WordPress Firewall & Bot Protection
Stop bots, brute force, spam, and fake crawlers - before they reach WordPress.
Website · WordPress.org · Documentation · Pricing · Community
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.
