What is BotBlocker?

BotBlocker Security blocks 99% of automated attacks before WordPress even loads. No bloat, no slowdowns, no monthly fees for core protection. Setup in 60 seconds.

Three interception layers stop bad traffic at wp-config.php (before WordPress), MU-plugin phase, and the main shield - saving 30–100ms and 5–20MB RAM per blocked request. Competitors react after WordPress boots; BotBlocker stops threats at the door.

3,000+ active installations · 8 languages · GDPR / CCPA compliant · Works with Cloudflare, WP Rocket, LiteSpeed, WooCommerce, Elementor, multisite, IPv6
