WPMU DEV Defender Pro

Defender Pro is a WordPress security plugin built into the WPMU DEV platform. It runs scheduled scans for malware, suspicious code, and vulnerable plugins, blocks bad traffic before it reaches WordPress, and adds login protections such as two-factor authentication. It also sends automated security reports and can repair modified WordPress core files in one click.

Key Features

• Scheduled Malware Scanning – Scans run on a schedule you set, checking for malicious code, suspicious injections, vulnerable plugins, and missing hardening recommendations.
• Built-in Firewall – Traffic is filtered before it reaches WordPress, using an anti-bot firewall, IP logging, user-agent blocklists, and login masking to cut down bots, spam, and brute-force attempts.
• Login Protection – Accounts can be secured with automatic two-factor authentication, biometric login, CAPTCHA options, and checks against known pwned passwords.
• Vulnerability Detection – The plugin watches for known vulnerabilities so you can act on weak points in your site before they are exploited.
• Safe Repair – If a WordPress core file has been changed, Safe Repair restores or replaces it in one click instead of leaving you to fix it manually.
• File Change Detection – The plugin flags modified core files and other suspicious changes, along with audit logs and alerts, so hacked sites are caught quickly.

Who Is It For

Defender Pro is aimed at WordPress users who manage real or client sites and want security handled from one plugin rather than checked site by site. It suits agencies and freelancers who need scheduled scans, alerts, and clearer reporting across multiple sites.
