WPMU DEV Defender Pro

Defender Pro (developed by WPMU DEV) is a comprehensive cybersecurity and hardening suite built to protect WordPress websites from vulnerabilities, unauthorized intrusions, and malicious bot traffic. It replaces complex server-level security configurations with intuitive one-click hardening tweaks, automated scheduled file scanning, and real-time firewall monitoring. Featuring two-factor authentication (2FA), login masking, Google reCAPTCHA integration, audit logging, and automated IP lockouts, Defender Pro shields mission-critical stores and enterprise portals without degrading server performance.

Main Features

• Automated malware & core integrity scans — Regularly scan WordPress core, theme, and plugin files against the official WordPress repository to detect unauthorized code changes or suspicious file additions.
• Web Application Firewall (WAF) — Block SQL injections, cross-site scripting (XSS), bad user agents, and malicious URL queries before they reach your site.
• Brute-force protection & IP lockouts — Automatically ban malicious IP addresses attempting repeated failed logins or aggressive 404 scanning.
• Two-Factor Authentication (2FA) — Protect user logins via Google Authenticator, Authy, or mobile TOTP apps with fallback verification options.
• One-click security hardening — Implement essential security recommendations in seconds, including disabling file editing, changing default database prefixes, and disabling XML-RPC.
• Login masking & custom URL — Obscure the default wp-login.php path to prevent bot scanning and targeted brute-force assaults.
• Audit logging & real-time alerts — Monitor all administrative actions, user logins, and settings changes with detailed timestamps and instant email alerts for suspicious behavior.
• Blocklist & allowlist management — Manage custom IP, country, and bot allowlists or blocklists directly from an intuitive security dashboard.

Benefits

• Proactive threat prevention — Blocks malicious botnets and automated exploits before they can compromise sensitive customer or store data.
