But I do have understanding. Because I've actually worked in a company with these safeguards. It handled extremely sensitive data of tens of millions of Britons. Normal engineers had no access to live data, 2 senior managers were the only ones in the engineering team with access to live passwords, etc. It is practical to put extremely heavy restrictions in place between engineers and the live data and they can still do their job. Our normal day-2-day was not impeded in any way. I only worked there 3 months for other reasons, but regardless of my view on other parts of their operations, their dedication and practical solution to protecting customer data impressed me.
