This particular program uses NetFlow data and analysis in an attempt to attempt to detect and, more importantly, stop DDoS style attacks on networks.

It's just about as barebones as you can get, running with a simple terminal interface that basically just grabs NetFlow data and parses it into the most basic humanly-readable format that it can manage!įlow-tools, often paired with FlowViewer which is pictured above, is another pretty straightforward and simple open-source NetFlow analysis program.Ĭoupled with FlowViewer, another open-source offering that works specifically with Flow-tools, it becomes another web-interface based option for easy perusal and visualization of NetFlow statistics.īPFT is more of an add-on than its own standalone offering – it adds onto the libpcap library and uses, as the name implies, the Berkeley Packet Filter, BPF, mechanism for capturing IP traffic to perform NetFlow analysis.ĪnonTool is a curious software which takes NetFlow analysis and management in a slightly different direction, with a focus primarily on anonymization, or deanonymization, of NetFlow traffic and the subsequent analysis of that data thereafter.Įxtremely niche but also a curious option for those invested in security and data obfuscation.Īnother open-source project for which development has tapered off but still a useful one for some needs. “Extreme Happy NetFlow Tool,” or EHNT, despite its rather quirky name is a simple and solid offering.

NTop is somewhat unique in that the interface is purely web based and makes it a lot easier to navigate and manipulate via several client machines and, what's more, there's even a github variant for Mac OSX support! NTop is a particularly common choice as one of the more well-known open-source offerings for NetFlow collection and analysis. It even includes support for Cisco-specific NetFlow features and sFlow as well! Ntop is a solid choice that works well in both UNIX environments as well as Windows.

It also has some modularity with a variety of other packages that can be used to modify what it can do and how to display data.

It's a fairly barebones piece of software, but it does precisely what it needs to do. While Cflowd is no longer under active support and updates, it's still a pretty reliable offering that does all the basic collection, storage, and analysis of NetFlow data. Most native to the GNU/Linux environment and requires a combo of collector and Perl script for the visual aspects, as well as a database component. By its very nature there's a slight delay, but it does an excellent job gathering up and displaying the NetFlow statistics for you to admire visually almost on the fly! Flowscanįlowscan is somewhat interesting in that it acts more as a generalized tool for visualizing NetFlow data rather than collecting and aggregating it for later analysis. Here's the Best Free Open Source Netflow Analyzers & Collectors of 2022: 1. If none of the solutions from below work, consider a commercially available Netflow Collector/Analyzer – some of which are free to use or have extensive Trials. Open-source software in the NetFlow realm can be powerful indeed, but you have to be sure the solution you're looking at fits your networks needs and won't leave you wanting. Projects that go untouched or end up more or less “finished” tend to taper off as far as forwards-thinking support and features, and can often fall behind the curve of normalcy if they become too deprecated, often in favor for different open-source options that are newer or built on a more current framework. With that said, however, an open-source project is only as powerful and prodigious as its proponents. Open-source software tends to have a remarkable flexibility, either via child builds and projects that spawned off the shortcomings of their forefathers, or by means of exceptional modularity and transparency that would be simply unheard of with any kind of proper, paid enterprise level solution.

When it comes to almost any software need these days there tend to be a wide range of options, both paid and free, and the open-source movement remains quite active indeed. There are a variety of tools which can assess traffic on a basic level in terms of round-time, packet loss, and other things like that, but NetFlow allows you to discern so much more about each individual packet and, what's more, levy that knowledge by means of analytic software and data aggregation via charts and graphs to dramatically ease your task at hand. NetFlow analysis is undeniably powerful when it comes to assessing and analyzing your network, network traffic and bandwidth, devices, or just about anything to do with the data being transmitted over your network.
