It does boggle my mind as well. I’ve only ever worked in high security industries as a developer, and I’ve never had admin access unless I was on hardware deployment. Limited user accounts, Firewall blocks, Active Directory audits, and full file system and network log audits are the name of the game where I have been. Anything external gets flagged quickly by automation and anything severe gets an immediate phone call. Falling for a pen tester phishing more than once, getting your laptop stolen, and so on can get you on the poor performer list. It just seems obvious for critical domains.
