Free Malware Scanner: Stop security threats before they harm your site

If your site has been infected by malware, this malicious code can cause a lot of damage before you even realize it’s there. Hackers use malware, often hidden in themes, extensions and plugins, to steal personal data, encrypt files for ransom, or spy on your activity.

Defender gives you a highly-effective yet easy-to-use malware scanner that runs deep diagnostics across your entire site, making sure no malware is lurking in the shadows.

Defender will scan your site for:

• Files that have changed unexpectedly: The scan will compare all core files and extensions against the official WordPress repository and flag any modifications or rogue additions instantly.
• Known vulnerabilities: Defender will check verified exploit registries to catch any security gaps in your active themes, plugins and core version, and help you fix them before they can be targeted.
• Suspicious code: By continually checking your server files, Defender will spot any potential code injections or backdoors, a common way bad actors try to gain access to your site.
• Outdated & removed plugins: Plugins that have been delisted from the repository or have not been updated in over two years become a significant risk to your site’s integrity. Defender flags these weak spots before they can cause a problem.

AntiBot Global Firewall: Block harmful IPs with data from over 750,000 sites

Put the collective threat intelligence of a massive network to work for your site. Powered by real-time threat data from over 750,000+ sites, the free AntiBot Global Firewall automatically blocks harmful traffic and spam bots with a single click.

When any site on our network flags a threat, all other sites get protected too. It’s like having a bouncer for your website. If an IP is on the blocklist (updated every 12 hours), they’re not getting in!

The most important part is, you’ll be in complete control.

• User-friendly setup: Defender Pro gives you AntiBot on every site you connect, regardless of where they’re hosted. Just flip the switch and it’ll start working so efficiently you won’t even notice it’s there.
• Choose your security level: Basic Mode offers balanced, everyday protection, while Strict Mode offers tighter security that blocks even the slightest suspicious activity.
• Manage IPs in The Hub: Manually block specific IPs, apply blocklists and allowlists across all sites, implement Geo IP blocking and configure everything from one central dashboard.

Firewall Security & IP Management: Take control over your site’s traffic

Defender’s advanced Web Application Firewall (WAF) makes it easy to lock out hackers, scrapers, and malicious bots without touching a single line of code.

• Advanced IP Lockouts: Manually block specific IPs, import custom blocklists, or set automated timed and permanent lockouts for repeat offenders.
• Geo IP Blocking: Instantly ban traffic from specific countries or geographic locations with a single click.
• User Agent Banning: Instantly block spam and scrapers using built-in bad bot presets. We automatically allowlist major search engines to protect your SEO.
• Malicious Bot Detector: Deploy layered defenses to trap aggressive bots that ignore your robots.txt rules and catch fake crawlers impersonating legitimate search engines.

Login Security & 2FA: Prevent unauthorized access

Make sure the only users logging into your WordPress site are the ones you actually want. Defender can protect your sites from unauthorized access or brute force attacks with sophisticated login security features.

These features keep your site safe from malicious logins, while still ensuring legitimate users can log in easily.

• Hide Login URL: Change the location of WordPress’s default login area, making it harder for automated bots to find and more convenient for your users.
• Session Security: Protect your site from session hijacking, preventing attackers from stealing session tokens to impersonate users and gain unauthorized access to your website.
• Smart Password Rules: Enforce strong passwords for new registrations, automatically block compromised credentials using a public «pwned» passwords database, limit login attempts so hackers can’t guess passwords, and force a site-wide password reset upon the next login if you suspect a security breach.
• Two-Factor Authentication (2FA): Add an extra layer of protection and security to your WordPress sites to prevent brute force attacks and login security vulnerabilities. Defender’s two-factor authentication (2FA) features include plenty of ways to verify logins, from mobile app verification (Google Authenticator, Authy) to Biometric Authentication (fingerprint/facial recognition) to Hardware Key Authentication (USB security keys.) Plus, built-in backup code generation, lost device emails and WooCommerce 2FA.

Security Hardening: Apply recommended settings with a single click

WordPress security hardening is all about adding multiple layers of protection to your website, to reduce your risk of attacks and unauthorized access.

Defender makes it easy to do this, with 12 recommended hardening settings you can apply with one click.

For example, Defender’s hardening settings include:

• Disabling the file editor to stop internal tampering
• Updating outdated security keys
• Hiding PHP error reporting on the frontend
• Adding advanced security headers (XSS protection, Strict Transport, etc.)
• Disabling trackbacks and pingbacks to prevent spam
