Frequently Asked Questions
Absolutely. While the term 'Magecart' originated from attacks on Magento stores, it now refers to any client-side skimming regardless of your stack. Whether you're using Shopify, custom checkout flows, React, or any other frontend, the risk is the same.
cside works across any web application or website. While many customers in e-commerce use us for PCI DSS and skimming protection, we also secure SaaS apps, fintech platforms, job boards, healthcare portals, and more. If your frontend handles sensitive data, this applies to you.
No. cside loads asynchronously and is optimized for production environments. It wraps script execution without introducing latency or blocking rendering. We cache static scripts to even improve performance.
We apply behavioral analysis to every script running in the browser. If a script attempts to read sensitive input fields (like credit card numbers), access form data, or send it to an unknown or unapproved domain, cside blocks it instantly and alerts your team.
