Changing verification decision rules is scary — maybe you’ll hurt your verification rate or introduce new fraud loopholes. Now going forward, every time you change a rule in Footprint, we’ll automatically sample hundreds of users you’ve already onboarded and show you how the new rules affect that change. Backtesting lets you make rules edits with confidence!
