Old school one when I was a security consultant for a bit (pre-automated pentest scammers). Medium size regulated fintech. Domain admin passwords and admin accounts were stuck on post it notes on a board in the machine room. If you went over the road to the college, asked to use the toilet, which they seemed fine with, and poked your 200mm lens out of the bathroom window you could snap them all.
Don't assume that level of competence improved with addition of technology.
