CloakShare
Use Case
NDA Sharing
Share NDAs and confidential agreements securely with email verification, automatic expiry, and complete audit trails. Know exactly who accessed the document and when.
Audit trail coverage for every view of every document
Typical link expiry window for time-sensitive NDAs
Copies of the original file transmitted to the viewer (canvas rendering)
The problem
NDAs and confidential agreements demand more security than a PDF attachment. CloakShare provides email-verified access, password protection, automatic expiry, and complete audit trails. Every view is logged, every page tracked, and dynamic watermarks ensure any leak is traceable. For legal teams managing dozens of active NDAs, the API automates link creation and integrates with existing contract workflows.
Why CloakShare
Email-gated access ensures only the intended signatory can view the NDA
Complete audit trail with timestamps, IP addresses, and pages viewed
Automatic link expiry after the signing window closes
Dynamic watermarks deter unauthorized screenshots or redistribution
Password protection adds a second authentication layer
API integration automates NDA distribution from your contract management system

Documents and video in one platform
CloakShare is the only secure sharing platform that combines document and video sharing with per-viewer analytics. Upload your PDF or presentation alongside a video walkthrough. Both are tracked, watermarked, and protected with the same access controls. No other tool does this.
Frequently asked questions
Is CloakShare secure enough for confidential legal documents?
Yes. Documents are rendered server-side and displayed via canvas, so the original file is never transmitted to the viewer. Email gating, password protection, dynamic watermarks, and link expiry provide multiple layers of security.
Can I prove that a party received and reviewed the NDA?
Yes. The audit trail logs the exact timestamp, viewer email (verified), IP address, pages viewed, and time per page. Export this data via API for your legal records.
Can I automate NDA distribution?
Yes. Use the CloakShare API to programmatically create email-gated, watermarked links for each party. Integrate with your contract management or CRM system. Webhooks notify you when each party views the document.
What happens after the NDA signing deadline passes?
Set a link expiry date when creating the link. After that date, the document becomes inaccessible. No manual cleanup required. You can also manually disable a link at any time.
