Out-of-band verification

In plain language

Checking a request by a different route, such as phoning a number you already had, before you act on it.

The metaphor

Like calling the number in your own address book: the number printed on the letter can lie, your book cannot.

How it works

  • Use a phone number or channel you already trust.
  • Never use the contact details in the suspicious message.
  • Always confirm changes to payment details this way.
  • Agree a code word for urgent requests.

How WILDCARD handles it

Phishing Training builds the call-back habit. A payment-change rule is a vCIO policy.

In practice
  • A supplier's bank details change by email.
  • The boss emails for gift cards.
  • A client asks to redirect a wire.

A question owners ask

Isn't a call-back a hassle? It takes two minutes, and it stops the costliest scams.
