buddypress

Hello,
I just made my signature wpmudev to enjoy all themes and plugins.
But one issue is worrying me now, I got close a home for clients not logged via a shortcode in a premiun BuddyPress theme (I'll use it because it is responsive) but typing the url in the browser can access any page of the site .
You would have an idea of ??how to protect the site url so you can not access the pages without being logged?

thank you
