It feels like you're going through some kind of security clearance.

To be honest, getting insight and access to a major company's networks and maybe customer data is perhaps the same kind of risk to the company as it is for the government to give someone access to (top) secret files. It might not be so much a negotiating tactic as awareness that more sophisticated spies and criminals than the ones in the OP article are targeting your company.
