Microsoft Defender External Attack Surface Management vs. TeamViewer

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.

Helpful for organized IT teams supporting multiple manufacturing warehouse zones. Useful for training, auditing, and meeting ISO/quality or compliance documentation requirements. False positives can lock users out unexpectedly, particularly common when supporting remote home users. Session connections can be interrupted, which is painful when configuring warehouse automation systems and printers that require a restart.

• Now, it doesn’t work in fast network environments: sometimes, data is delayed during transfer.
• There are a small number of ways that a user is allowed to change the interface on the device.
• Some minor increases in difficulty with advanced functions of the application.

As long as I continue to provide remote support for my clients, it's a no brainier. For what I pay out, I probably make it back tenfold in the ability to provide remote support from wherever and whenever. Not to mention the saved gas money for a fix that only takes 5 minutes but it takes you 20 minutes to get there. As my business continues to grow, and I support more and more clients, my need for TeamViewer will only grow.

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.

Compared to other products I've used (ConnectWise Control), TeamViewer is harder to set up and get connected. It is especially difficult to set up "permanent" unattended remote access, where you want to be able to connect to and control a remote computer without having to exchange codes and passwords every time you connect.

We get what we need with our TeamViewer licence.

The support from the Teamviewer team has always been top notch. Any support ticket that we have submitted has been handled very quickly and with the best possible resolution. We find in most cases, contacting for a support ticket is not even necessary, as the knowledge base is more than adequate.

As expected without any problem! Alternate in-person training is another efficient way to learn how a product works. There are many third party supporters for TeamViewer courses available that can give additional ideas how to use TeamViewer for specific functions and features as we did require in respect of our usage.

I have never used the online training either. I have watched a few informational videos that were helpful when learning how to do a specific procedure within TeamViewer and get the most out of the software by utilizing one of the many features that are available with the software. Again, 5 if for neutral.

TeamViewer installation and deployment to other devices is pretty straightforward and does not require much technical know-how. This makes ease of use attractive when supporting both new and existing clients with limited technical knowledge. I think ease of use is a huge factor in getting new clients. TeamViewer handles that extremely well.

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.

Apple Remote Desktop requires a VPN connection to the LAN to be useful, but it is still necessary to use it when TeamViewer will not connect. Datto RMM seems very solid, and I like it, though I only have access to it from our MPS. It can often connect when the TV cannot. ScreenConnect was not a good fit for us and did not seem to work well.

I've rarely had problems with the product.

• Remotely accessing devices in our office allows employees to stay productive while working from home.
• TeamViewer helps us to collaborate with other firms for projects we're doing.
