It's security is 'amazing' out the box because it only comes with an SSHd.
Well... OBSD is not that hard to learn... the main reason I suggested it is because its security out of box is amazing. The only other OS that compares in security with OBSD is Solaris... yes I said what you think I said... Solaris... I do not want to start a whole conversation about Solaris and OBSD being the most secure OS'es on earth but Solaris has a very advanced permissions system and is very powerful and secure. It is a good choice for someone with a Unix background, but looking for something user-friendly.
