Best WAF for Magento
Protect your Magento or Adobe Commerce store from Magekart attacks, payment fraud, and platform-specific vulnerabilities with specialized WAF solutions.
Magento and Adobe Commerce stores are high-value targets for attackers due to the payment data they process. Magekart attacks, which inject malicious JavaScript to skim credit card data, have compromised thousands of Magento stores. Generic WAFs often miss these platform-specific threats.
The best WAF for Magento understands the platform's architecture—its admin panel, REST and GraphQL APIs, extension ecosystem, and multi-store capabilities. This guide compares WAF solutions specifically evaluated for Magento and Adobe Commerce protection.
Top WAF Providers for Magento

What to Look For in a WAF for Magento
Magento-specific WAF requirements:
- Magekart Protection - Detection of malicious JavaScript injection on payment pages and checkout flows
- Origin-Based Protection - WAF that operates at the application layer, not just CDN edge, to catch server-side compromises
- Platform Awareness - Understanding of Magento admin paths, API endpoints, and common extension vulnerabilities
- Low False Positives - Don't block legitimate checkout or admin operations, especially during high-traffic sales events
- PCI DSS Compliance - Support for payment card industry security standards, critical for any store processing payments
- Composer Integration - Easy deployment via Magento's package manager for seamless updates
Magento Considerations
Magento-specific security considerations:
- CDN Bypass Risk - Attackers who discover your origin server can bypass CDN-only WAFs entirely. Origin-level protection is essential for Magento stores.
- Admin Panel Protection - Magento admin URLs need special rate limiting, IP restrictions, and access controls. Use a custom admin URL path and protect it with your WAF.
- Extension Vulnerabilities - Third-party extensions are a common attack vector. Your WAF should detect exploitation of known extension CVEs.
- Multi-Store Setup - WAF should handle Magento's multi-store architecture without blocking cross-store functionality.
- API Security - GraphQL and REST APIs need dedicated protection, especially for headless Magento setups using PWA Studio or custom frontends.
Frequently Asked Questions
Should I use Sansec Shield or Cloudflare for my Magento store?
Use both. Cloudflare provides DDoS protection and CDN caching at the edge, while Sansec Shield provides origin-based protection that catches platform-specific attacks Cloudflare would miss. This defense-in-depth approach is recommended for high-value Magento stores.
What is a Magekart attack and how do WAFs prevent it?
Magekart attacks inject malicious JavaScript into your checkout pages to steal credit card data. Origin-based WAFs like Sansec Shield can detect unauthorized code modifications that CDN-based WAFs cannot see because the attack happens at the server level.
Does Sansec Shield work with Adobe Commerce Cloud?
Yes, Sansec Shield supports Adobe Commerce on Cloud infrastructure. It installs as a Composer module and works alongside Adobe's built-in Fastly WAF for additional protection.
My Magento store is on Magento 1. What WAF should I use?
Magento 1 reached end-of-life in June 2020 and no longer receives security patches. While CDN-based WAFs like Cloudflare can provide some protection, you should prioritize migrating to Magento 2 or Adobe Commerce. Sansec Shield only supports Magento 2.3+.
