Proteside Checkout Protection
Proteside is a client-side payment security platform for businesses that accept online payments. A script installed on the payment page runs in the buyer's browser and monitors the page for tampering. It checks that QR codes, payment keys, boleto lines and crypto wallet addresses shown to the buyer match what the business issued, and watches card fields for keyloggers, form hijacking and data exfiltration.
The product addresses attacks that alter a payment page in the browser, such as Magecart-style skimming and QR code replacement, including those delivered through compromised third-party scripts. Proteside works alongside the existing payment provider and does not process payments. It can be installed with a script tag or with plugins for WooCommerce, Adobe Commerce (Magento), OpenCart and PrestaShop.
