Vendor Resources


Since using Signifyd, we’ve added thousands of dollars in revenue we would normally have declined. They’re approving what we considered our riskiest orders, and we’ve been able to open up many new international countries as well.
Kaitlin Moughty
Director of Ecommerce
We didn’t find Signifyd, they found us. And what really stood out was their knowledge of our industry and our customers. They’re not just experts in ecommerce fraud, they actually know our business – so we’re comfortable trusting them with our fraud management practice.
