What we do

Today, there is no easy way to prevent an individual from falling victim to and then making a scam or illegitimate payment

Current strategies fail to address individual needs, leaving individuals and the vulnerable hesitant to seek help from institutions due to shame, guilt and fear.

Family, friends, and trusted caregivers could play a crucial role as guardians, stepping in to assist and help address a scam before the damage is done, but they rarely become aware until too late.

Better awareness and tools could empower and directly support individuals and those guardians who care against the ever-evolving threat of scams and save billions lost to scammers where banks and governments cannot

Breach response

Your data gets leaked. Watch what happens next
