Voice fraud defence for live phone lines.

DeepBlocker Real-Time Protection sits in front of any phone number you want defended. Every inbound call is intercepted by a Zero-Trust Voice Agent that screens the audio for synthetic-voice signatures, scores the request itself, and decides whether to transfer to a human or terminate the call. The attacker never reaches your team.

Who it's for

  • Banks, fintechs, treasury and payments operations.
  • Customer-service and helpdesk lines vulnerable to ATO and password-reset fraud.
  • Executives and finance teams targeted by CEO-fraud calls.
  • Telecoms operators offering fraud-defence as a value-added service.

How it works

  1. Forward the protected number to DeepBlocker. No carrier integration. No bank cooperation required.
  2. The Zero-Trust Voice Agent answers every call. The caller is greeted, the audio is analysed in real time on the same G.711 transport fraudsters use.
  3. Three-band verdict in real time: REAL → transferred to your team. UNCERTAIN → routed to human review. FAKE → terminated, audit log written.
  4. Every decision produces an audit trail: voice analysis score, three-band verdict, transcript, and disposition.
