Problem
Dealmakers, founders, and finance teams managing confidential transactions rely on disjointed or insecure document-sharing tools that lack granular access control, compliance features, and visibility into viewer activity. This creates risks of unauthorized access, data leakage, and a lack of accountability during critical processes like M&A, fundraising, and due diligence.
Solution
Papermark provides a virtual data room and secure document-sharing platform designed to host confidential documents while maintaining strict control and insight. The platform enables teams to share documents with granular permissions, require NDA acceptance, apply dynamic watermarks, and track page-by-page viewer activity for complete oversight. Papermark offers both a cloud SaaS deployment and an open-source, self-hosted option, ensuring flexibility for organizations with specific security and regulatory requirements. With a focus on compliance, the platform automates audit trails and integrates enterprise-grade controls such as SSO, IP allow-listing, and end-to-end encryption.
