WPMU DEV Defender Pro is a premium, all-in-one security plugin for WordPress designed to be a “set and forget” solution. While the free version handles basic hardening, the Pro version is built for agencies and high-traffic sites that need automated threat detection and deep-system cleaning.
This is EXACTLY the same product as distributed by the developer. Sales Page Documentation
The Pro version unlocks the heavy-duty automation that the free version lacks:
Scheduled Malware Scanning: Automatically scans your entire site (including plugins and themes, not just core files) every 6 to 24 hours.
Safe Repair & Restore: If a core WordPress file is compromised, Defender can restore the original, clean version from WordPress.org with a single click.
AntiBot Global Firewall: Connects to WPMU DEV’s global network to block known malicious IPs before they even reach your site.
Google Blocklist Monitoring: It checks your site’s status against Google’s “unsafe” list and alerts you immediately if you’ve been flagged for malware.
Audit Logging: Tracks every single action taken on your site—who logged in, what plugin was updated, and what settings were changed. This is vital for forensic security.
Vulnerability Detection: Powered by Patchstack, it identifies specific security holes in your active plugins and themes and prompts you to fix them.
Beyond the Pro-specific perks, Defender handles the “dirty work” of WordPress security:
2FA (Two-Factor Authentication): Support for Google Authenticator, Authy, and even biometric locks.
Login Masking: Changes your /wp-admin or wp-login.php URL to something custom (e.g., /my-secret-door) to stop brute-force bots.
Security Headers: Adds layers like XSS Protection and HSTS to protect against code injection and session hijacking.
Automated Lockouts: Automatically bans IPs that trigger too many 404 errors (bot behavior) or fail logins too many times.
Pros:
Incredible UI: Often cited as the cleanest, most user-friendly interface in the security niche.
Zero Bloat: It’s modular; you only turn on what you need.
Bundled Value: If you use their other tools (Smush, Hummingbird), the cost-per-plugin becomes very low.
24/7 Support: Their support team is famous for logging into your site and fixing issues for you.
