<h4>WordPress Security Plugin & Firewall (WAF)</h4>
Every day, automated bots and hackers bombard websites with attacks. Mass botnets, fake search engine crawlers, brute-force login attempts, and spam bots can overwhelm your WordPress site – stealing data, overloading your server, and defacing content. It’s a 24/7 threat to your business. If you’re looking for WordPress site protection, you need a proactive defense that stops these attacks before they reach your website.
BotBlocker Security is the all-in-one solution to keep your site safe from automated threats. This powerful WordPress security plugin and Web Application Firewall (WAF) acts as a dedicated anti-bot firewall, blocking malicious traffic at the front gate without slowing down your site.
BotBlocker’s setup and onboarding experience allows anyone to secure their WordPress site in under 1 minute, regardless of technical expertise. You can rest assured knowing you have enabled the right site protection settings to protect your website.
<h4>🔥 WordPress Firewall (WAF)</h4>
BotBlocker Security includes an endpoint firewall/WAF that identifies and blocks malicious traffic before it reaches WordPress. Built and maintained by a team focused 100% on WordPress security, our Web Application Firewall protects your site while reducing server load.
BotBlocker intercepts bad traffic at the earliest stage – even before WordPress or your theme loads. By running as a must-use plugin (MU-plugin) on early init, it blocks threats before WordPress initializes, drastically reducing server load during attacks.
Key Firewall Features:
<ul>
<li>Real-time firewall rule updates via the BotBlocker Threat Defense Feed</li>
<li>Real-time IP Blocklist blocks all requests from the most malicious IPs</li>
<li>Early-init protection – blocks threats before WordPress loads</li>

<li>No personal data collected – only technical request parameters analyzed (100% GDPR/CCPA-compliant)</li>
<li>Brute force protection with login attempt limits and multi-layer verification</li>
</ul>
