Mostly corporate security is about ass coverage, not about prevention of problems. Though that can be a useful side effect. Ass coverage is about legal liability. If something bad happens, can I wash my hands in innocence and not suffer consequences (financial, legal, etc.)? If "no", take measures until you can because this could get very expensive. Then the next question is "whose ass". Answer: literally anyone: service providers, your head of IT (who might get fired), your head of sales (who might have to explain to customer lawyers why their data leaked), the CEO, etc. They don't want to be on the spot for your mistakes. For public companies this is worse because now you have publicly traded shares in a very litigious environment with people looking for weaknesses that can be exploited to squeeze money out of any situation. And of course some of the tools in this space are made by publicly traded companies too. The easiest way to deal with security is applying a shotgun approach of applying any kind of stuff that is vaguely understood to maybe work. The actual effectiveness of these things is besides the point and of course much of it is snake oil. The point is that there are policies and they are being enforced. The more visible and annoying this is, the more effective it is in case of trouble as a means to say "well it wasn't my fault because we did X, Y, and Z". And of course a secondary effect of putting people on the job of securing a thing is that they will get busy doing their job to justify their existence. Which usually means a whole bunch of policy documents get written, tools get selected (preferably ones with big shiny reputations), and a lot of complexity gets introduced. There will be audits, consultants being consulted, chins being stroked, and a lot of money changing hands all for the assertion that "your ass is covered!" and by extension "theirs" as well. There are whole meta levels of ass coverage here. That's why security theater is a thing. Because there is a large audience of people that all need to be re-assured about having suitable amounts of ass coverage.
