[CentOS] Your experience with os hardening tool - Bastille?

Hi All:)

I would like to start using a tool for automating of os hardening. I found
some informations about Bastille. One things which attracted my attention
is that in http://bastille-linux.sourceforge.net/news_updates.htm the last
post is from January 29th, 2012 :D

Is the tool ready to use at the moment with CentOS 6/7? Are there any
alternatives which you can recommend?

Thanks for all info :)

BR,
Rafal.
