When it comes to safeguarding customer assets, even if you get it right 99.99% of the time, it’s the 0.01% that makes headlines people remember you for. As they say, trust takes a long time to gain, but only a split second to lose.

With account-takeover scams (ATO) accelerating to full throttle in recent years, and website impersonation more accessible than ever, that split second of ATO meltdown can come without warning, or the luxury of foresight and visibility.
