Overview
WordPress sites attract bots, brute-force login attempts and malicious files, and checking for them by hand takes time. WPMU DEV Defender Pro groups the main protections into one plugin. It runs scheduled malware scans, checks for known vulnerabilities, and offers repair options for suspicious files. A security recommendations list points out what needs attention, and bulk fixes let you resolve several issues at once.
The plugin also controls who can reach your site and how they sign in. You can add two-factor authentication, mask the login page, block countries or IP addresses, and keep audit logs of security events. Automated reports keep you informed, and white label branding lets agencies present the plugin to clients as their own. It fits a single site or a larger set of client sites managed from a central dashboard.
Features
- Scheduled malware scanning: Scans run automatically to detect malware threats, so you can respond early. Scan details for a suspicious code issue are displayed with automatic scrolling to the relevant part.
- AntiBot Global Firewall: Blocks malicious IPs in advance to cut down spam and attacks from harmful visitors. Firewall logs show a country name tooltip when you hover over a flag.
- Patchstack-powered vulnerability detection: Uses Patchstack vulnerability intelligence to identify security risks on your site, with bulk fixes available to resolve several vulnerabilities at the same time.
- Safe repair for suspicious files: Repair or replace suspicious and compromised files with one click, which helps restore the integrity of your site after a scan turns up a problem.
- Two-factor authentication: Adds an authenticator app or biometric step to the login process, which reduces the chance of unauthorized access to user accounts.
- Login protection and masking: Hide your WordPress login page and defend against brute-force attempts. Google reCAPTCHA can also screen bots and spam on forms and login pages.
- Geolocation and IP blocking: Block visitors from specific countries or suspicious IP addresses, and manage custom lists of allowed and blocked IPs across multiple sites.
- Reports, logs and white label: Automated security reports and detailed audit logs track events and admin actions. White label branding lets agencies and freelancers present the plugin under their own name.
Best for
- Agencies managing security across many client sites
- Site owners who want malware scanning and a firewall
- Freelancers who need white label security for clients
