My program includes a file uploading feature which is more trustable to make use of other online file hosts. Who are able to recommend 1 secure file hosting service that may provide API that may be easily integrated like Paypal.

If my program isn't that safe and that we don't have any time for you to fix all of the security bugs and that we donot care, but we would like the files the customers submitted to become absolutely safe. Is the fact that smart to seperate this file uploading part from the unsecure program and also have it running on another server? Even better, produce other people to bother with security while on an file uploading service? Anybody has any experience or applying for grants this?
