Detecting Someone About to Commit or Just Recently Committed?

Siso: What do you think about tools to detect somebody about to commit or just recently committed some sort of secret in their code and alerts them on that? Or is that just closing the barn doors after the cows escaped? Siso: I think it's actually really important to do. Even if, even if it is after the horses left the barn, you, you, I said, I said cow, by the way, even if It's the cow. Like you would use horse, we can use horse.
