Why VouchSafe exists
Small businesses lose money to fraud that works through trust: a supplier email that looks right, a call that sounds like the boss. Generative AI makes those messages and voices cheap to fake. VouchSafe exists to make the one control that still works, calling back on a number you already hold, impossible to skip.
What we believe
- Verify, don't detect. Spotting AI-written text or a cloned voice is a race defenders lose. A callback on a number already on file works however good the fake is.
- One rule, everywhere. No money moves and no bank detail changes until the real person confirms it on a number already on file, and above your threshold a second person approves.
- Plain language for teams without a security department. Clear verdicts and steps staff can follow under pressure.
- Honest numbers. We publish how we test the risk engine, and we don't show accuracy figures we can't back up.
Who's behind VouchSafe
Dr. John Négus Adu, founder
VouchSafe was built by Dr. John Négus Adu, a legal scholar who has spent his career on the problem it solves: how criminals use technology to steal, and how law and process can stop them.
John holds a PhD in cybercrimes and digital governance, along with an LL.M. and an MBA, and is a published author on cybersecurity law. Over more than 20 years he has worked across legal systems in the United States, Francophone Africa and the Indian Ocean region, where payment fraud crosses borders faster than the institutions meant to catch it.
That work led to one conclusion that shapes everything in VouchSafe: you can't out-detect a good fake, but you can out-process it. Deepfake detectors and spam filters will always trail the attackers. A callback to a number you already hold, plus a second person who must approve, works no matter how convincing the email, voice or video is. VouchSafe exists to make that control fast, consistent and impossible to skip, and to leave an audit trail a bank or insurer can rely on.
VouchSafe is an independent company based in San Francisco.
VouchSafe is a software product, not a law firm, and nothing on this site is legal advice.
