Fraud Solution Profile

Signifyd is the world’s largest provider of guaranteed fraud protection for ecommerce. Now with more than 10,000 customers, Signifyd started with the idea that the liability for fraud is unfairly placed on online merchants. The company uses big data and machine learning to approve or decline within milliseconds virtually every order it reviews. A small fraction of edge cases are decided by expert manual review.

Signifyd’s guarantee model shifts the financial liability for fraud from a merchant to Signifyd, while all but eliminating the need for tedious and costly manual review.

If Signifyd approves an order that later turns out to be fraudulent, it will make the merchant financially whole. Signifyd is paid only on orders it approves and so Signifyd’s interests are aligned with its customers.

The fraud guarantee means merchants can expand into new markets, including internationally, and that they can ship more orders that they otherwise might have declined for fear of fraud.

In the end, Signifyd is working to help its customers provide a friction-free shopping experience for their customers by ensuring that consumers’ orders will be approved quickly and that their legitimate orders will not be flagged for fraud and declined.

The company was named a Cool Vendor in Gartner’s 2017 “Security for Midsize Enterprises” report. It was also named to the Forbes FinTech 50 and included among Bloomberg’s 50 Most Promising Startups. Signifyd has been listed as having a Top Company Culture by Entrepreneur and the company was also recently named to Inc. Magazine’s Best Workplaces for 2018 and recognized by the San Francisco Business Times and Silicon Valley Business Journal as one of the Bay Area’s Best Places to Work.

Signifyd protects over 10,000 e-commerce merchants and has protected billions in transactions for customers like Bonobos,, and Lacoste while reaching thousands of merchants through partners like Accertify, BigCommerce, Magento, Shopify and Salesforce Commerce Cloud with seamless integration.
