Maroon Horizon Smart Firewall - Malware Scanner & IP Blocking

Maroon Horizon Smart Firewall is built for practical WordPress protection: block bad traffic, scan for malware, quarantine suspicious files, and reduce attack surface — without sending your site files off-server. Advanced Security Check (Quick Scan) gives you an easy-to-understand Overall Security Rating, plus clear details and explanations for each check so you can quickly see what to improve and raise your security level. This WordPress.org (FREE) build is fully functional for the FREE feature set and is designed to run locally for those features. Advanced capabilities are provided by a separate commercial PRO plugin (not included in this WordPress.org build). Outbound network requests (if any) are disclosed under "External Services" and "Privacy". What you get in the FREE plugin (local-only)

• Advanced Security Check (Quick Scan) with an Overall Security Rating and easy-to-follow explanations so you can improve your security level step by step.
• Manual IP blocking and IP management.
• Security patch toggles for common hardening actions.
• Malware scanning of uploads and theme directories using local pattern detection (no external signatures).
• Quarantine management (restore / delete quarantined files).
