Free Chrome extension: know if a checkout is safe before you pay
Checkout Security Shield checks the payment gateway, hidden extras, and site reputation on any checkout page, right in your browser. 100% free, no account, no data collected.
Four checks, on every checkout page
- Verified payment gateway — flags whether the page uses a known, trusted processor (Stripe, PayPal, and others) or an unrecognized one asking for your card.
- Hidden pre-checked extras — surfaces added insurance, subscriptions, or upsells that were silently pre-selected for you.
- Unencrypted connections — warns if you're about to enter card details on a page that isn't using HTTPS.
- Known fraud domains — checks the site against a bundled list of domains reported for fraud.
Entirely on your device
Every check runs locally, inside your browser. The extension makes zero network requests and collects zero data — no personal information, no browsing history, no payment details. The fraud-domain list is bundled inside the extension itself, so checking a site against it never leaves your device.
The only thing it stores is a single on/off toggle, saved locally on your computer. No account, no sign-up, nothing to configure.
Install it in a few seconds
Add it from the Chrome Web Store, and it's ready — no setup, no account. It runs quietly and only shows something when there's a reason to.
