NetXMS – Unified Monitoring for Networks, Servers, and Everything in Between What is NetXMS NetXMS is a cross-platform, agent-based monitoring system that aims to cover it all: network devices, Windows and Linux servers, virtual machines, applications, and services. Think of it as a mix between traditional SNMP polling, active agent checks, and service monitoring — all rolled into one system with a native GUI.

Unlike tools that only do one layer well (say, network discovery but no OS metrics),

mitmproxy – When You Need to See What’s Really in the Traffic What is mitmproxy mitmproxy is an interactive, console-based HTTPS proxy that lets you inspect, modify, and debug HTTP(S) traffic on the fly. It acts as a transparent man-in-the-middle: intercepting browser traffic, API calls, mobile app requests — and showing it in real time.

It’s a favorite tool among penetration testers, backend developers, and network troubleshooters. Unlike packet-level sniffers, mitmproxy actually understands H

Unicornscan – Asynchronous Port Scanning with a Researcher’s Touch What is Unicornscan Unicornscan is a high-performance, asynchronous port scanner built with one goal in mind: collect as much network info as possible, as fast and accurately as possible. Unlike Nmap, which prioritizes depth and stealth, Unicornscan goes wide — scanning large address spaces, quickly and efficiently.

It’s used in research, red teaming, and environments where speed matters more than quiet. It doesn’t just tell you

EtherApe – Real-Time Network Visualization, the Old-School Way What is EtherApe EtherApe is a graphical network monitoring tool that maps traffic in real time. Picture a constantly updating topology map where nodes (hosts) and links (connections) change size and color depending on how much data is moving through them. That’s EtherApe.

It’s inspired by Etherman and crafted for sysadmins who prefer visual over textual. While it won’t replace a full-blown NMS, it’s ideal when you want to see what’
