Microsoft Defender ATP Security Platform Coming to iOS and Android

Microsoft Defender is great on Windows; it's nice to finally have good malware protection on Windows without having to download third party antimalware software.

However, I don't really see the point of this on MacOS. Macs already have a malicious software detection system, and so far it's done its job pretty admirably. I suppose Defender could help find Windows malware being downloaded to a Mac before it ends up on someone's other computer or Windows VM, but that seems like a limited usage scenario.

Regardless, though, having more options is great. Bring it on!

Ideal tool to reduce battery, randomly cause CPU to overclock and fans to spin up to maximum.

It’s built on the same engine which ESET uses; and I’m already using that on my Mac.

Are you finding it doing anything useful?

Yeah - and because it's all done on MS backend your complete network traffic - browser URLs your opening etc. - is logged on their backend (again: true for MS Defender ATP).
And your IT admins have a nice dashboard on i.e. https://securitycenter.windows.com/ where they "check"/see what your doing (which websites your opening, when and from where) on your device.
So from a privacy point of view - that's Orwellian total surveillance...

Which is extremely valuable when you need to backtrack what was stolen, where it was moved, which other systems were impacted and what residual RAT/malware/persistence needs to be cleaned out afterwards during a breach?

Sure, if you think of your employees as threats, rather than human beings deserving of privacy.

ANY sane IT-admin or infosec responsible sees all users of corporate resources as potential targets for intentional or unintentional compromise and data leak. The higher privilege the more counter measures and monitoring.

Identity, information and device based posture in that order.
