You’ll have 1,000x more headaches and burned operational cash getting everyone to approve everyone else’s every step than handling one security incident in a decade. And even with very tight security, something will still happen. It’s best to have backups, a good restore plan, and a relaxed culture*. Or that’s what I think, anyway.
I’m in SME land though, not big tech. But then again, 99.99% companies are.
