You can do this by creating an Anonymous User Segment in BCC and using it in Endeca Experience Manager.
The overall steps are as follows:
1) Go into BCC and create a User Segment called Anonymous. The rule for this User Segment should be "People whose Security Status is ANONYMOUS". To create a LoggedIn User Segment the rule should be "People whose Security Status is not ANONYMOUS".
2) Deploy your BCC project.
3) In Endeca Experience Manager in the User Segments section, create a User Segment with the same name ("Anonymous" or "LoggedIn")
4) Now you should be able to utilize the BCC User Segment you created previously, in Endeca slots.
A good link that explains these steps with screenshots and in more detail is here:
