<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>Cloud-based threat intelligence – cross-checks every visitor against global threat databases</li>
<li>No visitor data collected – only technical request parameters analyzed (GDPR/CCPA-compliant)</li>
<li>Brute force protection with login attempt limits and multi-layer verification</li>
</ul>
<h4>📡 WordPress Security Scanner & Site Protection</h4>
Every attempt to access your site is thoroughly analyzed and filtered. BotBlocker provides comprehensive site protection across all entry points:
<ul>
<li>XML-RPC and API Protection – all endpoints blocked by default. Create access rules for trusted services and add allowed URLs for payment plugins</li>
<li>Spam Prevention – spammers cannot connect to your site. Automatically block IP addresses that exceed spam comment thresholds</li>
<li>File Access Protection – theme and plugin files securely protected from unauthorized access</li>
<li>Deep Analysis – User-Agent, Accept-Language, GeoIP, PTR, DNSBL, cookies, browser fingerprint, AdBlock, Incognito detection</li>
<li>Network & Protocol Control – block obsolete HTTP/1.0 clients and disable IPv6 if not used. Cloudflare-aware protection blocks origin bypass attempts</li>
</ul>
<h4>🔒 Login Security & 2FA</h4>
All login attempts pass through multi-layer filtering and CAPTCHA verification:
<ul>
<li>Two-Factor Authentication Support – 2FA enhanced login security for admin area. Backup codes for recovery access. Universal 2FA app support – works with Google Authenticator, Authy, etc.</li>
<li>Multi-layer CAPTCHA Protection – color buttons, animal images, floating shapes, floating math, Google reCAPTCHA v2/v3, and more. Any internal CAPTCHA can be combined with reCAPTCHA v3 for dual-layer protection</li>
<li>Brute Force Protection – configurable login attempt limits. Failed attempts trigger temporary bans, with escalating penalties for repeated failures</li>
<li>Advanced Anti-bot Challenges – proprietary CAPTCHA designed to be nearly impossible to bypass, even by AI-based anti-CAPTCHA services</li>
<li>Intelligent Ban System – failed CAPTCHA results in configurable ban periods. Repeated failures trigger 24-hour bans</li>
<li>Admin Access Simplification – special mechanism to ease site administrator login while maintaining security</li>
<li>XML-RPC Control – options including complete disabling</li>
</ul>
<h4>🛠️ Security Tools</h4>

<li>IP-PTR-Host Mismatch Detection – automatically detect and block fake crawlers (e.g., fake Googlebots)</li>
<li>Blacklist & Whitelist Management – instantly allow or block any IP, ASN, range, or User-Agent</li>
<li>Live Traffic Monitoring – see all traffic in real-time: robots, humans, 404 errors, logins/logouts, file requests, and content consumption</li>
