I use notes and notability, each of which syncs using icloud. I also use the feature (I don't know the name) of the shared clipboard which also I think uses icloud for authentication.

Finally, if I, say, download a PDF from my computer, I can open it from the ipad because my downloads folder is in iCloud. This one, at least, you could use use if your company permits a different cloud provider.
