Checks checkout pages for scam domains, lookalike sites, hidden extras and risky payment signs before you pay. Know if a checkout page is safe before you enter your card details. Checkout Security Shield is a free browser extension that checks any checkout or payment page for warning signs — before you pay, not after you've been scammed. WHAT IT CHECKS ON EVERY CHECKOUT PAGE: ✓ Payment gateway verification — see if the page uses a recognized, trusted payment processor. If a checkout asks for your card with no recognized processor, you'll see a clear warning. ✓ Known scam domain alerts — checks the site against a list of tens of thousands of domains reported for fraud and phishing. If you land on one, you'll get a warning before you enter any payment information. ✓ Lookalike domain alerts — warns when a site's address imitates a well-known brand, on any page. ✓ Payment red flags — flags checkouts that only accept bank transfer, cryptocurrency or gift cards. ✓ Hidden extras — flags pre-checked boxes for insurance, subscriptions, newsletters, or "premium" add-ons that get added to your order unless you uncheck them. ✓ Unencrypted connection warning — alerts you if a checkout page isn't using a secure connection. ✓ Auto-renewal warnings — flags when a purchase will renew automatically. WHY IT'S DIFFERENT - 100% free, no account, no sign-up - Works automatically, no configuration needed - Nothing is collected or sent — everything runs locally in your browser - One click to turn it on or off, or to trust a site, from the extension popup
