With ISO27001 or SOC 2, I have more information about the other party's ability to manage those risks than just taking their word for it. I'm trusting a third party auditor to vouch for them.
Fraud undermines all kinds of relationships and yes LLMs make it worse. The last job we opened I got hundreds of perfect cover letters asserting the candidates met all of the criteria. Bah.
My perhaps naive hope is that a few of these companies involved will face criminal fraud charges and we will start to develop new reflexes as a society that just bc LLMs making lying very very easy, there are still consequences.
