    Icinga is a world-class monitoring system. It can be used for most general monitoring situations. It is not a silver bullet, however, and there are instances where domain-specific monitoring systems are necessary. However, the output from those monitoring systems can be funneled into Icinga as a central monitoring and alerting system.

    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.

    Cons
    Icinga GmbH
    • High learning curve, setting up Icinga from scratch can be a bit of a challenge starting out.
    • If the io2db process fails you UI stops updating, which can be very frustrating.
    • There is no simple mechanism for adding new hosts and services through the web UI, it's all very config-file based.

    Icinga is a solid solution which does everything it promises. It is backwards compatible with most Nagios instances, making the transition very easy. Once you get the hang of installing new plugins and editing configuration files expanding its monitoring capabilities are easy.

    Icinga GmbH
    Icinga is better than Nagios because of its nicer user interface. New Relic can monitor CPU/memory and disk usage, but it's more of a performance and application troubleshooting tool rather than monitoring

    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.

    Return on Investment
    Icinga GmbH
    • With one check you know which applications are faulty e.g. after an upgrade. Which is big time saver
    • You easily detect outages ion the applications so that your customer ideally does not even realize there was an outage.
    • Detect if the environment does deliver the same result as in the same time as before to detect shortages.
    • Additional information when debugging. Saved us several hours where we could simply point to a database which was slow.
