    Microsoft
    Microsoft Defender External Attack Surface Management is particularly well-suited for discovering, inventorying, and continuously monitoring the external attack surface, especially in environments with heavy Microsoft adoption. It is less suitable as a standalone solution for internal scanning, real-time attack detection, automated remediation, or advanced application testing. Microsoft Defender External Attack Surface Management es especialmente adecuado para descubrir, inventariar y monitorear continuamente la superficie de ataque externa, sobre todo en entornos con fuerte adopción de Microsoft. Es menos adecuado como solución única para escaneo interno, detección de ataques en tiempo real, remediación automática o pruebas avanzadas de aplicaciones.

    Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
    As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
    Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.

    • Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
    • Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.

    We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.

    The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.

    I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.

    Because Microsoft Defender External Attack Surface Management is part of the broader Microsoft Defender family (including Defender XDR, Entra ID, Azure Security, Sentinel, etc.), it:
    Shares identity, endpoint, and threat context across tools
    Reduces the need for custom integrations or connectors
    Works in a “single pane of glass” experience for SOC analysts
    Why it matters:
    Organizations already invested in Microsoft security tools gain greater contextual insight and lower operational overhead.

    Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].

    • With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free.
    • You can set up as many alerts as you want without incurring any fees.
