And I think one of the nuances that really led us, even prior to an acquisition of a security company we made, was the fact that resilience from a security perspective doesn't really mean 100% stop something bad from happening. 

It means, okay, try to stop everything bad, of course, but if that doesn't work, and there's a good probability at some point, because of the complexity of systems, because of the sophistication of attackers, and in some cases, just because of accidents, there are going to be issues that arise. 

So resilience isn't this sort of this mindset of, make sure it never goes bad, but what do you do if it does?
