Problem with data privacy

sorry to put a tag that dont describe my problem

my problem is not about make indeed
I sell automation to companies,and I get refused lot of times due to the data privacy of the company,when you come to build automation for sensitive data automations,how you handle the problem of the comany’s data privacy when they cant give you data that is important?how you solve this problem?or you just ignore the automation that processes sensitive data and build automation for non-sensitive data??

thanks
