Everything you need to run a secure data room

From document encryption to buyer analytics, H1 Vault gives dealmakers the tools to share confidently, track engagement, and close faster.

Document Management

Secure Document Sharing

Upload and share documents with AES-256-GCM encryption at rest and TLS in transit. Every file is encrypted before it reaches storage, and decrypted only when an authorized user requests it.

  • AES-256-GCM encryption at rest for all uploaded files
  • TLS 1.2+ encryption for all data in transit
  • Secure download links with expiration controls
  • In-browser document viewer with no local caching

Folder Organization

Organize documents into nested folder hierarchies. Use industry-standard templates for M&A, fundraising, or real estate deals to get started in seconds.

  • Unlimited nested folder structures
  • Drag-and-drop document and folder management
  • Industry templates for M&A, fundraising, and real estate
  • Custom folder creation for any deal structure

Bulk Operations

Upload entire folder structures via ZIP, download multiple documents at once, and manage permissions in batch. Save hours of manual work on large data rooms.

  • ZIP upload with automatic folder structure preservation
  • Bulk download of selected documents or entire data rooms
  • Batch permission updates across documents and folders
  • Folder templates for rapid data room setup

Document Versioning

Upload new versions of documents while keeping the full history. Buyers always see the latest version, and you maintain a complete audit trail of changes.

  • Upload replacement versions for any document
  • Full version history with timestamps
  • Automatic notification of updated documents
  • Previous versions accessible for compliance

Access & Security

Granular Access Controls

Control exactly who sees what at the document and folder level. Create buyer groups, assign permissions per group, and manage staged disclosure throughout the deal lifecycle.

  • Document-level and folder-level permissions
  • Buyer groups for organized access management
  • View, download, and print permission controls
  • Instant access revocation by disabling share links

Phase-Based Disclosure

Release documents in stages as the deal progresses. Control which buyer groups can see which documents at each phase, from initial review through final due diligence.

  • Create multiple disclosure phases per data room
  • Assign documents and folders to specific phases
  • Activate phases on your schedule
  • Buyer groups see only their authorized phases

Passwordless Authentication

Magic links for admins, email verification codes for buyers. No passwords stored, no credential databases to breach, no password reset flows to manage.

  • Magic link login for admin users
  • 6-digit verification codes for buyer access
  • Tokens expire after 15 minutes (magic links) or 10 minutes (codes)
  • Rate-limited to prevent brute force attacks

Dynamic Watermarks

Automatically overlay watermarks on viewed documents with the viewer's email, access time, and IP address. Deter unauthorized sharing and trace document leaks.

  • Automatic watermarking with viewer identity
  • Includes email, timestamp, and IP address
  • Applied to in-browser document viewing
  • Configurable per data room

Analytics & Insights

Real-Time Buyer Analytics

See who's in your data room right now and what they're looking at. Track engagement across buyers and documents to understand deal momentum and prioritize follow-ups.

  • Live activity feed showing buyer actions
  • Per-buyer engagement scores and time spent
  • Document-level view counts and duration metrics
  • Identify most and least reviewed documents

Page-Level Document Tracking

Go beyond document-level analytics. See which specific pages of a document each buyer viewed, how long they spent on each page, and what they skipped.

  • Per-page view tracking for multi-page documents
  • Time-spent metrics per page per buyer
  • Heatmap of most-viewed pages
  • Understand exactly what buyers focus on

Comprehensive Audit Trail

Every action in your data room is logged with timestamps, user identity, and IP address. Export audit logs for compliance reviews, legal proceedings, or internal records.

  • Full event log: views, downloads, uploads, permission changes
  • Timestamps and IP addresses for every action
  • Exportable audit reports for compliance
  • Filterable by user, document, or action type

Collaboration

Q&A Workflow

Manage buyer questions in a structured workflow. Buyers submit questions from within the data room, you assign them to team members, and answers are posted with a full audit trail.

  • Buyers submit questions from the data room interface
  • Assign questions to specific team members
  • Track question status: pending, in progress, answered
  • Full audit trail of all Q&A activity
