Shield IPS/WAF (SISL fork)
Application-level WAF/IPS for Magento 2 - inspects request params and detects SQL injection and XSS (real SQL parser, not just regex). Runs on 2.4.9.
Shield is an application-layer intrusion prevention system (IPS/WAF) for Magento. It inspects incoming GET/POST/COOKIE params for known attack patterns - SQL injection, XSS, tampering - and can block them before they reach your code, using a real SQL parser rather than plain regex.
Part of the MageSpecialist Security Suite. Maintained fork of the abandoned msp/shield (2017 release, no PHP 8.x support). Verified on Magento 2.4.9 / PHP 8.4. Install via VCS + dev-main.
