Security Suite Common (SISL fork)
Base library for the MageSpecialist Security Suite (LockDown, IP allowlists, event logging). Pulled in as a dependency of Admin Restriction and Shield. Runs on 2.4.9.
Base library for the MageSpecialist Security Suite - shared interfaces and services (a 403 LockDown, IP allowlist handling, security event logging) that Admin IP Restriction and Shield build on.
You usually don't install it directly - it's pulled in as a dependency. Maintained fork of the abandoned msp/security-suite-common (public 2.2.0 blocks PHP 8.4). Verified on Magento 2.4.9 / PHP 8.4. Install via VCS + dev-main.
