With the emergence of social networking, video streaming, peer-to-peer technology, cloud computing, and software as a service (SaaS), modern enterprises are only as good as their network integrity in terms of the bandwidth and security they provide. To keep the network's bandwidth in check for everyday business communication, selecting a suitable tool to manage the NetFlow data is of utmost importance.
NetFlow is a network protocol designed by Cisco that collects and monitors IP traffic information that is generated by NetFlow-based routers or switches. These routers export traffic stats as NetFlow records.
A NetFlow collector is an application that ingests NetFlow data and organizes the binary data into a numeric format. It also:
Analyzing the required data using tools like NetFlow analyzers, network administrators can prevent malicious attacks, monitor network availability and performance, fix bandwidth bottlenecks, and analyze spikes and drops in traffic.
ManageEngine NetFlow Analyzer is a software-based NetFlow collector that collects, analyzes, and converts flow data into readable reports, and presents it on a web-based interface. Providing support to both NetFlow version 5 and version 9, NetFlow Analyzer also supports other network flows like sFlow, IPFIX, Netstream, J-Flow, and AppFlow, which are exported from routers and switches. The complete list of supported devices and flow types is available here. Apart from being a basic NetFlow collector, this is how NetFlow Analyzer excels:
Gain real-time visibility into your network traffic using NetFlow Analyzer, and discover the top conversations along with the source and destination IP details on the network in real-time. View the top applications on your network, and ensure that critical applications get maximum priority. The grouping settings in NetFlow Analyzer allows you to monitor the bandwidth usage cumulatively once a group is defined.
With meticulous reports accompanied by drill down options for more detailed data, network administrators can see how the network bandwidth is or was being used during any particular user's online session.
The forensic report gives you visibility into specific parameters such as traffic, application, source address, destination address, DSCP, etc. for any specific instance. This makes troubleshooting the root cause of any network issue or anomaly a breeze.
Detect a broad spectrum of external and internal security threats using the Advanced Security Analytics Module, a network flow-based network anomaly detection tool that helps in detecting zero-day network intrusions using the state-of-the-art Continuous Stream Mining Engine technology.
NetFlow Analyzer can identify scans targeting weak ports; classify network intrusions like DDos attacks, worms, malware, botnets, and P2P apps; and pinpoint post-attack signs like protocol anomalies and policy violations to tackle network security threats in real time.
