Digital ID for Every Transaction
Proof offers a reusable, IAL2-standard Digital ID that customers verify once through biometric and document authentication, enabling secure, auditable identity verification across multiple transactions and organizations without repeated reverification, thereby reducing fraud risk, customer friction, and compliance burdens for enterprises.
The last identity check your customer will ever need
Your customers verify once and carry that identity everywhere. You get a verified, auditable record for every transaction they authorize.
An identity solution that doesn't require constant reverification
Traditional IDV treats every transaction as a first-time event, so costs compound, customers abandon, and fraud exposure grows with every new submission. Gartner predicts that by 2026, 30% of enterprises will no longer consider standalone identity verification solutions reliable in isolation due to AI-generated deepfakes.

A credential that lasts
When a customer verifies identity with Proof, they complete an IAL2-standard verification with ID capture and a biometric image check, then receive a reusable Digital ID.
Users only need to submit documents once. Every subsequent interaction across Proof's network only requires a quick biometric scan.
Issued to a person, not a system
Most organizations treat identity data as something they hold: a record in their database, invisible everywhere else.
Proof issues a credential your customer owns — one that travels with them across every product, platform, and organization in Proof's network. It's cryptographically bound to them, so it can't be stolen or siloed to a single system.
Built for enterprise trust
Proof’s Digital ID gives compliance and security teams the controls regulated industries require, without creating the friction customers have come to expect from traditional identity verification.
IAL2-standard verification
Every digital identity meets IAL2 requirements, combining document authentication, biometric matching, and liveness detection in a single enrollment.
Instant re-authentication
Returning users don’t have to repeat the full process. The next time they transact with Proof, they complete a quick biometric check against their saved credential and are ready to proceed.
Cryptographic audit trail
Every document signing, notarization, and transaction authorization is cryptographically tied to the verified credential, creating a tamper-evident verifiable record.
A credential customers carry
Enrollment issues the user a Digital ID Card, a reusable credential recognized across the Proof network. One card, accepted by every Proof-enabled product, platform, and organization they encounter.
Network-level fraud protection
An identity flagged as suspicious in one context raises a signal across every other context in the Proof network, so fraud detected anywhere protects everywhere.
The identity layer your business builds on
Proof creates the last verification your customers ever need, whether they're opening an account, signing a document, completing a high-value transaction, or accessing a new product in your portfolio. One credential. Every use case.
