Mediabrowser Controlling access

Hi,
It is possible to add "Controlling access" to mediabrowser ?
It seems that mediabrowser see all library content without any controlling access and I could not change it on serviio console.
For example if I'll open library content for external internet access, I would like to add some folder restriction, is it possible ?
Thanks
