1. Very easy to install and use, it is very well built. 2. Pro: Only two remote holes in the default install, in a heck of a long time! Con: Less (pre-built)

1. Very easy to install and use, it is very well built. 2. Pro: Only two remote holes in the default install, in a heck of a long time! Con: Less (pre-built) software than linuxes. 3. Something cheaper than a Razer-Blade. 4. You have not stated your requirements other than 'security', which if you demand no more than two remote holes in a very long time, then OpenBSD it is. If 'security' means something other than that you might want to go with a different OS.
