Important questions to ask

Before deciding, ask:

1. Do partners need view-only, edit, or upload-only access?
2. Do you need expiration dates and password protection on links?
3. How important are audit logs and policy enforcement?
4. Will partners be outside your organization long-term?
5. Do you need to manage lots of shared projects with different permission models?

• If your partners just need quick, easy access to files → Dropbox Business
