Is this plugin supported anymore?

I have many sites using this plugin. Over time, this once useful plugin has become almost worthless. On at lease one site I can’t see legitimate logins in the log. On other sites, I’m unable to see login fails and login denials. These issues hamper the core purpose of this plugin.

I see that other users are having the same problem for sometime (months) without resolution, comment or inquiry by the author. Does anyone know if there are any alternative plugins?
