Microsoft Teams is on fire! We’re the hottest v1 product at Microsoft and even before we launched the press was calling us “the first product to truly compete against hot group-messaging apps” (PC World), and Gartner called us “a real game changer”. We have audacious goals as we build on our first six months and momentum from Ignite.

Security is a top customer concern for adopting Microsoft Teams. Microsoft is betting heavily on Microsoft Teams but will not be able to succeed unless it meets customer security needs.
