You're probably using a ton of different cloud solutions: one for email, another for audio conferencing, a third for your firewall etc... it's hard to to keep track of all the different accounts you have, how much you're paying for all of them, and they don't all integrate together. It's hard to work securely and productively when you're using so many services, that's why we recommend consolidating as much as you can to Office 365 and Azure, because they do nearly everything!
