One workspace. Every surface.
Polybase ships DocSend-style sharing as part of the workspace: create a share link, and recipients open the document in a page-by-page viewer. You see who viewed which page and for how long, can require an email before viewing, and manage every link from one dashboard. The difference is that the documents themselves live in the same workspace as your team's chat, tasks, docs and calls — and the whole thing can run on EU cloud, in your VPC, or fully air-gapped on your servers.
