For us, it depends on who is doing the audit - if it is a customer direct audit where our customer is sending in their QA Manager or another employee is coming then it is a very restrictive audit, the fact that we are SQF certified plus a bunch of other certifications should be sufficient. For customer direct audits their employees and/or owner is required to sign an NDA.
If they are having a 3rd party Auditor come in we follow a slightly (less restrictive) process, there is no requiement for an NDA as (having been an Auditor myself) Professional Auditors follow a unwritten but very well understood code of silence - fact is when you are doing 5-7 audits a week I used to remember the faces, but everything else was a blur.
By the way, 24 years ago when I first became an SQF Auditor the idea was if you got SQF certified that ONE audit (or any GFSI Scheme audit) was meant to knock out the need for having to have multiple audits conducted by customers. Well, I guess that was the dream.
