Voice fraud defence for banks, fintechs and treasury operations.
Voice cloning takes one minute of audio. The result: helpdesk impersonation, CFO fraud, password-reset abuse and synthetic-identity onboarding at carrier-grade scale. DeepBlocker is the only voice deepfake detector with a published model card that holds up on real phone lines.
Voice is now the primary channel for high-value financial fraud.
- £1.17B stolen from UK victims to authorised push-payment and impersonation fraud (UK Finance, 2025).
- $16.6B in reported losses to cybercrime, with vishing and impersonation accounting for the fastest-growing categories (FBI IC3, 2024).
- 60% of firms experienced at least one deepfake-driven incident in the last twelve months (Thales, 2026).
- Voice authentication is "fully defeated", per Sam Altman addressing the US Federal Reserve in 2024. Most banks still rely on it.
The three voice-attack surfaces inside a financial institution.
Account takeover via password resets, address changes, and SIM-swap requests. DeepBlocker intercepts the call, verifies the speaker, and pushes high-risk requests to verified processes — never approves a sensitive change by phone.
Spoofed CEO/CFO calls instructing wire transfers or vendor changes. DeepBlocker terminates synthetic-voice calls before they reach the human, and routes the audit trail to your fraud team.
Synthetic-voice fraud during phone-based KYC and re-verification. DeepBlocker Detect plugs into your existing fraud-decisioning stack as a hosted API — same telephony-tuned model that powers Real-Time Protection.
Reproducible, telephony-tuned, model-card-grade.
Measured on 207 real phone calls, both models scored on the same calls the way production scores them. We publish methodology and per-source breakdown — including known limitations — in the model card. Onecom-grade due-diligence is reproducible from the open base model.
Built for FCA, DORA, NIS2, and GDPR obligations.
- FCA Consumer Duty: evidence of meaningful steps to prevent foreseeable harm — every blocked deepfake call has a complete audit trail.
- DORA (EU 2554/2022): ICT third-party risk management and operational resilience. DeepBlocker contracts include sub-processor disclosure and exit-plan support.
- NIS2: incident reporting hooks into existing SOC tooling. Per-call disposition logs are exportable to Splunk / Sentinel / Elastic.
- GDPR: per-tenant retention, encryption, and access controls; data-residency options on request.
A 2–4 week board-ready output, before you commit.
- Risk-scored map of every voice-triggered workflow inside the bank.
- Simulated vishing exercises against your contact-centre and treasury teams, with transcripts.
- Quick-wins list: changes you can make this quarter without a procurement cycle.
- Structural roadmap: where Real-Time Protection or Detect sit in your existing stack.
