The problem
Fraud gets in through the blind spot: the phone.
Digital channels are protected, but fraud gets in through a call or a text message the user believes is legitimate. With spoofing (a cloned number), the attack arrives with the institution’s name and number.
A single call can cost more than investing in phone security.Social engineering is the number one digital crime by incidence, danger and profitability for criminals.
Regulatory and reputational riskCONDUSEF, Mexico’s financial consumer protection agency, publishes the Financial Institutions Bureau, which publicly compares the volume of fraud complaints across institutions. It is a visible risk, not just an internal one.
