Secure Document Sharing & Virtual Data Room Features
Virtual data room features built for secure document sharing: high-fidelity viewing, link controls, and privacy-first analytics.
Virtual data room features that keep control after you share
Use DocKosha for investor updates, due diligence, sales collateral, and internal sharing with stronger controls and a faster viewer than typical file-sharing tools.
Security that fits real workflows
Protect documents with encryption, dynamic watermarking, and VDR-grade permissions designed for everyday sharing and high-stakes rooms.
High‑fidelity viewer
Share PDFs and processed assets powered by DocYantra, our proprietary rendering stack that keeps fidelity pixel-perfect on mobile and desktop.
Engagement you can act on
See what people read with time-per-page, downloads, and engagement events, anonymized by default. Viewer-level identity appears only when you enable gates like Email Verification, NDA, or Allowlists.
Viewer commenting (verified)
Collect feedback in context with threaded comments pinned to highlighted text. Commenting requires verification, so conversations stay tied to real viewers.
Document versioning
Replace files without breaking links. Keep version history with retention controls, preview, and one-click restore from the internal viewer.
Virtual data rooms
Organize folders for due diligence and fundraising, then control access with link settings, expirations, gates like NDA and email verification, and granular allow rules down to folders and documents (including user groups).
Analytics that answer real questions
Track views, time per page, downloads, and engagement to understand what is landing. Export viewer insights to CSV when you need reporting (email when collected; otherwise pseudonymous viewer IDs).
Link-level controls
Customize each link: require verification, set allowlists/blocklists (emails + user groups), apply presets, set expirations, limit downloads, and enforce viewer rules—plus advanced access control inside data rooms.
Custom URLs
Create clean, memorable share links with custom URL paths. Uniqueness is enforced within each workspace, so different teams can use the same path without cross-workspace conflicts.
Secure PDF redaction
Permanently remove sensitive information from PDFs (and converted documents). Save as a new file or replace the current version while preserving links and version history.
Audit trails
Keep an owner-only audit log of key activity like uploads, deletes, renames, link changes, and access grants/revokes across documents and data rooms.

Video walkthroughs now live in a dedicated demos section, separate from feature documentation.

Privacy-First Document Analytics
Get useful insights without over-collecting. Analytics are anonymized by default and designed to avoid storing unnecessary PII.
- • Anonymized by default; viewer email is collected only when link settings require it
- • No raw IP storage; country is derived transiently
- • Email collection occurs only when explicit link settings (like Email Verification, NDA, or Allowlists/Blocklists) require it
- • CSV export is available for document viewer insights; broader exports (data rooms/workspace) are coming soon
