I'm lost at how that possibly compromises your security.
(Not defending Citi here--I much prefer Amex and their customer service.)
AmEx also likely knows where/when you're going if you put your tickets on that card. Clicking on something from e.g. United Airlines on AmEx's website pulls up the origins and destinations for each flight on the purchase. It's likely why they don't require you to file a travel notification.
