I'm not working in the field, so I don't really have an idea on how the attitude in banking is towards cloud integration. I wonder: What is, from a banks perspective, the responsible solution here? An older MS Office or current MS Office without network connectivity? LibreOffice? I'm a huge fan of the suite, but, for example, Libres Excel isn't really comparable to MS Excel.
