Proactive Password Auditor™ (PPA™; former Proactive Windows Securiy Explorer) is a password security test tool that's designed to allow Windows® NT, Windows® 2000, Windows® XP and Windows Server 2003-based systems administrators to identify and close security holes in their networks.

Password hacking is one of the most critical and commonly exploited network security threats. Too often, users like to use simple and easy-to-remember passwords such as repeating characters, simple words, and names. In addition, some network administrators forget to purge terminated employees from the system, force people to change passwords often, or lock out users after a numberof failed attempts.

Proactive Password Auditor™ helps secure networks by executing an audit of account passwords, and exposing insecure account passwords. If it is possible to recover the password within a reasonable time, the password is considered insecure.
