The 10pm Friday story.
Something breaks at 10pm on a Friday. Here’s what happens: I know about it before you do. The systems notify me, I get in, find out what happened, assess it, and take the best measures to repair or restore. Handled looks like this: you don’t even know it happened. And if you do know, it’s because I told you, and because it’s already fixed.
The padlock in the browser, the software patches, the malware scanning: all part of the deal, not add-ons.
