This is an official native implementation of the Bruteprotect service for Drupal by Parka, LLC. It is based on the WordPress project of the same name.

Botnets attack millions of websites everyday using their Internet-connected programs
BruteProtect is a security plugin that guards against botnets by connecting its users to track every failed login attempt across all installed users of the plugin. When you activate BruteProtect you become a part of an Internet-connected counter force that works against botnets.

BruteProtect logs every failed attempt community-wide
When an IP has too many failed attempts in a specific period of time, BruteProtect logs and blocks that IP across the entire BruteProtect network (your site included). The more users of BruteProtect, the safer we all are from traditional brute force attacks, and distributed brute force attacks that use many different servers and IP addresses.
