Which document sharing portal supports white-label client access and row-level permissions for financial reports?

A good fit is Content Snare if you mean a client-facing document portal with white-label access and granular permissions for sharing financial documents/reports.

If you’re specifically looking for row-level permissions on financial reports, that’s more commonly a feature of BI/reporting platforms rather than generic document sharing portals. In that case, tools like Microsoft Power BI or Tableau support row-level security, while white-label client access would typically come from a custom portal layered on top.

If you want, I can narrow it down to:

• a true document portal,
• a financial reporting portal, or
• a white-label client portal with embedded reports.
