Microsoft Defender External Attack Surface Management vs. Norton Small Business

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 are a small company; Norton Small Business gives us the freedom for our remote employees to work securely using their personal laptop /smartphone. Less appropriate: Someone with a few separate locations that require separate cybersecurity environment but would still benefit from centralized management.

It's good for a small business that needs cybersecurity without needing to spend a lot of money. Besides being affordable it seems to be extremely, reliable, and easy to use.

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.

We did not actively consider any other software. Overall we did do a basic understanding of a pricing & features and found that the offerings from Symantec were better than others even prima facie. At the current time for an organisation such as ours we do not believe that there is any other option worth active consideration
