I'm a little baffled how Qumulo could crack the Leaders' quadrant. I'd expect them to be in the Visionaries quadrant, I think. I've met with them several times. Nice people, promising product, but as of this writing, they're missing enterprise-class features, particularly for those firms with strict security, auditing and data protection requirements. I don't doubt that those features will be coming down the pike someday, but they're simply not there now. Is it possible that Gartner only considers scalability and performance? Qumulo looks pretty solid as far as those two items go.
Anyway, congrats Qumulo! That's a big deal for a relatively recent start-up!
