It is a busy Wednesday in Utica and your office manager gets an email that looks like it came from your supplier. New bank details, please update before Friday. It reads right, the logo is right, and she is three calls behind. She almost clicks pay.
With real security in place, that email gets flagged before it reaches her inbox, and if one slips through she has been trained to spot it and knows who to ask. Every account has a second login step, backups run where ransomware cannot reach them and old access gets shut off when people leave.
You do not think about it much, and that is the point. When your insurance carrier asks what controls you have, you send them a short report instead of guessing, and you sleep without wondering what is in the inbox.
