With the cloud, SaaS, remote working etc. the days of central IT/Procurement departments dictating the technology mix across the organisation is long gone.

Now employees are often bringing in new technologies and IT/Security are forced to scramble and figure out how to manage them.

It's exactly what happened with the iPhone/iPad and now increasingly Macs as well.

No, they're really not. Maybe at some startups, but large organizations have too much to lose by allowing random software to be installed instead of a single suite like microsoft provides. As new programs appear microsoft will continue to copy or buy them and absorb them into office, and will continue to get more and more dominant in the enterprise productivity game.

Most software these days has moved to Cloud or SaaS including Microsoft with Office 365.

And so whether you are running Mac, Windows or iPad simply isn't as important to IT/Security teams.

Some orgs I worked at had Mac as a standard machine. Not that Apple is in “enterprise business”, but they can sell hardware to some enterprises.
