I have been using their service for some time now. Not sure what security you are thinking about. You have the option of opening your photo galleries to the public or not. (I have not) Or are you thinking about ordering product via the CostCo web site? If your concern is about access to your photos, then I'd say printing them yourself is the only sure fire way to protect them. Certainly any place you download your images to has access to them at some fundamental level.
