I'd walk away. This is insulting, toxic, and highly questionable, unless you've recently made an appearance on the FBI's 10 most wanted list. If they can justify this very unusual ask and you still like the deal, I think you should require compensation that offsets your risk.I've been required to have bonding insurance when I worked for financial institutions, which I obtained with a rider to my commercial liability insurance, at a reasonable extra cost. I'd offer an insurance bond as an alternative and insist they pay for the extra expense. You could also have them partially redact sensitive information before it is given to you.
