We have released the Free version of PasswordSentry. The Free version has most of the features and functionality of the Pro version with the following exceptions:
No ProxyVPN (PVPN) plugin.
No AuthForm (AF) plugin.
No InterLinking (IL) plugin.
No BandwidthMonitor (BM) plugin.
No IP / Country Banning
The Free version allows people to try out our app on their server to get a feel of how PasswordSentry works. If and when you wish to upgrade to the Pro version, it's just a matter of purchasing a PS license, and then upgrading via the web-based PS AdminCP to convert from the Free version to the Pro version.
