The problem

Identity has 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. Vpronix answers three questions on every interaction: is the voice a real human, is it the right human, and is this the outcome they intend — stopping fraud without adding friction.

Deepfake-aware

Patented detection of synthetic, cloned and replayed speech flags AI-generated voices before they ever reach an agent, IVR or app.

Frictionless

Passive, text-independent authentication verifies customers from natural speech — no passphrases, PINs or security questions.

Privacy-first

Voiceprints are mathematical and contain no PII — backed by EU privacy seals and aligned to GDPR, CCPA, HIPAA and BIPA.

The platform

Three questions, 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.

How it works

From a few seconds of speech to a trusted decision.

01 / CAPTURE

Capture audio

Speech arrives from any channel — telephony, IVR, mobile app, web or messaging — as real-time streams or batch.

02 / EXTRACT

Extract features

Key acoustic and behavioral features are extracted from the raw audio; nothing personally identifiable is retained.

03 / INFER

Score in parallel

Deep neural networks assess liveness, deepfake risk and speaker identity together, in milliseconds.

04 / DECIDE

Voiceprint & decide

A mathematical voiceprint with no PII returns a verify, challenge or block decision your systems act on instantly.

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.

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.

Accuracy

Benchmarked where it counts.

Independent, NIST-style evaluation across clean, telephone and noisy conditions, plus adversarial deepfake and replay attacks. Vpronix is tuned for the hard cases — short utterances, cross-channel audio and generative-AI spoofing.
