Tamper-evident verification with an independent cryptographic audit trail. Alterations are detected the moment a document is verified, and Blind mode keeps privileged content encrypted on your side.
Every feature designed for legal professionals who need independently verifiable proof of document authenticity.
Present independent, cryptographically verifiable proof of document integrity that any judge or opposing counsel can check on the spot.
Even a single byte change triggers a visual forgery alert. The live holographic stamp freezes red — immediate, visible evidence that the document has been altered since issuance.
Every document is cryptographically sealed with a timestamp, creating a chain-of-custody record that any party can independently verify and that cannot be altered after issuance.
In Blind mode, privileged documents are encrypted in your browser before upload — Vertifile processes ciphertext and fingerprints, not readable content. Attorney-client privilege stays where it belongs: with you.
From contracts to court filings, every document type in your practice benefits from verifiable authenticity.
