For secure sharing
Share proof without oversharing
Share only the items you choose, with an expiry, an optional access code, and a full activity log — and revoke access whenever you want.
The problem
Sharing a document by email or a public link exposes more than you intended, and you can't take it back once it's out.
How CertaNest helps

- 5Revoke access anytime
Features you'll use

Private until shared. Revoked and expired links are blocked server-side, not just hidden.
Frequently asked questions
Can I take back access after sharing?
Yes. Revoke a share at any time, and expiring links close automatically. Both are enforced on the server, not just hidden in the UI.
Does the recipient see my whole vault?
No. A share exposes only the specific items you select. Everything else stays private.
Is the storage secure?
Files are encrypted at rest and private by default. We describe our protections plainly, without exaggerated security claims.
