Network monitoring solutions for enterprises are not easy to choose. Choosing solutions for their business requires IT professionals and decision-makers to consider several factors, including security, compatibility, ease of use, and (of course) budget. Typically, enterprise-grade tech solutions are seen as expensive, but is that always the case? The answer is no! If you are selecting a network monitoring solution for your business, you should consider several free and open-source options.

Here is a compiled list of the best free and open-source network monitoring tools. You can either download and install these tools for free or they are released under an open-source license. Certainly, take them into account if you want to keep costs down, but keep in mind that they may not be the best fit for your business. A lot of open-source programs require technical knowledge or developer expertise, and many free tools are slimmed-down versions of more comprehensive monitoring programs. Thus, we’ve listed some of the main features of each free and open-source solution so you know what each one specializes in.
