You could create some sort of utility method or add a method to one of your services that checks if it's your custom principal. Maybe something like:

        get
        {
            CustomPrincipal user = HttpContext.Current.User as CustomPrincipal;

            if (user == null)
                return GuestUser; // Just some default user object

            return user;
        }
    }
}
