The scanning center is based in one of the three post relay centers that Switzerland has. To get into one of these, you need a batch. Then, inside this building (which is huge, like three soccer arenas), there is a glass building that has yet another batch only access with revolving doors that only has space for one person. So getting the mail out of there (aka stealing) will be hard. As for the concern that some person other than yourself will read your mail, that is true. As a customer, you will sign a voucher that you are ok with specific Swiss Post employees being able to read your mail.
