I'm probably able to give this kind of advice myself but I certainly know a few C-levels at public companies listed on Eurostoxx 50 that don't have the proper digital practices

I have more than a couple times witnessed and thought "are you actually exchanging highly sensitive information with your board while using an open wifi in the same room as 5 of your direct competitiors, their staff and 1k random guys like me?"

They can ask legal or IT but either way it will end up being a project relegated on a larger roadmap and will not be properly implemented in a timely manner.

I guess what I'm looking for is a piece written by a reputable source (from their POV) such as Bloomberg or the WSJ. Any ideas?
