Mailster reCaptcha vs BotBlocker Security – Firewall & Bot Protection

BotBlocker Security blocks 99% of automated attacks before WordPress even loads. No bloat, no slowdowns, no monthly fees for core protection. If your site is hit by login brute force, spam comments, fake Googlebots, content scrapers, or XML-RPC floods, you are not alone: bots generate over 47% of all web traffic. Most security plugins react after WordPress boots, wasting CPU and memory on every bad request. BotBlocker stops them at the door. Why site owners switch to BotBlocker Faster than the competition.
