Finowl for E-commerce
Protect shopper accounts and understand your customers
Online stores keep saved cards, addresses, gift card balances and loyalty points behind a simple email and password. That is exactly what account takeover crews look for. They run leaked credential lists against storefront logins, then drain points or place orders to new shipping addresses. Finowl lets your checkout and account services ask two quick questions: has this shopper’s email shown up in breaches, and is this password already circulating in breach data?
Merchandising and marketing teams have a different question: who is actually buying? The Finowl gender API estimates how a first name is typically used, which helps analysts size audiences for catalog planning and check campaign reach in aggregate. It should never change prices, discounts or what a shopper is allowed to buy, and shoppers should always be able to pick their own preferences, such as which department they want to browse.
WHAT TEAMS RUN INTO
Challenges in e-commerce
Loyalty and gift card draining
Stored value is easy to cash out. Attackers who log in with reused credentials redeem points or gift card balances within minutes, often before the shopper notices anything.
Shipping address changes
A takeover often shows up as a new delivery address followed by a high-value order. Teams need extra signals to decide when that change deserves a second confirmation.
Checkout friction
Every additional step at checkout costs conversions, so security controls must be targeted at risky sessions instead of applied to every shopper on every order.
Guesswork in audience planning
Many stores collect only an email and a name, which leaves merchandising teams guessing about the audience mix behind each category, campaign and seasonal collection.
HOW FINOWL HELPS
Three APIs, one integration

Email breach checks for online stores and shopper logins
Most account takeovers at online stores start with an email address that already sits in a breach dump. The Finowl email breach API returns whether an address appears in known breaches, which ones, and what data each exposed. A store can use that context to decide when a login, a new shipping address or a large loyalty redemption deserves a second look.

Breached password screening for e-commerce accounts
Shoppers rarely create a fresh password for every store they buy from, so the password they type into your registration form may already be on a credential stuffing list. The Finowl password breach API checks that value against breach data and returns whether it has been seen and how often, letting you ask for a different one before the account goes live.

Gender insights from names for e-commerce analytics
E-commerce analysts often have a name and an order history but little else. The Finowl gender API estimates how a first name is typically used, returning a confidence score and sample count, so teams can describe the audience behind a category or campaign in aggregate and plan catalogs with fewer blind spots.
