We didn't want to build Baystacks. We just wanted to run Dirt Cheap Decals. But when existing fraud apps failed to stop card testing and tanked our SEO, we built Storefront Sentry. Real protection. Zero theatrics. Built by merchants, for merchants.
By installing Storefront Sentry you agree to our Terms of Service and Privacy Policy.
Protecting stores across every industry
Automated attacks, VPN abuse, and fake checkouts silently drain revenue from Shopify stores every day. Without protection, bad traffic can distort analytics, create fake orders, and overwhelm operations.
Automated scripts create fake carts, scrape inventory, and overwhelm storefront infrastructure.
Attackers hide behind VPNs, proxies, and anonymized networks to bypass traditional fraud detection.
Fake sessions and bot traffic corrupt analytics, making it impossible to trust marketing data.

Modern bots skip your storefront entirely and hit checkout directly. Here's exactly how the attack unfolds and where Storefront Sentry shuts it down.
Automated scripts POST straight to Shopify's checkout endpoint, bypassing the storefront entirely.
Our Shopify Function intercepts every checkout and looks for our cryptographic pass; a token only issued after we verify the user is a human. The bots will never have this token.
Missing token, blank token, any value that isn't a valid cryptographically signed pass is blocked before carts can even be made. No chargebacks possible from an attempt that never reaches your checkout.
Sophisticated bots may try to fake a token but every attempt is rejected. Our ECDSA signature is mathematically unforgeable without the private key.
Customers who browsed your store already have a valid, cart-bound, shop-bound token with a short TTL. They never see a challenge or delay. Security is completely transparent to legitimate buyers.
Storefront Sentry blocks bot checkouts before they reach your payment processor, but you will still see the aborted attempts in your analytics. These will slow down over time with Storefront Guard enabled, as the attackers realize you are no longer an easy target and start becoming too expensive. They will move on to the next target, one without Storefront Sentry.
It's not just the refund. Every fraudulent order triggers processor fees, operational drag, and dispute overhead that compounds silently across your store.
The full order amount is reversed. You lose the product and the payment.
Processors charge $15–$100 per dispute regardless of outcome. Win or lose, you pay.
Shipping, picking, packing, and support hours — unrecoverable even after a won dispute.
Combined real cost. At scale, even a 1% fraud rate can wipe your entire profit margin.
Drag the slider to your monthly order volume. See what even a small fraud rate costs.
