the VoIP, video and WAN traffic to align it with SLAs and prioritize their client's experience. NetFlow Analyzer provides critical metrics such as jitter, packet loss, and MOS, where they can also edit the threshold details and get alerted on any event where the threshold exceeds.

- Threshold-based alerts: With different alert categories such as real-time, aggregated, and security, admins can establish a baseline behavior and configure alert profiles with criteria and severity. When the performance or traffic behavior goes above or below or is abnormal, NetFlow Analyzer alerts the admins via the notification mode they choose.

- Network forensics: Root cause analysis of a network issue can be cumbersome and unfruitful. NetFlow Analyzer's forensics report offers in-depth information with raw data-based reporting. Admins can have a look into the network's past traffic behavior and find any underlying issues with metrics such as TCP flags, Next Hop, Packet Loss, and so on.

- Capacity planning: NetFlow Analyzer's capacity planning reports can help forecast bandwidth usage of organizations to help better plan their network upgradation with visibility into how the utilization has been changing for applications and the overall network.

- Alerts for downtime: As a proactive bandwidth monitoring tool, NetFlow Analyzer notifies the admins when the traffic limits are reduced or exceeded for a particular interface, application, or device.
