AWS CloudTrail vs. Microsoft Defender External Attack Surface Management

It is necessary to enable [AWS] Cloudtrail when using AWS in a production environment, otherwise you will not have any idea what is happening within your accounts. Third party monitoring applications will all require [AWS] CloudTrail to be enabled as well. I would not recommend it solely as a monitoring tool, to get the most out of it you must send the logs elsewhere. Either to Cloudwatch logs or a third party product.

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.

We rate Microsoft Defender External Attack Surface Management’s overall usability as 10 out of 10 because it delivers a strong balance between depth of capability and ease of use, particularly within organizations already operating in the Microsoft security ecosystem.

I think in the end, CloudTrail has more features and you can dive deeper inside the logs so it depends on your usage and what you expect in the end to make the right choice, I would say that both tools are really useful and bring a lot of benefits to I.T. companies.

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.
