What's the next step after a security alert is delivered (i.e. does it go to a person first? does it get written down somewhere? are these bells constantly ringing?)? I promise I'm not a bad guy :)

The special care is taken to avoid alert blindness (i.e. too many similar alerts inevitably cause ignorance syndrome). I made a human study to make sure the timing of alert is enough to keep centinel's attention sharp, yet no important information event is missed.

The big picture - the action is taken to protect possibly compromised client's bank account.
