Microsoft Defender External Attack Surface Management vs. Microsoft Defender for Cloud

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.

Microsoft Defender for Cloud is very good at allowing users to see how their Azure environment is secure through the secure score. The recommendations are an excellent source of the controls that should be in place to ensure a secure environment. There needs to be more protection and features for data security.

• Lack of visibility of external assets
• Reduction of the risk of external attacks
• Falta de visibilidad de activos externos

• Automation is crucial to managing sprawl and the additional complexity that comes with it. SOC management workbooks and process automation give significant flexibility.
• The Security posture score and Security Alerts are neatly centralized and offer me crucial information quickly.
• Defender for Cloud avoids the common compromise of simplicity for completeness (former Azure Security Center). The security warnings and advice go into great detail while remaining current and useful.

Incentivized

• Asset Attribution and Ownership Clarity
• Risk Prioritization and Business Context
• Noise and False Positives

• UI/UX. It can get a little messy when navigating around with all the flyouts in the Azure portal which can be frustrating, particularly when under time pressure.
• The query languages for the queries and workbooks are another language that needs to be learned - it would be nice to have kept it closer to T-SQL or something like that to minimize the need to learn new syntax.
• Adding cost estimations to the security recommendations would really improve the experience.

It is a great product that integrates nicely when running an Azure platform and even multi-cloud environment. Not looking for point-solutions but a suite that answers most requirements. It is very comfortable being able to use KQL, workbooks and automation that is native to the azure platform

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.

My visibility is limited because I'm only doing very small pieces of what the overall org does. And also, we have limitations on what we're allowed to use. It's not like we get a new product as users or leadership level users, and everything is on, and we can just do whatever we want. We're very restricted in what we can use any tooling within the org because of the different levels of regulatory constraints we have, because of just the nature of who we are inherently. So that's why. I don't think it's necessarily the product. I think it's more or less of what we're able to do with the product.

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.

Barracuda goes neck to neck with Microsoft Defender for Cloud in the anti-spam, anti-phishing email suite. But why I chose this product is because again, it's very well embedded with Microsoft technology, and we're a Microsoft shop, and it works well for us to use that product and have better visibility versus Barracuda being just an offshore, just a single product versus Microsoft Defender for Cloud being blended with other applications.
