Lock in Proof, unlock trust

Proof is the only signature platform with Enhanced Signer Identification. It provides evidence about the identity, not just the transaction. It’s enriched with data about a person’s identity, device and location so that you can fully trust their signature.

Block fraud before it starts

Whether a document requires a basic signature or a notarization, Proof monitors fraud risk in every transaction. When a transaction looks suspicious, it’s flagged for your review. With Proof, we’re protecting every transaction from potential forgery.

Smart execution engine

Navigate the ever expanding sea of rules including state laws, regulatory requirements, industry standards, or company policy. Proof simplifies the complexity so you can sign with confidence knowing that it will be accepted. Finally, there’s a platform that does not require you to be an expert in the law.

Signatures that can’t be forged

Proof fuses a verified identity to every signature with a cryptographic seal. This creates a digital signature on every document which can’t be tampered with. Now you can verify who has signed, not only by the signature on the face of the document, but by verifying the unique set of cryptographic bytes for every signature.

Proof ensures that esignatures can't be forged

Rise to a new standard of trust

Proof is the first organization, approved by the Kantara Initiative to combine IAL2 identity verification with an electronic signature all on one platform. Use Proof for highly regulated use cases where strong identity assurance is required.

What transactions does Proof serve?

The Proof platform supports any digital transaction when you need evidence of not only who was identity proofed, but also that the intended person completed the transaction.

Proof transactions are legal and valid in all 50 states, with limited exceptions for remotely notarized documents. A list of online notarization exceptions can be found here.

What problem does Proof solve?

Simple eSign solutions are increasingly vulnerable to fraud as they are regularly exploited to forge or falsify signatures. 

The Proof platform fills this security gap by giving businesses the ability to add identity assurance measures to eSign transactions. In doing so, we are the first signature platform to offer identity-verified eSignatures without the need to meet with a notary.

How does Proof benefit my business?

The Proof platform offers the most complete suite of identity and signature solutions on the market.

Our platform is unique in the eSign space by allowing businesses to pair transactions with robust identity verification options based on the document type, its contents, or the industries they serve. 

Documents completed on the Proof platform also come with a robust document audit trail that give a level of transaction transparency that does not exist with paper documents and is unrivaled by other signature platforms.

How does Proof verify my identity?

Businesses can request that the Proof platform verify signer identities through a combination of authentication and verification methods. These methods may include any of: SMS authentication, knowledge-based authentication, credential analysis, analysis of a biometric selfie, or a meeting with a member of the Notarize Network.

Any transaction involving credential analysis will require an approved government-issued photo ID from this list. Any transaction involving knowledge-based authentication will require that the signer have a U.S. Social Security Number.

How does Proof protect my data?

Proof employs various security measures to ensure the security and privacy of personal information on the Proof platform, including the encryption and protection of all data in transit and at rest using AES-256 bit encryption and tracking of all application access.
