Know it’s really them,
on every call.
Fraudsters pretend to be your organisation to your customers, your customers to your staff, and your managers to your own team. Hongi gives each of those calls a short spoken check that a cloned voice or a spoofed number alone can’t pass.

From anyone who gets your call to the colleague next door
Every Hongi check works the same way: each side reads a different short code, new every 30 seconds. What changes is who is on the other end.

Real Hongi app screens with fictional demo data
Built so a stolen voice isn’t enough
Three of the five rules every Hongi check follows.
The secret is never spoken
People read short codes made from a secret that is never shown, typed, spoken or sent. Overhearing a call gives nothing reusable.
Codes expire in 30 seconds
A recorded code is worthless within about a minute and a half.
Two different codes
Hearing one side doesn’t reveal the other, so an impostor can’t simply repeat what they heard.
