Password Policy Enforcer - Version 3.0 Protect your network from password crackers with Password Policy Enforcer. PPE allows you to create and enforce a password security policy for your network. A password policy will protect your network from crackers and allows you to synchronize your passwords with other platforms. Password crackers can detect weak passwords AFTER they have compromised your security, but PPE will stop weak passwords BEFORE they can be used on your network. Includes many options to customize the policy and an optional web client that allows passwords to be changed with a web browser.
