Secure Document Sharing for Legal

Legal documents require careful handling. Whether you are sharing contracts for review, distributing NDAs to counterparties, or managing due diligence materials, the standard email attachment creates uncontrolled copies that can be forwarded, stored, and accessed indefinitely.

LinkVault provides a controlled viewing experience. Recipients open documents in a secure browser viewer with the access rules you set: password, expiration, approval, OTP verification, and watermarking.

Email OTP Verification

Require recipients to verify their identity via a one-time code sent to their email before viewing. This ensures only the intended recipient can access the document.

Password Protection

Add a password layer so that even if a link is forwarded, the document cannot be opened without the password.

Expiration & View Limits

Set documents to expire after a review period or after a specific number of views. This prevents old versions from remaining accessible indefinitely.

Approval Workflows

Require your explicit approval before any visitor can view a document. You review the access request and decide whether to grant access.

Dynamic Watermarking

Overlay contextual information across the document to deter screenshots and create accountability for any captured content.

• Contract review with opposing counsel — expiring, password-protected links
• NDA distribution to candidates — OTP-verified access with watermarks
• Board materials — approval-gated, time-limited viewing
• Due diligence data rooms — multi-document rooms with access controls
• Client deliverables — paid delivery gated behind Stripe

LinkVault is designed to reduce the risk of unauthorized access and distribution. However, any content rendered in a browser can theoretically be captured by a determined viewer. We believe in being transparent about this limitation rather than making impossible promises.

Our approach is to add enough friction and traceability that casual misuse becomes impractical and accountable.
