Some systems you can quietly take offline at 2am for maintenance. This is not one of them. Every time someone clicks a link, opens a file, or loads a website on one of the more than a billion devices Microsoft Defender protects, a question has to be answered in milliseconds: is this safe?

Tens of billions of times a day, the cloud services behind that answer say yes, or no, and stand behind it. I'm looking for the leader who will own them. Here's what you'll own. This is the cloud brain of Microsoft Defender's real-time protection: file threat defense, URL and web reputation, network protection, and the threat-intelligence pipelines and verdict services that feed them.
