Voice authentication & fraud prevention

Stop voice fraud
before it speaks.

Voice authentication and fraud prevention for contact centers, digital channels and banking. Powered by our technology partnership with ValidSoft.

The problem

Modern identity threats have entirely outrun the tools meant to protect it.

Generative AI can clone a voice from seconds of audio. Passwords, PINs and security questions leak — and frustrate.

AI voice cloning

Generative AI clones a convincing voice from seconds of public audio — defeating caller ID and voice-based trust.

Leaky credentials

Passwords, PINs and security questions are phished, leaked and reused — and frustrate the very customers they're meant to protect.

Account takeover

Social engineering and replay attacks slip past legacy defenses, driving fraud losses across contact centers and digital channels.

Our Approach

Three questions asked
on every interaction.

Vpronix asks whether a voice is a real human, the right human, and intends the right outcome.

1

Is it a real human?

Multi-dimensional liveness and deepfake detection separates genuine speech from synthetic, cloned, replayed and robo-call audio on every interaction.

2

Is it the right human?

Passive, text-independent speaker verification confirms identity from a few seconds of natural conversation — no passphrase or PIN.

3

Is it the right outcome?

Cryptographically generated digits, voiced by the user, bind approval to a specific transaction for true non-repudiation.

The Solution

Three questions answered,
scored on every interaction.

Vpronix asks whether a voice is a real human, the right human, and intends the right outcome — then layers fraud screening and continuous authentication on top, across voice and digital channels.

Voice authentication

Is it the right human? Passive, text-independent speaker verification confirms identity from a few seconds of natural conversation — no passphrase or PIN.

Watchlist & fraud screening

Blacklist, whitelist and N:M duplicate-enrollment checks flag known fraudsters and stop account-takeover before it starts.

Deepfake & liveness detection

Is it a real human? Multi-dimensional analysis separates genuine speech from synthetic, cloned, replayed and robo-call audio on every interaction.

Voice MFA & transaction signing

Is it the right outcome? Cryptographically generated digits, voiced by the user, bind approval to a specific transaction for true non-repudiation.

Language-agnostic & future-proof

Fully language-independent models, with voiceprints that adapt over time to keep accuracy high as voices change.

Continuous authentication

Passive monitoring across a live session catches mid-call handovers and social-engineering attempts as they happen.

Where it is used

Built for the channels
where fraud shows up.

Banking & payments

Stop account-takeover and authorize card-not-present and high-value payments with voice MFA.

Contact centers

Authenticate callers passively and screen every call for deepfake and replay audio — cutting handle time and fraud.

Digital channels

Frictionless voice authentication across mobile apps, web portals and messaging like WhatsApp.

Insurance

Verify policyholders in seconds and cut fraudulent claims and call-center friction.

E-commerce

Secure card-not-present checkout and stop friendly fraud with voice-signed approvals.

Enterprise MFA

Replace OTPs for remote access (PAM/IAM) with phishing-resistant voice authentication.

How it works

From a few seconds of speech
to a trusted decision.

01 / CAPTURE

Any channel

Telephony, IVR, mobile app, web and messaging.

02 / EXTRACT

Voiceprint

Irreversible 512-d template; raw audio optional to retain.

03 / ASSESS

Liveness

Replay & synthetic-speech scored independently.

04 / MATCH

1:1 / 1:N

Verify a claim or search a database in seconds.

05 / DECIDE

Decision

Verify, challenge or block — returned in milliseconds.

Deployment

Deploy it your way.

Vpronix runs where your business needs it — cloud SaaS, on-premise or on-device — with an API-first architecture that drops into your existing contact-center and digital stack.

  • Cloud SaaS, on-premise or fully on-device deployment
  • API-first with a full SDK and robust enterprise APIs
  • Pre-integrated with leading contact-center platforms
  • Low-latency engine built for real-time voice streams

Cloud SaaS

Multi-tenant, elastic and scalable — go live fast with managed updates.

On-premise

Single-tenant install inside your own data center or private cloud.

On-device

Run inference on the endpoint for the lowest latency and data minimization.
