Microsoft today announced that it is bringing its Microsoft Defender Advanced Threat Protection (ATP) to the Mac. Previously, this was a Windows solution for protecting the machines of Microsoft 365 subscribers and assets of the IT admins that try to keep them safe. It was also previously called Windows Defender ATP, but given that it is now on the Mac, too, Microsoft decided to drop the “Windows Defender” moniker in favor or “Microsoft Defender.”

“For us, it’s all about experiences that follow the person and help the individual be more productive,” Jared Spataro, Microsoft’s corporate VP for Office and Windows, told me. “Just like we did with Office back in the day — that was a big move for us to move it off of Windows-only — but it was absolutely the right thing. So that’s where we’re headed.”

He stressed that this means that Microsoft is moving off its “Windows-centric approach to life.” He likened it to bringing the Office apps to the iPad and Android. “We’re just headed in that same direction of saying that it’s our intent that we can secure every endpoint so that this Microsoft 365 experience is not just Windows-centric,” Spataro said. Indeed, he argued that the news here isn’t even so much the launch of this service for the Mac but that Microsoft is reorienting the way it thinks about how it can deliver value for Microsoft 365 clients.

Given that Microsoft Defender is part of the Microsoft 365 package, you may wonder why those users would even care about the Mac, but there are plenty of enterprises that use a mix of Windows machines and Mac, and which provide all of their employees with Office already. Having a security solution that spans both systems can greatly reduce complexity for IT departments — and keeping up with security vulnerabilities on one system is hard enough to begin with.

In addition to the launch of the Mac version of Microsoft Defender ATP, the company also today announced the launch of new threat and vulnerability management capabilities for the service. Over the last few months, Microsoft had already launched a number of new features that help businesses proactively monitor and identify security threats.

“What we’re hearing from customers now is that the landscape is getting increasingly sophisticated, the volume of alerts that we’re starting to get is pretty overwhelming,” Spataro said. “We really don’t have the budget to hire the thousands of people required to sort through all this and figure out what to do.”

So with this new tool, Microsoft uses its machine learning smarts to prioritize threads and present them to its customers for remediation.

To Spataro, these announcements come down to the fact that Microsoft is slowly morphing into more of a security company than ever before. “I think we’ve made a lot more progress than people realize,” he said. “And it’s been driven by the market.” He noted that its customers have long asked Microsoft to help them protect their endpoints. Now, he argues, customers have realized that Microsoft is moving to this person-centric approach (instead of a Windows-centric one) and that the company may now be able to help them protect large parts of their systems. At the same time, Microsoft realized that it could use all of the billions of signals it gets from its users to better help its customers proactively.
