I just blocked some of the top management from connecting to our WLAN because I was testing a verifing feature for said WiFi that kicks all devices not listed in the DB.
It happened while my boss/senior/guidance was trying to show them the advantages of a centrally managed infrastructure.
He covered my ass well and tried to sell it to them as proof of a secure solution, that unknown devices couldn't log in.
I feel like human trash right now, but that's what you get for testing in production.
