Where do we go from Google?

Now that Google has cut off unlimited storage, what are the alternatives?
I was paying 20 dollars a month for unlimited
Any options like this?

@aivit either Box or dropbox Business Plan provided needs to encrypted

I have a MS Ondrive Business Plan 2 , with 5 License (storage unlimited) only two License i have used 3 are remaining

Initial it will 5 TB once the storage reached 90% then 25TB , after 25 TB storage will be provided on sharepoint. Storage will be increased accordingly.
