Voice-clone & BEC payment fraud defence

The voice on the phone isn't proof anymore.
The callback is.

A cloned owner's voice tells your bookkeeper to change bank details or wire funds. CallbackShield turns the proven defence — call back on the number on file, trade a one-time code phrase — into a 60-second flow your staff will actually follow under pressure.

FBI IC3 recorded $3.046 billion in business email compromise losses. The attack is a phone call. The defence is a callback — with tooling, not a policy PDF nobody reads.

How a verification works

Open a case. A payment request or bank-detail change arrives — by phone, email, or message. Staff open a case: who asked, what change, how much.
Get the code phrase. CallbackShield generates a rotating code phrase that expires in 30 minutes, shown on a secure token card.
Call the number on file. Never a number supplied in the request. Read the phrase to the real approver on that call.
Approver confirms in the case. The approver opens the one-tap link, checks the request, and types the phrase they just heard. Wrong or expired phrase? Nothing is confirmed — and every step is timestamp-logged.

Free — the complete job

Unlimited verification cases for bank-detail changes and urgent payments, rotating expiring code phrases, the known-number callback checklist, and a full timestamp log per case. No credit card.

Paid — the vault & the rules

Vendor bank-change vault (no vendor detail changes without a confirmed case), dual-approval rules, team members and roles, and insurer-ready incident log exports (PDF/CSV).

Built for pressure

Oversized confirmation states, one decision per screen, plain language. Designed for the bookkeeper who just got a scary call — not for a security team.
